NIH and Gates Foundation lay out ambitious plan to bring gene-based treatments for HIV and sickle cell disease to Africa – Science Magazine

Posted: October 24, 2019 at 2:45 am

A new $200 million collaboration aims to speed development of genetic cures for people in Africa with sickle cell disease (above) and, separately, HIV infection.

By Jon Cohen, Jocelyn KaiserOct. 23, 2019 , 5:00 PM

Two major U.S. biomedical research funders plan to each put at least $100 million over 4 years toward bringing cutting-edge, gene-based treatments to a part of the world that often struggles to provide access to even basic medicines: sub-Saharan Africa. The National Institutes of Health (NIH) and the Bill & Melinda Gates Foundation today announced the unusual collaboration to launch clinical trials for gene-based cures for HIV and sickle cell disease within the region in the coming decade.

The ambitious goal is to steer clear of expensive, logistically impractical strategies that require stem cell transplantation, and instead develop simpler, affordable ways of delivering genes or gene-editing drugs that can cure these diseases. Yes, this is audacious, NIH Director Francis Collins said during a press teleconference this morning on the project. But if we dont put our best minds, resources, and visions together right now, we would not live up to our mandate to bring the best science to those who are suffering.

After decades of work and setbacks, the traditional gene therapy approach of delivering DNA into the body to replace a defective gene or boost a proteins production is now reaching the clinic for several diseases, including inherited blindness, neuromuscular disease, and leukemia. Animal studies and some clinical trials have suggested that two diseases prevalent in Africa, HIV and sickle cell disease, can be treated by gene therapies or newer genome-editing tools such as CRISPR.

But in most cases, introducing those therapeutic genes or the components of a genome editor involves removing stem cells from the body, adding or modifying genes, then reinfusing the cells back into the body. That is essentially a stem cell transplant with ones own cells, an expensive procedure that is also typically risky because physicians wipe out most of a patients existing stem cells with chemotherapy so the corrected cells can engraft and grow. It remains out of reach for most people in sub-Saharan Africa, where few places have the medical infrastructure to support such intensive interventions.

Yet sub-Saharan Africa is home to about two-thirds of the 20 million people with sickle cell disease and the 38 million living with HIV. The NIH-Gates partnership is an incredible opportunity to find new therapies and possible cures for two diseases that affect millions of Africans and to make them available at affordable costs, said Matshidiso Moeti, who heads the Regional Office for Africa at the World Health Organization.

Anthony Fauci, director of NIHs National Institute of Allergy and Infectious Diseases, noted that if this collaboration pans out, it could also lead to enormous cost savings. If we do successfully achieve an HIV cure, it will ultimately be important not only for millions of individuals with HIV, but also will save hundreds of billions of dollars in health care costs, said Fauci, whose institute already funds a major HIV cure initiative.

In sickle cell disease, which involves a defect in the oxygen-carrying hemoglobin in red blood cells, several ongoing gene therapy and gene-editing clinical trials in the United States and Europe are either adding a new hemoglobin gene to cells or turning on the gene for a fetal form of the protein. Other clinical trials for HIV have used CRISPR or other genome editors in stem cells to cripple a receptor, CCR5, that the virus depends on to establish infection.

Instead of modifying a persons stem cells and transplanting them back, the new collaboration will seek to ferry a therapeutic gene or gene-editing tools directly into the body (in vivo) with vectorssuch as harmless viruses or nanoparticles, Collins said. The treatment itself would be similar to a simple blood transfusion. Although studies are already underway with viral vectors that deliver new genes to certain tissues in people, in vivo gene therapy has only been used to modify blood stem cells in animal models of certain diseases. Figuring out how to home in on and modify those cells in people is a big part of the collaborations plan, Collins said.

Hematologist Alexis Thompson of the Northwestern University Feinberg School of Medicine in Chicago, Illinois, who is involved with some sickle cell gene therapy trials, calls the NIH-Gates collaboration phenomenal.But, she says, a more urgent need is to expand efforts to screen newborns in Africa for sickle cell disease and treat them with antibiotics; at the moment, the majority die before age 5 from bacterial infections because the sickled cells impair the spleens ability to filter bacteria and make antibodies. Unless more children with sickle cell disease mutations survive longer, there will be few to be cured with the new gene-based treatments, Thompson says. Its almost being able to crawl or walk before you sprint.(Gates and NIH say they plan to support screening efforts outside of the new collaboration.)

For HIV, a big impetus for the cure push builds on two people infected with the AIDS virus who were cured with stem cell transplants. These two men each had blood cancers that required the transplants, which intentionally used blood from donors who had white blood cells with crippled CCR5 receptors. After the transplants, whatever HIV remained in these men could not enter new host cells, and their infections petered out. This new initiative hopes to speed development of direct injections of gene editor components that can target theCCR5gene in blood cells and cripple it. The potential beauty of in vivo gene editing is that it might be given ultimately as a single shot, curing everyone in a scalable manner, says Steven Deeks, a leading HIV cure researcher at the University of California, San Francisco.

The collaboration will also try to speed development of more experimental interventions that directly excise HIVs genetic material from a patients cells or allow people to artificially make superpotent antibodies against the virus. This might be science fiction now, but one day may be a real possibility, Deeks says.

United Therapeutics receives permit for cell therapy facility build-out at Mayo – Jacksonville Daily Record

Posted: October 24, 2019 at 2:45 am

United Therapeutics received a building permit Tuesday for a $9.5 million build-out of its cell therapy facility on the second floor of Mayo Clinics Discovery and Innovation Building.

The 21,843-square-foot space will house an automated stem cell manufacturing site, which is one of the first of its kind in the country. The Whiting-Turner Contracting Co. is the project contractor.

The technology, approved by the FDA in 2018, allows the Mayo Clinic Center for Regenerative Medicine to produce cells from the bone marrow of a stem cell donor in large enough quantities to be used as treatments in clinical trials. It allows for the treatment of multiple patients at the same time.

Construction began in 2017 on the $32.4 million building at 14221 Kendall Hench Drive. It held a grand opening in August.

The first floor houses three ex-vivo lung perfusion surgical suites used for lung restoration, another form of regenerative medicine. It turns donor lungs, which previously would have previously been unusable, into viable transplant organs. United Therapeutics also collaborates with Mayo Clinic on lung restoration.

The third floor houses the Life Sciences Incubator for biotech entrepreneurs, which offers coworking space, wet labs, business resources, networking and entrepreneurial training.

Global Wound Care Market Outlook to 2024: New Product Approvals/Launches, Emergence of Stem Cell Therapy For Wound Healing – P&T Community

Posted: October 24, 2019 at 2:45 am

DUBLIN, Oct. 22, 2019 /PRNewswire/ -- The "Wound Care Market - Global Outlook and Forecast 2019-2024" report has been added to ResearchAndMarkets.com's offering.

The global wound care market is growing at a CAGR of over 5% during the forecast period 2018-2024.

The adoption of wound care biologics is augmenting the growth of the global wound care market. The commercial availability of a wide array of wound biologics is likely to encourage many end-users to use them in treating wounds as they are clinically proven, safe, and effective than other products.

The growing incidence of infections caused in lesions is another factor accelerating the growth of anti-microbial dressings market segment. Anti-microbial agents such as chlorhexidine, maggots, silver, iodine, and honey are increasingly becoming important in the global wound care market. Therefore, the incorporation of anti-microbial agents in wound dressing products is improving clinical outcomes for the treatment of wounds, thereby driving the global wound care market.

This research report includes detailed market segmentation by products, wound type, end-users, and geography. The increase in the geriatric population is a major contributing factor for the growth of the advanced wound care segment as the prevalence of diabetes and other diseases is more common in the elderly age group than youth.

The advanced segment is also growing as the majority of market players are offering innovative products to meet the demand for wound care worldwide. The rising incidence of diabetes and associated diabetic foot ulcers in the elderly population globally is fueling steady growth for traditional products.

The market is also growing steadily as products such as gauze bandages and adhesive bandages witness sustainable demand for small cuts, bruises as well as for chronic wounds and burns, especially in developing countries. Developing regions such as Africa, Asia, and Latin America are the largest contributors to the traditional products.

The acute wound market is growing mainly due to the rise in surgical site infections (SSI) and the increase in the number of burn cases worldwide. Chronic wounds do not heal through the normal healing process. The segment is growing due to the growing burden of diabetic foot ulcers, venous leg ulcers, pressure ulcers, and some surgical site infections that do not heal naturally or with medicines.

The shift from traditional lower technology wound care treatments to the adoption of advanced treatments is a major factor for the high share of the hospitals and specialty wound clinic segment. Long-term care facilities segment is growing at a steady pace because of the growing incidence of chronic wounds due to the increase in chronic diseases such as diabetes. The growing elderly population is contributing to the growth of the segment as they are more prone to chronic diseases.

Report: The judge in Oklahoma admits that part of the $ 572 million fee for J & J in the case of opioids was miscalculated – asume tech

Posted: October 24, 2019 at 2:44 am

A judge in Oklahoma admitted that a miscalculation has led to his charging excessive fees to one of the world's largest drug companies in a case involving opioids.

The Associated Press said Tuesday that Cleveland County, Oklahoma, District Judge Thad Balkman has acknowledged the failure to charge a $ 107,000 charge for $ 107 million, for a premium of $ 572 million Johnson & Johnson, headquartered in New Brunswick, New Jersey, would have to pay the state.

Balkman told J & J to pay the $ 572 million in August after finding that the drug maker in Oklahoma had created a "public nuisance" by helping to fuel the opioid crisis. J & J appealed the verdict last month, stating that Balkman had made a miscalculation of the $ 107 million charge.

In its Tuesday report, the Associated Press reported that J & J lawyers are seeking an additional reduction in the amount. With the 107,000 US dollars, a program for the treatment of opioid-dependent born babies should be developed.

Regardless, the Wall Street Journal on Tuesday reported that the country's top three drug distributors McKesson, AmerisourceBergen and Cardinal Health were talking about settling opiate disputes worth $ 18 billion. Citing the persons familiar with the discussions, the newspaper reported that the amount was paid out over a period of 18 years, while J & J itself was being discussed for contributing additional money.

J & J, the aforementioned distributors and several other companies are facing more than 2,000 litigation by state and local authorities that their marketing of opioid painkillers has contributed to the nationwide epidemic of drug additions. The cases are part of a multiple district litigation (MDL) hearing this month in the US District Court for the Northern District of Ohio.

One of MDL's best-known companies, Purdue Pharma, filed for more than $ 10 billion in bankruptcy last month, although several attorneys general have criticized this move. Other MDL companies include other opioid manufacturers and retailers such as Walgreens.

Are Pricey Fertility Treatments Helping Women Have Babies…Or Preying On Them? – Women’s Health

Posted: October 24, 2019 at 2:44 am

Lauren Citro, 32, has been trying to conceive for nearly six years.

Shes received fertility treatments at four clinics in three states.

In her effort to exhaust all options, shes sampled almost every intervention recommended: immunology testing, assisted hatching, supplements, acupuncture, intracytoplasmic sperm injection, testicular sperm extraction and the list goes on.

She trusted her doctorsand didnt want to drive herself crazy Googling things when fertility treatment is already a high-stress processbut the info she received from providers tended to be minimal and conflicting. Case in point: She went through whats known as an endometrial scratch that was described as highly recommended at her third clinic, only to find out it was entirely dismissed at a fourth place, because of the trauma it causes.

So Citro finally started doing some sleuthing online. Now, she asks a lot more questions. And as time goes on, and the more she hunts for evidence, the less shes willing to try different options. Our rationale used to be cant hurt, might help, Citro, a nurse in San Diego, says of the additional treatments she and her husband had during six IVF retrievals and four transfers (total cost: more than $100,000). But thats not necessarily the case. (She points to another example: a $7,000 testicular extraction of sperm that the results said had no impact on our outcome.)

About 10 percent of women in the U.S. struggle to conceive or stay pregnant, and nearly 2 percent of all births in the country are via in vitro fertilization (IVF), which costs upwards of $15,000. But beyond that, more than two-thirds of fertility clinic patients spend up to $10,000 per cycle on so-called optional extras or add-onsemerging techniques a clinic might offer on top of mainstream fertility treatment (i.e., IVF), supposedly to improve the odds even further and typically (almost always) for an additional cost. Add-ons, like the ones Citro tried, are rarely covered by insurancethough, in general, getting any part of your fertility treatment covered is still not the norm.

On some level, fertility treatment is like going to a Chinese restaurant and picking items from a dim sum cart, and it shouldnt be that way.

Many health-care providers are becoming increasingly worried that fertility extras come with costs far beyond monetary ones. Out of a group of routinely offered add-ons, 26 of 27 lacked rigorous, conclusive research to back their effectiveness for improving pregnancy or birth rates, found a recent investigation conducted by Oxford University and published in the British Medical Journal. Plus, the research IDd at least one of the procedures (preimplantation genetic screening, which well get to later) as potentially harmful.

On some level, fertility treatment is like going to a Chinese restaurant and picking items from a dim sum cart, and it shouldnt be that way, says Rachel Ashby, MD, an ob-gyn at Brigham and Womens Hospital Center for Infertility and Reproductive Surgery and an instructor at Harvard Medical School.

Piling on to the controversy is the fact that some experts believe there are flaws in the way U.S. fertility clinics are overseen. The U.S. requires fertility centers to report the basic details of each treatment cycleoutcomes, infertility diagnosis, number of embryos transferred, use of fresh or frozen embryos, donor or non-donor eggsto the Centers for Disease Control and Prevention (CDC) each year.

So in that sense, the industry is highly regulated. While that sounds like a positive fact, there is no penalty if a clinic doesnt report to the CDC; its simply listed as non-reporting.

The American Society for Reproductive Medicine (ASRM) also offers practice guidelines and opinions on how clinics should operate, including whether certain add-ons should be used on all patients, but businesses are not required to follow these either.

Many experts in the field say that for a lot of interventions, the science isnt there yet. That doesnt mean it will never advance, or that add-ons unanimously deserve a shady rap. But until we know whether an add-on works for a certain patient groupand whether the potential benefit outweighs the risksome believe they should be offered sparingly, with the science (and its flaws) and the pros and cons laid out clearly and deliberately for every single patient. Unfortunately, that doesnt always happen.

Whew, thats a lot to unpack. The data is messy and unfinished. Clinic regulation is loose. Yet women remain hopeful. And how could they not when faced with the opportunity to do everything in their power to start a family? WH goes deep

The debate is a minefield, starting with the word add-on itself. These treatments are generally unproven, yes. Still, many healthcare providers and patients are so insistent about the value that they bristle at the mere suggestion that add-ons are frivolous.

Deborah Anderson-Bialis, a founder of FertilityIQ, a website that provides independent analysis of clinics and doctors, points out that proponents would much prefer the phrase options for treatment to add-ons, because the latter has a negative connotation and implies theyre unnecessary. Some medical publications use the term adjuvants instead of add-ons.

This year, the United Kingdoms fertility regulatory agency began rating nearly a dozen add-ons with a traffic light system, with green reserved for procedures shown to be effective and safe by at least one good-quality randomized clinical trial (the gold standard of research). Not one has received a green rating yet. And if youre wondering, the U.S. has far less regulation than the U.K., which may stem from Congresss 1996 ban on the use of federal funds for research related to the creation of embryos.

Heres a snapshot of the points of contention:

The most commonly advocated add-on in recent years is preimplantation genetic testing for an abnormality called aneuploidy, or PGT-A. Its also one of the most expensive ($3,000 to $8,000, depending on where you live). Some practices, particularly in competitive markets like New York, recommend it (and sometimes insist on it) for 100 percent of patients, according to Norbert Gleicher, MD, founder of New Yorks Center for Human Reproduction. But there is so far no evidence that it increases live birth rates, which is why insurance doesnt cover it. The U.K.s watchdog group has given the screening a red-light rating, as it risks damaging fragile embryos by removing cells to test for these abnormalities. Meanwhile, an ASRM committee analyzed the available studies and concluded there was insufficient evidence to recommend the routine use.

But this is where things start to get complicatedlike, really complicated. Proponents of PGT-A will point out that theres a potential upside with PGT-A in women who have miscarried (aneuploidy is thought to be the biggest cause of miscarriages). And while PGT-A did not improve the live birth rate in all subjects, women over 38 who had PGT-A screening were found to have a better chance of achieving a live birth and were significantly less likely to have a miscarriage, possibly because they avoid being implanted with an embryo thats genetically abnormal from the get-go, found a study in Human Reproduction. This may be reason enough for some women to choose it. That all being said, the study authors note that it remains to be seen whether the benefits outweigh the drawbacks of cost and invasiveness.

This is a tool we can use to lessen our patients suffering and also give them some peace of mind that the pregnancy thats created is genetically normal, argues Catha Fischer, MD, an ob-gyn at Reproductive Medicine Associates of New Jersey. Two sides to every coin, in a sense.

Intracytoplasmic sperm injection (ICSI) is a common add-on.

This is when the single best-looking sperm (and it definitely is a beauty contest; its done by sight) is picked to be injected into the egg. (In conventional IVF, the egg is put in a petri dish with a bunch of sperm, and whichever one gets to it first is the winner.) For people who have no evidence of male-factor infertility, which is at least 50 percent of patients, the chances of getting pregnant are identical whether you pay the $1,000 to $2,500 for ICSI or not. Yet ICSI is being offered to people who arent, as doctors say, medically indicated for the issue. In fact, 66 percent of IVF cycles used ICSIand only 32 percent actually had male-factor infertility aloneper the latest CDC report.

Whats more, the British fertility regulatory authority warned that ICSI has slightly more risk than other fertility treatments; eggs may be damaged when theyre cleaned and injected with sperm. ICSI may also be associated with genetic and developmental disorders, though its not clear whether this is connected to the treatment itself or the infertility that prompted its use.

The add-on is so controversial that it has prompted experts to stand up and scream at each other at otherwise staid medical conferences, which Anderson-Bialis has witnessed. The method uses drugs to suppress the mothers immune system, based on the theory that her immune system goes out of control and mistakenly targets her pregnancy, possibly causing infertility, failed IVF, or miscarriage.

A little perspective here: Those are just a few examples of hot-button add-onsfrom a list of nearly 30. And not every supplemental fertility tool has such clear potential downsides. Most others just dont have verified positivesand cost a lot.

The yes mentality, explained

The fact that patients are embracing add-ons makes total sense: Youre determined to grow your family, and the fertility window is cracked open only so long, right? It can feel as if there simply isnt time to wait for conclusive research. And given the incredible expenses of fertility treatment, many women prefer to walk away knowing they gave it their absolute best shot.

We spent a lot of money because we wanted to feel like we did everything we could, says Citro, who notes that for months after her last cycle, it was difficult to talk about her long quest for parenthood without crying. Its an emotional roller coaster.

In these situations, many people are understandably searching for a sense of control, says psychologist Jessica Zucker, PhD, who specializes in womens reproductive and maternal mental health. When your body isnt doing what you wanted or expected it to do, all sorts of feelings can result from thisdisappointment most especially. But you have ownership over what youre willing to go through to try to conceive. So its a good idea to get familiar with your limits.

There is a mistaken notion that medical treatments are either futile or backed by large, well-controlled randomized studies."

These extras also glitter with a success halo. Its tempting to revel in positive stories in online communities and message boards and read into the content. But, says Dr. Ashby, anecdotes are two steps below voodoo in terms of value. There are more than 200you read that rightvariables that can impact an IVF cycle, according to Mandy Katz-Jaffe, PhD, scientific director of the fertility clinic network CCRM. So its not possible to pinpoint one single variable as responsible for the birth of a healthy baby.

However, when youre struggling with infertility, theres power and comfort in believing. Maybe Ill be the one person in 1,000 it works for, you imagine. Katie Coester, 37, of Washington, D.C., went to a clinic that didnt try to upsell, as she describes, and recommended only two add-ons: testing embryos for chromosome abnormality and endometrial scratching. (Her IVF was covered by insurance; the additions cost her some $2,000.) She also scoured message boards for possible ways to increase her odds, which is how she ended up doing acupuncture, watching funny movies (a small study done in Israel recommended laughter), and eating, er, pineapple core.

Coester had only one fallopian tube and was 31 when she started treatment. She had fairly quick successbut if she hadnt, she thinks she would have paid for anything and everything. You think, Ive come this far, says Coester, who is now a mother of two. Even with insurance coverage, we had to say, How far are we willing to push my body? What is the emotional toll were willing to take?

This brings us to the line the medical world is currently struggling to straddle: finding middle ground between forgoing ineffective and costly treatments and offering patients potentially helpful ones that just may not have a large randomized controlled trial behind them, says Zev Williams, MD, PhD, chief of reproductive endocrinology and infertility at the Columbia University Fertility Center.

There is a mistaken notion that medical treatments are either futile or backed by large, well-controlled randomized studies, says Dr. Williams. The reality is much more nuanced than thatthere is a large area in the middle where there is either preliminary or limited data showing benefit.

Karina Shreffler, PhD, a professor of human development and family science at Oklahoma State University, says the super-solid research studies are extremely expensive and difficult to secure funding for and also complicated to run. You need a large enough sample of diverse women receiving a specific kind of treatment (and a control group of similar women who dont receive the treatment). Even then, she says, youd be working within the challenge that only some women seek fertility treatment, and that theyre different from the women who dont (due to lack of finances, ethical reasons, and geography). So that poses additional considerations when it comes to interpreting the results.

Until the science catches up (if it does, that is), the Big Question remains: Why do clinics offer these treatments in infantile stages? First, many interventions in medicinenew cancer treatments, for instanceare instituted before theres a ton of research if there is even a slight inkling that they may help. Or, sadly, the more cynical take: Offering add-ons gives clinics a financial edge, many experts suggest. Because so few insurance companies pay for PGT-A, for example, private clinics and labs get the full fee, as opposed to insurance companies lower reimbursement rates, making the procedure a moneymaker for the fertility industry. These things are highly profitable, says Arthur Caplan, PhD, founding director of NYU Langones Division of Medical Ethics. Its We have desperate people here, and we can sell them anything.

If youre in the market for treatment, the bottom-line advice is to hitch your wagon to a health-care professional who is willing to take the time to educate youand to know you. If you meet with a doctor, and all youre getting is this is what you should do, then you need to find a new one, says Dr. Ashby. A praiseworthy provider will help you analyze and interpret conflicting fertility datawhich is tough to do as a laypersonand will also draw from their experience treating patients with cases similar to yours. (Dr. Fischer likes to tell patients, If youre thinking about Googling a question, just email me instead. I can shield you from worrying over misinformation or a misunderstanding.)

Grappling with infertility can suck the life out of you. But in the end, the best you can do is try to make an informed decision.

With all the new fertility and egg-freezing pop-ups, its critical to consider quality and experience over flashy marketing and trinkets. A doctors goal, always, should be to give every patient the very best chance of success and to practice patient-focused and evidence-based care, while also being transparent about the data behind medical recommendations, says Dr. Williams. More safeguarding suggestions: Consider a facility that is attached to a university, and seek out multiple opinions before green-lighting a procedure for yourself.

Citro, for one, needs a break from it allthe doctors, the studies, the clinics, the add-ons, the Googling. She hit pause for now but has not lost hope. After nearly six years of letting infertility dominate her life, she and her husband took a break from IVFand a vacation to Europe. We know well go back to treatment eventually, she says. We really hope that we end up with kids. Whatever happens, I want to look back and know that I made the very best decisions for me.

How to Prep for the Unknown Grappling with infertility can suck the life out of you. But in the end, the best you can do is try to make an informed decision. Go in with an investment plan of sorts (in your mind or on paper) that details what youre comfortable putting into the process monetarily and emotionally. Brainstorm in advance what youre willing to devote to thisthe money, the energy, the time off from work if you need, perhapsand what youre not, says psychologist Jessica Zucker, PhD. Maintain flexibility. Its okay if your expectations and limitations evolve or change over time. Try not to judge yourself at any stage of the process, she stresses.

Research Roundup: Genomic Dark Matter Mutation and More – BioSpace

Posted: October 23, 2019 at 8:47 am

Every week there are numerous scientific studies published. Heres a look at some of the more interesting ones.

Mutation Found in Dark Matter of the Genome New Target for Cancer

The so-called dark matter of the genome is the non-coding regions that make up about 98% of the genome. Researchers at the Ontario Institute for Cancer Research (OICR) recently identified a novel cancer-driven mutation in this region that is linked to brain, liver and blood cancer. They published the two studies in the journal Nature.

Non-coding DNA, which makes up 98% of the genome, is notoriously difficult to study and is often overlooked since it does not code for proteins, said Lincoln Stein, co-lead of the two research studies and Head of Adaptive Oncology at OICR. By carefully analyzing these regions, we have discovered a change in one letter of the DNA code that can drive multiple types of cancer. In turn, weve found a new cancer mechanism that we can target to tackle the disease.

The mutation is dubbed U1-snRNA, and it appears to disrupt normal RNA splicing, which changes the transcription of genes that drive cancer. The mutation was identified in tumors of patients with specific subtypes of brain cancer and was found in almost all of the samples. The cancer was sonic hedgehog medulloblastoma. It was also found in samples of chronic lymphocytic leukemia (CLL) and hepatocellular carcinoma.

Our unexpected discovery uncovered an entirely new way to target these cancers that are tremendously difficult to treat and have high mortality rates, said Michael Taylor, pediatric neurosurgeon and senior scientist in Development and Stem Cell Biology and Garron Family Chair in in Childhood Cancer Research at The Hospital for Sick Children and co-lead of the studies. Weve found that with one typo in the DNA code, the resultant cancers have hundreds of mutant proteins that we might be able to target using currently available immunotherapies.

Diagnosing Lyme Disease in 15 Minutes

About 300,000 people are diagnosed with Lyme disease each year. Borrelia burgdorferi is transmitted by the bite of infected Ixodes ticks, and if untreated, can cause neurologic, cardiac, and rheumatologic complications. Current testing involves two complex tests, ELISA and western blot. Researchers have developed a rapid microfluidic test that can provide comparable results in as little as 15 minutes. It will require more refinement and testing before widespread use.

Gene Therapy for Wet Age-Related Macular Degeneration Shows Promise

Research was recently presented on six patients who received a gene therapy for wet age-related macular degeneration (AMD). The patients have gone at least six months without continued injections for the disease that were previously required every four to six weeks. The therapy, which is injected into the eye, generates a molecule much like aflibercept, a broadly used anti-VEGF drug.

How Dementia Spreads Throughout Brain Networks

Frontotemporal dementia (FDT) is similar to Alzheimers disease, but tends to hit patients earlier and affects different parts of the brain. Researchers studied how well neural network maps made from brain scans in healthy people could predict the spread of brain atrophy in FTD patients over several years. They recruited 42 patients at the UCSF Memory and Aging Center with a form of FTD and 30 with another form. They received MRI scans and then follow-up scans a year later to determine how the disease had progressed. They found that the standardized connectivity maps were able to predict the spread of the disease.

Mucus and Microbes: A Therapeutic Gold Mine.

A specific type of molecule called glycans that are found in mucus prevent bacteria from communicating with each other. Mucus also prevents the bacteria from forming infectious biofilms. It is also pointed out that more than 200 square meters of our bodies are lined with mucus. There are hundreds of different types of glycans found in mucus, and most of them are responsible for suppressing bacteria. Katharina Ribbeck, a professor at the Massachusetts Institute of Technology, says, What we have in mucus is a therapeutic gold mine.

Mechanisms that Regulate Brain Inflammation

The role of brain inflammation in diseases like Alzheimers and Parkinsons is becoming better understood. Researchers recently identified mechanisms that regulate brain inflammation, which has the potential to open new avenues for treating and preventing these diseases. The scientists found that a protein called TET2 modulates the immune response in microglia, immune cells in the brain, during inflammation. In mice engineered not to have TET2 in the microglia, neuroinflammation is reduced. Normally, TET2 with other proteins regulates the activity of genes by removing specific chemical markers from DNA, but TET2 appears to behave differently in microglia.

Pilot Study: Even Short-Term Vaping Causes Lung Inflammation

Research out of The Ohio State University Comprehensive Cancer Center found cellular inflammation was caused by e-cigarette, i.e., vaping, use in both long-term smokers and people who did not smoke. They used bronchoscopy to evaluate for inflammation and smoking-related effects and found a measurable increase in inflammation after only four weeks of vaping without nicotine or flavors. The amount of inflammation was small compared to the control group, but the data suggests that even short-term use can result in inflammatory changes at a cellular level. Inflammation in smoking is a driver of lung cancer and other respiratory diseases.

New study reveals why breast cancer spreads to the brain – USC News

Posted: October 23, 2019 at 8:44 am

Most cancers kill because tumor cells spread beyond the primary site to invade other organs. Now, a USC study of brain-invading breast cancer cells circulating in the blood reveals they have a molecular signature indicating specific organ preferences.

The findings, which appear in Cancer Discovery, help explain how tumor cells in the blood target a particular organ and may enable the development of treatments to prevent the spread of cancers, known as metastasis.

In this study, Min Yu, assistant professor of stem cell and regenerative medicine at the Keck School of Medicine of USC, isolated breast cancer cells from the blood of breast cancer patients with metastatic tumors. Using a technique she developed previously, she expanded or grew the cells in the lab, creating a supply of material to work with.

Analyzing the tumor cells in animal models, Yus lab identified regulator genes and proteins within the cells that apparently directed the cancers spread to the brain. To test this concept, human tumor cells were injected into the bloodstream of animal models. As predicted, the cells migrated to the brain. Additional analysis of cells from one patients tumor predicted that the cells would later spread to the patients brain and they did.

Yu also discovered that a protein on the surface of brain-targeting tumor cells helps them to breach the blood-brain barrier and lodge in brain tissue, while another protein inside the cells shield them from the brains immune response, enabling them to grow there.

We can imagine someday using the information carried by circulating tumor cells to improve the detection, monitoring and treatment of the spreading cancers, Yu said. A future therapeutic goal is to develop drugs that get rid of circulating tumor cells or target those molecular signatures to prevent the spread of cancer.

Yu is a member of the Eli and Edythe Broad Center for Regenerative Medicine and Stem Cell Research at USC, and her laboratory is located in the USC Norris Comprehensive Cancer Center.

In addition to Yu, other authors of the study are Remi Klotz, Amal Thomas, Teng Teng, Sung Min Han, Oihana Iriondo, Lin Li, Alan Wang, Negeen Izadian, Matthew MacKay, Byoung-San Moon, Kevin J. Liu, Sathish Kumar Ganesan, Grace Lee, Diane S. Kang, Michael F. Press, Wange Lu, Janice Lu, Bodour Salhia and Frank Attenello, all of the Keck School of Medicine; Sara Restrepo-Vassalli, James Hicks and Andrew D. Smith of USC Dornsife College of Letters, Arts and Sciences; and Charlotte S. Walmsley, Christopher Pinto, Dejan Juric and Aditya Bardia of Massachusetts General Hospital.

The study was supported by grants from the National Institutes of Health (DP2 CA206653) the Donald E. and Delia B. Baxter Foundation, the Stop Cancer Foundation, the Pew Charitable Trusts and the Alexander & Margaret Stewart Trust, the SC CTSI pilot grant (UL1TR001855 and UL1TR000130), a California Institute for Regenerative Medicine (CIRM) postdoctoral fellowship and a CIRM Bridges award (EDUC2-08381), and the National Cancer Institute (P30CA014089).

Genes Linked to Sex Ratio Associated With Infertility – Technology Networks

Posted: October 22, 2019 at 2:50 pm

One of the more recent trends among parents-to-be is the so-called gender reveal, a party complete with pink or blue cake to answer the burning question, "Is it a boy or girl?" After all, it's presumed that there's a 50-50 chance you'd have one or the other. In a new article published inCurrent Biology, Michigan Medicine researchers studying the sex chromosomes have discovered genes that, at least in mice, skew that assumed ratio to favor one sex and that could have major implications for male infertility.

"There are a handful of genes known to underlie male infertility but there's still a lot unknown," says Alyssa Kruger, a Ph.D. student within the Department of Human Genetics. Kruger, who works in the lab of principal investigator Jacob Mueller, Ph.D., and their colleagues have been studying the X and Y chromosomes -- which are delivered by sperm to an egg to determine an offspring's sex--across species and across millions of years of evolution.

Sex chromosomes are unique, Kruger explains, because while they were once an identical pair of chromosomes, they independently evolved distinct sets of genes. Upon examining mice sex chromosomes, they found two recently evolved X-linked gene families that are found only in mice. Interestingly, these genes are also present multiple copies. To figure out what the genes are responsible for, Kruger's team removed them from the genomes of some mice using CRISPR and other technologies.

Removing all copies of one X-linked gene family produced mice whose offspring were biased towards being male by a ratio of 60-40. This discrepancy wasn't a result of more Y-bearing sperm--the number of X and Y sperm remained the same in the mice. "This suggests to us that this gene is impacting the relative fitness of X versus Y sperm, but we don't know how. Maybe the Y-bearing sperm are swimming faster or in a straighter line, we don't yet know," says Kruger.

Next, the team decided to increase the copy number of both X-linked gene families to get a better sense of why there are multiple copies. They duplicated these regions of the genome and surprisingly, this also skewed the sex ratio 60-40, only this time in favor of female offspring.

Kruger says that these X-linked gene families appear to be a "dial" for the fitness of X-bearing sperm. Interestingly, a related gene family on the Y-chromosome is also present in multiple copies and may serve an analogous role in Y-bearing sperm. The same sex-skewing has been observed in other experiments using fruit flies and, she says, something similar could be present in humans, though harder to observe. "We think of the back and forth copying of these genes as kind of an evolutionary arms race between the X and Y chromosomes that has played out over 20 million years to maintain the 50-50 male to female sex ratio."

Beyond their sex-ratio effects, an important feature of the two genes is that their complete removal leads to male mouse infertility.

Specifically, removing all copies of both X-linked gene families prevented male mice from producing sperm; they were unable to transform round cells to the elongated cells with a head and tail we recognize as sperm. Says Kruger, "There are a lot of cellular processes that have to happen that aren't. We hope this model will give us a better understanding of the developmental process of sperm production."
