In choices of fictional books to read I gravitate toward sci-fi and fantasy. For example,in late 2014 and through the first few months of this year I read all the Game of Thrones books.

The first three of those were the best and I thought definitely better than the TV show, although its pretty good too even if a bit violent for my taste.

My reading lately has been leaning more towardbooks about human transformation of various kinds including non-fictional works.

This reading has come to constitute, I realized, a somewhat electric mix with the common thread of science (and in particular genetics and biology) fantasy becoming reality. I recommend these as thought-provoking reads.

See any patterns there?

This reading is in part inspired by research I was doing for my own new book GMO Sapiens, hopefully coming out in December. By the way GMO Sapiens is a mashup (or portmanteau) of Homo sapiens and GMO.

It is focused on human genetic modification and the very real possibility of designer babies on the horizon.

In the coming weeks and months I will be posting excerpts from the book. Stay tuned.

Theres a growing stream of stem cell good news of late.

Stem cell biotech, TiGenix, reported encouraging Phase 3 allogeneicresultson stem cells. Abig milestone. I cant wait to see the actual data. Its product, Cx601, has so far beensafe and effective forperianal fistulas inCrohns disease. See more from Alexey on this.

CIRM has fundedthe largest public stem cell bank in the world. Want to make a withdrawal?

Asterias reported some great news. Its AST OPC-1 product showed some signs of encouraging efficacy in the first three patients treated. They are hoping to expand the trial.

In about two weeks on September 16th, the first winner of the new Ogawa-Yamanaka Stem Cell Prize will be announced at Gladstone Institutes. This should be a very exciting event honoring a top stem cell translational innovator in the area of cellular reprogramming, who will also received a cash prize of $150,000. According to the organizers, The Prize was established through a generous gift from Hiro Ogawa to honor the memory of Betty Ogawa, who passed away in May 2014. It continues the philanthropic legacy she shared with her husband of 46 years. The prize also recognizesShinya Yamanaka too of course.

Any guesses on who will win? Let us knowin the comments. Any kind of recognition of achievement and innovation in stem cells is wonderful.

On that note, Im also starting to think about candidates for my own stem cell prize, the annual Stem Cell Person of the Year Award.Its not to the same scale with a $2,000 prize, but I fund it out of my own pocket. The focus is different too. My award goes to the person who has had the single strongest, most innovative impact in the stem cell world for a given year and has taken risks either scientifically or in the area of advocacy. Im looking for outside-the-box thinkers and doers.

Past winners have included super patient advocateRoman Reed,scientist and politicianElena Cattaneo(who went on to win the ISSCR Public Service Award), and this past year, pioneering stem cell translational scientistMasayo Takahashi. Dr. Takahashi might be a good bet to win the Ogawa-Yamanaka Prize this year.

Who should be nominated this year for the 2015 Stem Cell Person of the Year Award?

Its not too soon to let me know your thoughts even though nominations dont officially open quite yet. Last year we had more than two-dozen amazing nominees. The process includes an Internet vote to choose finalists and then I pick the winner from those, sometimes consulting privately with global stem cell scholars.

For the past few years post-publication peer review (PPPR) has grown in influence and one particular website, PubPeer, has become the primary go-to place specifically for bluntPPPR. The kind that happens in journal clubs in labs across the world. Comments on PubPeer have led to numerous serious corrections and retractions of flawed articles. Im most familiar with its role in the STAP cell case.

Both the founders of and most of the commenters on PubPeer have remained anonymous.

That is until today.

The founders of PubPeer have publicly identified themselves in a blog post and formed a new non-profit organization, The PubPeer Foundation.

PubPeer founders include Brandon Stell, George Smith and Richard Smith. Also with the founders on the PubPeer Foundation Board of Directors will be Boris Barbour and Gabor Brasnjo.

Who are these guys?

RetractionWatch (big HT to them) has an interesting interview with PubPeer founder Stell. I highly recommend reading it. Jennifer Couzin-Frankel over at Science also has a nice piece on this development.

Stell is a neuroscientist and Co-Team Leader at the Brain Physiology Lab in Paris, the source of his picture above.

I was trying to learn more about the other two founders, George Smith and Richard Smith. From Couzin-Frankels piece it appears that the brothers want to remain relatively out of the limelight, and their very common names may very well aid them in that. Couzin-Frankel does write that Richard was a grad student who briefly worked in Stells lab and George is a web developer.

As to the Foundation, RetractionWatch has a helpful quote from Stell on looking ahead:

What role do you hope PubPeer plays moving forward? What plans do you have for the Foundation?

We hope that the PubPeer Foundation will provide us with more opportunities to develop the site in ways that will help grow the community of post-publication peer reviewers and further encourage quality science.As more of us scientists become accustomed to commenting on papers, and as that becomes more of a part of the overall scientific process, I think well be able to finally up-end the backwards reward structure that is currently in place in science. Hopefully we can get to a point where the data are much more important to a scientists career than the journal that published them.

To form the PubPeer Foundation, the leaders could not remain anonymous. It seems like a good thing that the founders of PubPeer have identified themselves. They deserve a lot of credit for having had a transformative impact on how science corrects itself. Theyve also faced tough situations such as being sued by Fazlul Sarkar, a case that is still working its way through the legal system. Sarkar wants to know the identity of some anonymous PubPeer commenters. I predict that the PubPeer Foundation will now receive substantial financial support, which in part can be used to get legal assistancefor possible future challenges.

PubPeer has grown quickly, now has a striking following with around 300,000 pageviews/month and contains 35,000 total comments.

I recently chatted with Sean Morrison, current President of ISSCR, on his goals for the Society, where the stem cell field stands today, top challenges, and the future.

What are your goals for your tenure as President of ISSCR?

SM:ISSCR is the international voice for research in the scientific community. Theres been less effort though amongst policy makers and the general public. I want to expand the reach beyond just the scientists. ISSCR will be building its capacity to participate in stem cell policy issues worldwide and also its capacity to communicate with the public.

Whats the plan to make this happen?

SM: A range of things. Beefing up ISSCR communications programs. Blogging, twitter and other efforts.

What are the main challenges & opportunities that ISSCR faces now?

SM:ISSCR has had steady and remarkable growth. It has grown and its scope has grown too. Managing the growth is a challenge. Prioritizing future opportunities. How can we have the most impact for the membership? How can we grow that impact? The annual meeting continues to grow. International ISSCR symposia have grown. Publishing activities have expanded including withCell Stem Cell and nowStem Cell Reports. We continue to expand those kinds of activities. There is a set of opportunities related to going beyond the science. Our mission is to improve human health through stem cells. We cant do that solely by meetings and publishing. Those are critical core activities, but theres more that we can do such as in industry. Reaching out to those stakeholders. Expanding the activities of the Global Advisory Council (philanthropists, Susan Lim, and Deepak), stem cell policy, and communication.

How can ISSCR bring in more industry people?

SM: I do think more involvement of industry is important. How best can we do that? I attended the Industry Committee meeting at ISSCR meeting in Stockholm, where we had that conversation. I really do hope that we can increase the attractiveness and value provided by the annual meeting to people in industry. We want people talking about exciting unpublished data. One difficulty comes up though in this regard: who from industry is willing to talk about unpublished data? Some people have shown up in the past and are not willing to talk about data. The program committee needs to address that.

Whats your view on the evolution of the IPSC subfield?

SM: Im excited about stem cells generally. We need all kinds of stem cell research to move forward. Historically weve not been very good at predicting which cell type will work. Im very excited about somatic stem cell research and pluripotent stem cells, both embryonic and IPSC. Look at the things going on at Shinyas institute. Theyve been bold at diverse ways that they can have impact. With each year that goes by, the more plausible scenarios arise for possible therapies using pluripotent stem cells.

The pioneering IPSC trial in Japan was put on hold. How serious is that?

SM: If youve been culturing cells, some of the time theres going to be mutations. The fact that they found the mutations says that the process that they have in place worked. Its not uncommon in clinical trials for things to go on hold. Its not unique to stem cell trials or IPSCs. I have every expectation that theyll get that back on track.

What are you most excited about with your own research?

SM: Were doing a lot of work to characterize the HSC niche. Weve now identified the cells that are sources of the key factors for stem cell maintenance. In many ways the hematopoietic system is a paradigm. This will allow us to understand at a single cell level how the niche works and look for novel growth factors. Each time we identify one of those it has the potential to provide new tools.

What do you see as the most important and exciting stem cell development or trend of 2015 so far?

SM: Were at an inflection point in terms of stem cell therapies moving into high-quality clinical trials. In 2008 when we were fighting the public policy battles about where the line should be drawn on ESC research. Also there were people making claims about difficult problems. I was skeptical at the time. I felt that a lot of the problems could be too biologically complicated for cell therapies to work. Yet the science has surged forward much more quickly. Theres really exciting preclinical data and actual clinical trials that are about to start or have started. Spinal cord. Macular degeneration. And others. Some people have spent 10-20 years trying to understand the biology. Parkinsons with Lorenz Studer. Cell therapy for heart disease with Chuck Murry. Its important for the general public to understand the timeframe and that some will fail. In the past some were just squirting cells into tissuessort of like buying a lottery ticket. People now understand the biology better. Now we have a rational chance of success.

The debate that is shaping up for CIRM is also very important now. Stem cell research is already delivering and theres opportunity looking ahead. More funding for CIRM makes sense and it would be a major setback to not do that, especially with declining federal funding. One thing that will distinguish the winning states from the losing states is who has the vision to keep the biomedical research enterprise going at the state level. The conversation changed with CIRMs birth. It became, How do we keep up with California?

The spread of stem cell clinics selling non-FDA approved offerings in the US has accelerated. What should ISSCR and individual stem cell scientists be doing to address this growing problem?

SM: Theres a lot that youve done and we appreciate that. Theres also a lot that ISSCR has done. We have our A CloserLook website. ISSCR has spoken out more on this topic than any other topic relevant to the general public. Although stem cell research has enormous promiseand this is the most exciting time that weve ever hadunfortunately most people in the general public dont understand how long it takes to go from the idea or proof of principle in a mouse to do it in humans. Sadly there are fraudulent people out there that are preying on patients. These are at best unproven and in many cases not even plausible therapies.

Where do you see the stem cell field in 5-10 years?

SM:We should be excited, but Im always wary of these kinds of predictions. If we look over the last 10 years theres been a lot of twists in the plot. Theres been both good news and bad news. Some things have surged forward more quickly and some things that we are most excited about now werent on our radar screens then. We dont really know where were going to be. But Im very optimistic. The thing that we have to remember that we always forget, even when we identify an idea that works, it takes a lot of years to get that to a patient. Look how long it took for bone marrow transplant to develop. We now talk about bone marrow transplant as an example but it took 14 years. We should bear in mind that even if some of the things now in clinical trials are correct, it could take years to develop them in a safe and efficient way.

By offering unproven therapies, a Texas biotechnology firm has sparked a bitter debate about how stem cells should be regulated. David Cyranoski 13 February 2013 Ann McFarlane is losing faith. In the first half of 2012, the Houston resident received four infusions of adult stem cells grown from her own fat. McFarlane has multiple sclerosis (MS), and had heard that others with the inflammatory disease had experienced improvements in mobility and balance after treatment. The infusions which have cost her about US$32,000 so far didnt help, but she knew that there were no guarantees. It is McFarlanes experience with Celltex Therapeutics, the company that administered the cells, that bothers her. She was told

Its official: stem cells are drugs. At least, thats the opinion of the US district court in Washington DC, which has ruled that the Food and Drug Administration (FDA) has the authority to regulate clinics offering controversial stem cell therapies. Treatments in which stem cells are harvested from bone marrow and injected straight back into the same patient are deemed part of routine medical practice not regulated by the US government. But if the cells are subjected to more than minimal manipulation, the FDA maintains that the therapy becomes a drug, which must be specifically approved for use. It was on this basis that in 2008 the FDA began moves to shut downRegenerative Sciences,

Animal trials of Mesoblasts (ASX:MSB) mesenchymal stem cells in rheumatoid arthritis (RA) have encouraged the company press on with an FDA application for a phase II trial. Mesoblast (ASX:MSB) is continuing to expand the applications for its off-the-shelf stem cell technology by pushing forward to conduct a phase II trial for rheumatoid arthritis (RA). This follows encouraging results from preclinical trials of its adult stem cells in animal models of RA. The company revealed that a single injection of its mesenchymal precursor cells (MPCs) was able to simultaneously inhibit multiple cytokines responsible for driving RA. The MPCs concomitantly affected T cells, monocytes and synoviocytes to shut down TNF-alpha, IL-6 and IL-I7 cytokine pathways in sheep

The FDA requires the use of a Good Manufacturing Practice (GMP) facility for taking stem cell-based therapies into clinical trials. This GMP facility is a clean-room laboratory that ensures the therapeutic products will be safe and contamination-free for patients. In Spring 2008, CIRM gave $272 million for the construction of twelve stem cell research facilities in California. The University of California, Davis was one of the recipients of this Major Facilities grant. Their $20 million award is supporting construction of the new Institute for Regenerative Cures.

My laboratory is studying the molecular basis of pathogenesis of bacterial species, Borrelia burgdorferi, Treponema pallidum and Pseudomonas aeruginosa. These clinically important bacterial pathogens are transmitted to humans using different mechanisms and also show different disease manifestations. B. burgdorferi is transmitted by Ixodes tick vector, T. pallidum by sexual contact and P. aeruginosa, a ubiquitously present organism, is transmitted through ventilation or by direct contact of the patient with the contaminated source.

B. burgdorferi, a spirochete, is causative agent of Lyme disease, a multisystemic illness that affects various organs including joints, heart, nervous system and skin. If untreated, it may result in chronic disease with the symptoms including arthritis, acrodermatitis or neuroborreliosis. It is an extracellular pathogen often found adhering to the host cells in the biopsy specimens of the patients. We have been studying the molecular mechanisms involved in the attachment of Lyme disease spirochetes to a variety of host cells. The specific interaction between the spirochete and host cells may be responsible for the tissue tropism exhibited by B. burgdorferi. Our objective is to understand whether different B.burgdorferi adhesins show affinity for different host receptors on various host cells. We use genetics, biochemical techniques and tissue culture system to identify and characterize the bacterial and host molecules involved in this interaction in vitro. We have already identified two types of glycosaminoglycan receptors on mammalian cells that are recognized by several B. burgdorferi proteins and we are further characterizing this interaction. Mouse is a natural host of B. burgdorferi and C3H mice show several manifestations of Lyme disease observed in humans. We have recently adapted firefly luciferase-based detection system for B. burgdorferi. Using a combination of bioluminescent B. burgdorferi and mouse model of infection, we will further analyze the contribution of each bacterial ligand-host receptor interaction in Lyme pathogenesis. Tissue colonization by the spirochetes will be monitored non-invasively by employing in vivo imaging system. Recently, we have initiated studies to understand molecular basis of T. pallidum pathogenesis using this as a surrogate system.

P. aeruginosa is an opportunistic pathogen and produces a wide variety of virulence factors. It results in a variety of illnesses and is responsible for high morbidity and mortality in immunocompromised and elderly patients. Due to a highly adaptable nature of P. aeruginosa and its ability to survive even in detergents, it is a major contributor to infections in the hospital environment. We have been studying the quorum-sensing mediated induction of several virulence factors in this organism both as free-living organism and in association with its different hosts. We will assess the role of selected virulence factors in biofilm formation while P. aeruginosa is present in communities along with the other organisms. Our current focus is to investigate genetics of production and regulation of PrpL protease and pyocyanin pigment of P. aeruginosa and examine the roles of these virulence factors in tissue destruction. The roles of these two virulence factors in corneal damage, in burn wounds and in the cystic fibrosis patients will then be examined.

How does gene therapy work? – Genetics Home Reference

Posted: September 2, 2015 at 8:42 pm

Gene therapy is designed to introduce genetic material into cells to compensate for abnormal genes or to make a beneficial protein. If a mutated gene causes a necessary protein to be faulty or missing, gene therapy may be able to introduce a normal copy of the gene to restore the function of the protein.

A gene that is inserted directly into a cell usually does not function. Instead, a carrier called a vector is genetically engineered to deliver the gene. Certain viruses are often used as vectors because they can deliver the new gene by infecting the cell. The viruses are modified so they cant cause disease when used in people. Some types of virus, such as retroviruses, integrate their genetic material (including the new gene) into a chromosome in the human cell. Other viruses, such as adenoviruses, introduce their DNA into the nucleus of the cell, but the DNA is not integrated into a chromosome.

The vector can be injected or given intravenously (by IV) directly into a specific tissue in the body, where it is taken up by individual cells. Alternately, a sample of the patients cells can be removed and exposed to the vector in a laboratory setting. The cells containing the vector are then returned to the patient. If the treatment is successful, the new gene delivered by the vector will make a functioning protein.

Researchers must overcome many technical challenges before gene therapy will be a practical approach to treating disease. For example, scientists must find better ways to deliver genes and target them to particular cells. They must also ensure that new genes are precisely controlled by the body.

A new gene is injected into an adenovirus vector, which is used to introduce the modified DNA into a human cell. If the treatment is successful, the new gene will make a functional protein.

The Genetic Science Learning Center at the University of Utah provides information about various technical aspects of gene therapy in Gene Delivery: Tools of the Trade. They also discuss other approaches to gene therapy and offer a related learning activity called Space Doctor.

The Better Health Channel from the State Government of Victoria (Australia) provides a brief introduction to gene therapy, including the gene therapy process and delivery techniques.

Human beings have cells with 46 chromosomes -- 2 chromosomes that determine what sex they are (X and Y chromosomes), and 22 pairs of nonsex (autosomal) chromosomes. Males are "46,XY" and females are "46,XX." The chromosomes are made up of strands of genetic information called DNA. Each chromosome contains sections of DNA called genes, which carry the information needed by your body to make certain proteins.

Each pair of autosomal chromosomes contains one chromosome from the mother and one from the father. Each chromosome in a pair carries basically the same information; that is, each chromosome pair has the same genes. Sometimes there are slight variations of these genes. These variations occur in less than 1% of the DNA sequence. The genes that have these variations are called alleles.

Some of these variations can result in a gene that is abnormal. An abnormal gene may lead to an abnormal protein or an abnormal amount of a normal protein. In a pair of autosomal chromosomes, there are two copies of each gene, one from each parent. If one of these genes is abnormal, the other one may make enough protein so that no disease develops. When this happens, the abnormal gene is called recessive, and the other gene in the pair is called dominant. Recessive genes are said to be inherited in an autosomal recessive pattern.

However, if only one abnormal gene is needed to produce a disease, it leads to a dominant hereditary disorder. In the case of a dominant disorder, if one abnormal gene is inherited from mom or dad, the child will likely show the disease.

A person with one abnormal gene is called heterozygous for that gene. If a child receives an abnormal recessive disease gene from both parents, the child will show the disease and will be homozygous (or compound heterozygous) for that gene.

GENETIC DISORDERS

Almost all diseases have a genetic component. However, the importance of that component varies. Disorders in which genes play an important role (genetic diseases) can be classified as:

A single-gene disorder (also called Mendelian disorder) is caused by a defect in one particular gene. Single gene defects are rare. But since there are about 4,000 known single gene disorders, their combined impact is significant.

Single-gene disorders are characterized by how they are passed down in families. There are six basic patterns of single gene inheritance:

The observed effect of a gene (the appearance of a disorder) is called the phenotype.

In autosomal dominant inheritance, the abnormality or abnormalities usually appear in every generation. Each time an affected woman has a child, that child has a 50% chance of inheriting the disease.

People with one copy of a recessive disease gene are called carriers. Carriers usually don't have symptoms of the disease. But, the gene can often be found by sensitive laboratory tests.

In autosomal recessive inheritance, the parents of an affected individual may not show the disease (they are carriers). On average, the chance that carrier parents could have children who develop the disease is 25% with each pregnancy. Male and female children are equally likely to be affected. For a child to have symptoms of an autosomal recessive disorder, the child must receive the abnormal gene from both parents. Because most recessive disorders are rare, a child is at increased risk of a recessive disease if the parents are related. Related individuals are more likely to have inherited the same rare gene from a common ancestor.

In X-linked recessive inheritance, the chance of getting the disease is much higher in males than females. Since the abnormal gene is carried on the X (female) chromosome, males do not transmit it to their sons (who will receive the Y chromosome from their fathers). However, they do transmit it to their daughters. In females, the presence of one normal X chromosome masks the effects of the X chromosome with the abnormal gene. So, almost all of the daughters of an affected man appear normal, but they are all carriers of the abnormal gene. Each time these daughters bear a son, there is a 50% chance the son will receive the abnormal gene.

In X-linked dominant inheritance, the abnormal gene appears in females even if there is also a normal X chromosome present. Since males pass the Y chromosome to their sons, affected males will not have affected sons. All of their daughters will be affected, however. Sons or daughters of affected females will have a 50% chance of getting the disease.

EXAMPLES OF SINGLE GENE DISORDERS

Autosomal recessive:

X-linked recessive:

Autosomal dominant:

X-linked dominant:

Only a few, rare, disorders are X-linked dominant. One of these is hypophosphatemic rickets, also called vitamin D -resistant rickets.

CHROMOSOMAL DISORDERS

In chromosomal disorders, the defect is due to either an excess or lack of the genes contained in a whole chromosome or chromosome segment.

Chromosomal disorders include:

MULTIFACTORIAL DISORDERS

Many of the most common diseasesare caused byinteractions of several genes and factors in the the environment (for example, illnesses in the mother and medications). These include:

MITOCHONDRIAL DNA-LINKED DISORDERS

Mitochondria are small organisms found in most of the body's cells. They are responsible for energy production inside cells. Mitochondria contain their own private DNA.

In recent years, many disorders have been shown to result from changes (mutations) in mitochondrial DNA. Because mitochondria come only from the female egg, most mitochondrial DNA-related disorders are passed down from the mother.

Mitochondrial DNA-related disorders can appear at any age. They have a wide variety of symptoms and signs. These disorders may cause:

Some other disorders are also known as mitochondrial disorders, but they do not involve mutations in the mitochondrial DNA. These disorders are usually single gene defects and they follow the same pattern of inheritance as other single gene disorders.

What are genes?

Genes are the part of a body cell that contain the biological information that parents pass to their children. Genes control the growth and development of cells. Genes are contained in DNA (deoxyribonucleic acid), a substance inside the center (nucleus) of cells that contains instructions for the development of the cell.

You inherit half of your genetic information from your mother and the other half from your father. Genes, alone or in combination, determine what features (genetic traits) a person inherits from his or her parents, such as blood type, hair color, eye color, and other characteristics, including risks of developing certain diseases. Certain changes in genes or chromosomes may cause problems in various body processes or functions.

Many genes together make up larger structures within the cell called chromosomes. Each cell normally contains 23 pairs of chromosomes.

A human has 46 chromosomes (23 pairs). One chromosome from each pair comes from the mother, and one chromosome from each pair comes from the father. One of the 23 pairs determines your sex. These sex chromosomes are called X and Y.

Some genetic disorders are caused when all or part of a chromosome is missing or when an extra chromosome or chromosome fragment is present.

Genetic testing examines a DNA sample for gene changes, or it may analyze the number, arrangement, and characteristics of the chromosomes. Testing may be performed on samples of blood, semen, urine, saliva, stool, body tissues, bone, or hair.
