Suzanne Barbour, a biochemist and national leader in graduate education, has been appointed dean of The Graduate School and vice provost for graduate education, Provost Sally Kornbluth announced Monday. Barbour will also hold a faculty appointment in the Duke University School of Medicine.

Barbour will be responsible for ensuring the excellence of Dukes graduate programs, leading long-term strategic planning for graduate studies, and managing The Graduate Schools work that supports students and faculty throughout the university.

The Graduate School oversees Dukes 55 Ph.D. programs, 29 of the universitys masters programs, and a number of graduate certificates and dual and joint degrees. It collaborates with Dukes other schools, academic departments, and various campus services to support about 3,500 graduate students in areas such as academics, admissions, financial aid, professional development, and wellbeing.

Barbour will join Duke Sept. 15, succeeding Paula D. McClain, who has served as dean and vice provost for graduate education since 2012.

Suzanne has a tremendous record of advancing graduate education and graduate student success, and I am delighted to welcome her to Duke, Kornbluth said.

Barbour has been at the University of North Carolina at Chapel Hill since 2019, serving as dean of The Graduate School and professor of biochemistry and biophysics. At UNC, she has led efforts to increase student access and inclusion, foster experiential professional development opportunities for students pursuing non-academic career paths and improve mentoring for graduate students. Under her leadership, The Graduate School has surpassed its goal of raising $10 million as part of the Campaign for Carolina.

In addition to serving students, faculty and staff on campus, Dukes Graduate School has made many important contributions that have impacted graduate education at the national level, Barbour said. I am grateful for the opportunity to join the talented, innovative and committed team that has made this possible, and I look forward to collaborating with Dukes faculty, staff and students to further this important work.

Prior to her appointment at UNC, Barbour served as dean of the University of Georgia Graduate School for four years, overseeing 250 graduate programs. She has also held appointments as a program director at the National Science Foundation and as a faculty member and graduate program director at Virginia Commonwealth University. Barbours research in the field of lipid biochemistry has focused on the role of iPLA2 and lipids generated downstream of the enzyme in cellular signaling, in mammalian cell models.

Suzanne has distinguished herself through her leadership of the graduate schools at UNC and the University of Georgia, and through her sustained commitment toexcellence in all aspects ofgraduate education, including a commitment to diversity, equity and inclusion in the graduate student population, Kornbluth noted. I look forward to working with her to support graduate education and graduate students.

Barbours appointment follows a national search chaired by Craig Henriquez, professor of biomedical engineering, and conducted by a committee of Duke faculty and representatives of the Graduate School Board of Visitors and graduate student body.

I am grateful to the search committee for their work throughout this process, as well as to Craig Henriquez for his service as chair, Kornbluth said.

Barbour is active nationally as a member of the Board of Directors of the Council of Graduate Schools, the National Science Foundations Committee for Equal Opportunities in Science and Engineering and its Directorate for Biological Sciences Advisory Committee, the governing council of the American Society for Biochemistry and Molecular Biology, and the Graduate Education Advisory Council of the Educational Testing Service.

Over the next five years, the University of Cincinnatis College of Medicine is creating a cool cutting-edge space to study the images of life.

The way the Center for Advanced Structural Biology (CASB) will do that is through cryo-EM, or electric microscopy. This structural biology methodology gained a lot of attention following the 2017 Nobel Prize awards for chemistry. Cryo-EM is valuable for studying any kind of proteins that are related to any kind of human disease.

Announcement of the Nobel Prize in Chemistry 2017

Researchers can prepare and image samples at very cold temperatures to visualize them in a near-native hydrated state. This helps them get a look at proteins at the atomic level.

Were actually visualizing a single protein, says Rhett Kovall, Ph.d., of the Department of Molecular Genetics, Biochemistry and Microbiology, who has helped get the funding and plan the cryo-EM facility in the CASB. This is quite different from other structural techniques where you dont get this direct visualization.

For research scientist and facility manager Desiree Benefield, Ph.d., its valuable for studying any kind of proteins that are related to human disease. She first learned about cryo-EM in graduate school.

I just fell in love with it because you could actually see the science, she says. It wasnt a clear liquid in a tube or a band on a gel you were looking at your question, which is really exciting to me.

The samples are flash-frozen with a Vitrobot (specimen preparation unit) and then scientists study them on the Talos L120C Transmission Electron Microscope. In this video, Benefield shows how it all works.

The $1.5 million to buy the equipment came from Research 2030 as part of a JobsOhio grant.

Eventually, Cincinnati Childrens Hospital, the University of Kentucky and Miami University will have access to UCs equipment.

When the virus that causes COVID-19 enters the body, it hijacks cellular proteins and suppresses the human inflammatory response, allowing the virus to spread. University of Florida researchers have discovered a novel way in the lab to fight rapidly evolving strains of coronaviruses by breaking that cycle.

The group created a molecular decoy that blocks two proteins coronaviruses use to evade a normal immune system response. Blocking these proteins prevents the virus from taking hold within human cells, the researchers found. During early tests, short chains of amino acids, known as peptides, inhibited the replication and release of two coronaviruses including SARS-CoV-2. The findings werepublished recently in the journal Frontiers in Immunology.

The UF teams compounds dont attack coronaviruses directly, said Alfred S. Lewin, Ph.D., a professor ofmolecular genetics and microbiology in the UF College of Medicine.

These peptides have the potential to allow our immune system to fight off the virus more effectively, Lewin said.

To establish their findings, the researchers focused on two coronaviruses. One is a seasonal virus that causes upper-respiratory infections like the common cold. Researchers at UF and elsewhere already knew that people with antibodies to it were less likely to develop serious COVID-19 infections.

That potential benefit intrigued Chulbul M. Ahmed, Ph.D., a research assistant professor of molecular genetics and microbiology. Their team developed a peptide known as pJAK2. During testing on human cells, the compound significantly reduced the viruses concentrations and ability to replicate. In SARS-CoV2, the peptide reduced the viruss replication more than tenfold, the researchers found. The cell-penetrating peptides work by acting as a decoy and suppressing two proteins that would otherwise allow invading viruses to thrive.

When the peptide was combined with a second virus-inhibiting protein, viral activity was inhibited even further than with either peptide treatment alone.

A future COVID-19 therapy based on pJAK2 intrigues the researchers for several reasons. It can be synthesized easily and in large quantities at a reasonable cost, Ahmed said. And it has natural origins as a cell-penetrating form of 13 amino acids already found in humans.

The case to be made here is that were not dealing with a foreign substance. Its something that the human body already produces in some form, Ahmed said.

The researchers believe pJAK2 would be most useful as an early-stage therapy that fights the SARS-CoV-2 virus by stimulating an immune response. Several antiviral drugs to treat COVID-19 in its early stages are already on the market, including the well-known remdesivir.

This would be a potentially useful treatment for someone with an early or intermediate-stage infection but certainly not for someone who already has a serious inflammatory response to the virus, Lewin said.

The discovery may also prove to be a preventive treatment for COVID-19, Ahmed said. Testing on the influenza virus revealed both therapeutic and preventive qualities. Ahmed said its reasonable to believe those same characteristics could apply to SARS-CoV-2 and its variants as well as other viruses that lead to herpes, Ebola, the flu and monkeypox.

For influenza, we have shown that it acts both as a prophylactic as well as a therapeutic compound. So this could potentially be given to uninfected family members and primary contacts of the affected individuals to protect them from getting a more serious form of SARS-CoV-2, Ahmed said.

Next, the researchers want to fully test their findings in primary human lung cells before moving to experiments in mouse models and eventually human clinical trials.

Research collaborators included Tristan R. Grams, Ph.D., a Ph.D. candidate in biomedical sciences; David C. Bloom, Ph.D., a professor and chair of the College of Medicines department of molecular genetics and microbiology; and Howard M. Johnson, Ph.D., an emeritus faculty member of the UF department of microbiology and cell science. Research funding was provided by the Shaler Richardson Professorship endowment, Research to Prevent Blindness and multiple National Institutes of Health grants.

Genetic testing has afforded oncologists with the opportunity to identify patients who may have a higher risk of developing cancer at some point in their life, especially for patients with a predisposition for certain cancers and patients who may have family members with cancer. Additionally, genetic testing to identify actionable mutations has allowed patients to receive targeted therapy and have their long-term treatment plan mapped out at diagnosis, according to Lee S. Schwartzberg, MD, FACP.

However, this testing has created a vast amount of information to digest for each patient, and streamlining platforms to pull more relevant information together will be important as the genetic testing field continues to grow, Schwartzberg said.

Linking the germline genetics with outcomes, like the ancestry data, is becoming increasingly interesting, Schwartzberg said. We want to know if patients who have a specific ancestry might have a predisposition for multiple genes interacting to get a cancer, or, more importantly, how the outcome [of] that cancer might differ.

In an interview with OncLive, Schwartzberg, the chief of Medical Oncology and Hematology at the Renown Institute for Cancer, and a professor of clinical medicine at the University of Nevada, discussed barriers to genetic testing in oncology, the role of a molecular tumor board, and the expanding number of platforms available to perform testing.

Schwartzberg: When discussing genetic testing in oncology, were talking about 2 broad themes. The first is germline testing, which has been available for about 25 years and should be considered for patients who typically have family history [of cancer] or meet the criteria for germline testing. These criteria have evolved dramatically over time to multi-panel testing. We usually test multiple genes that we now know increase the susceptibility to cancer. We test individuals with a diagnosis of cancer and potentially their family members if an alteration, a pathogenic variant, or a probable pathogenic variant [is found] in the germline. We also test high-risk individuals when they dont have cancer.

The barriers include finding the right patients to test. It is easy for oncologists, if you have a patient with a cancer diagnosis, to determine, based on their family history or the type of cancer they have, or both, whether germline testing should be considered. Those guidelines have evolved dramatically over the past few years and include patients that have strong family histories. We have therapeutic drugs for patients with certain germline alterations, namely PARP inhibitors, particularly in patients with breast cancer. That has led to a broader discussion of testing where we believe that the majority of patients with breast cancer should be tested and not miss an opportunity to receive a PARP inhibitor in the adjuvant setting if they have higher-stage disease.

One of the barriers in the space can be insurance in some cases, [when it needs to be determined] whether patients fall into NCCN [testing] guidelines. Making sure that the high-risk patients are identified by their primary care physicians for testing [is necessary]. Many times, oncologists end up doing the testing or arrange with a genetic counselor to do testing. But we can only do the testing if were aware of those patients.

There is still a gap in access to patients who may benefit from testing [even though] there may be a strategy of drug therapy, imaging, or more intensive surveillance, which can be an issue. The second issue with germline testing is interpretation of the results. In other words, not finding the patients is one issue, but finding patients to test and misinterpreting the results is another issue. We see this frequently, particularly with people with too much to do, such as primary care doctors. Its too much to stay [up-to-date] on everything with the vast breath of what they see.

Particularly when patients get a variant of unknown significance in a cancer susceptibility gene, occasionally, those patients will be counseled to undergo prophylactic surgery or increased surveillance. That is not the recommendation for a variant of unknown significance. Understanding the difference between a pathogenic or likely pathogenic variant vs a variant of unknown significance [is important], and we need to get the word out. Primary care doctors, oncologists, and surgeons [need to be educated].

The way to avoid the pitfall is to have a high-risk clinic for patients who might be susceptible to breast and ovarian cancer, for example. Increasingly, we recognize that there are other patients [who may benefit from testing]. The simple thing is to acknowledge that a comprehensive family history is taken. For people who dont have cancer, thats where you find the gold. If you have families that have multiple cancers that fall into a pattern of potentially suggesting a hereditary predisposition gene, thats where you make that recognition and send them to the appropriate person if youre not equipped to do the testing. That can be for primary care physicians, but it can be for oncologists, as well. Taking that family history is really important.

[It is important to have] electronic platforms that help on the genetic side and hereditary side to complete the family history and clinical decision support that will highlight and identify a patient who might be a good candidate for multi-gene panel testing in the germline. We are also seeing that the awareness of clinical decision support and the integration of results into the electronic record is important for patients who have cancer where we do a comprehensive genomic profile.

For about 10 years, weve had the ability to do multi-gene panels that have grown in size, and they now typically run anywhere from several hundred genes to whole exome and whole transcriptome sequencing. This includes both DNA and RNA at one end, and, at the very least now, we have the ability to do genomic profiling of multiple genes, including the actionable genes. That delivers a tremendous amount of information.

A barrier there includes reimbursement. There are large payers who are not yet convinced of the broad-scale benefit of doing comprehensive genomic profiling in advanced cancers across the board. [For example], in many of the guidelines, including nonsmall cell lung cancer [NSCLC], comprehensive genomic profiling is recommended, as opposed to doing individual tests for the actionable genes. Given the fact that [NSCLC] now has upward of 10 actionable alterations, even in the first-line setting, its critical to know that information up front. Payers are still requiring that the sequential single-gene approach be taken. I believe thats wrong.

Going beyond to other diseases like breast cancer, where you might not make a treatment decision in the first line based on a comprehensive genomic profile, I strongly believe in having that information at hand when starting to plot out the different courses of therapy that a patient may have during their lifetime with advanced breast cancer. Its good to have that information before you have to make the decision in a situation when a patient progresses. There are also many rare cancers that have specific alterations, and they should be tested, which can have a huge effect on outcome.

I recommend doing comprehensive genomic profiling on patients at their diagnosis of advanced disease. Today, we can even follow them with liquid biopsies on a regular basis, although thats still in evolution in terms of the most valuable and impactful way to do that [in terms of improving] clinical outcome.

Another barrier is awareness [of knowing] if we should do comprehensive genomic profiling on all patients. Not all oncologists are doing that yet, even in NSCLC. Although it is ironclad that we should do it in all patients, only about 70% of patients with advanced NSCLC, up until the past year, receive comprehensive genomic profiling at diagnosis. That number should be closer to 90%. Although weve made steady progress over time, were not yet at the optimal level because of some of the other barriers.

Another barrier for genomic profiling is interpreting the results. We get a wealth of information, typically a 30- or 40-page report, when we do comprehensive genomic profiling from a blood or tissue sample. The amount of information is huge. The problem is, no one has the time to sit and read a 30-page report, word for word, so it does get summarized. However, many of the nuances can be lost in the summary. One way to get around that barrier is to have a molecular tumor board with a group of people that have familiarity with comprehensive genomic profiling, including genetic counselors, pathologists, molecular pathologists, clinical oncologists, and imagers, to go through the report.

If you get genes that look like you can do something with in terms of a therapy, it is important to present those in a real-time fashion and get the input of a tumor board, just like we would with a standard case without the genomics or the molecular findings. That can be done in a disease-specific tumor board, although it gets complicated there. Utilizing the molecular tumor board with the most impactful cases presented on a regular basis can be very useful for changing patients to the right therapy, for agreeing with the therapy, and, importantly, for [enrollment in] clinical trials. For directing patients to clinical trials, a molecular tumor board is fantastic. Whether its right at the time the patient gets testing or as a clinical decision support tool, every time a patient progresses and changes therapy, oncologists are reminded that this patient has a molecular alteration, and they may be a candidate for these current trials that are available. We are not quite yet at the sophistication of clinical decision support to do that, but we are getting closer. The idea that you can surface an alteration that would prompt the clinician to look for a clinical trial at the time of progression is coming along nicely. Its a great use of technology to avoid that barrier to best care.

Myriad Genetics is going in multiple directions to improve care through the combination of genetics, genomics, and developing new tools. The homologous recombination deficiency [HRD] score is something thats had a lot of attention. In this case, were looking at a variety of different genomic alterations, individual genes, and broader genome-wide [factors] such as loss of heterozygosity. In pulling those all together into an HRD score, we use that to make clinical decisions. This is most notably [applied] in ovarian cancer, but its starting to extend out into other diseases. Having that information in hand is really going to be critical in the future for making the right decision for therapy for these patients.

Another group of genomic testing includes genomic profiling, genomic expression, or genomic classifiers, which look at the pattern of expression of certain genes, then pulling them together into a model that predicts either prognosis or response to types of therapies. EndoPredict is a good example of that, with good data showing prognosis of patients, low to high, based on EndoPredict score. You can have a patient with a clinically high-risk tumor that has a genomically low-risk tumor, and you would treat that patient differently. Thats what the study gets at: How often do you use that kind of data to make a decision, or how does the test affect your decision making? That is important when you have genomic classifier tests that will tell you information thats both prognostic and predictive.

[Research is also being done with genetics and ancestry.] For example, Black women with triple-negative breast cancer have a worse outcome. Is any of that due to their ancestry in the sense of inheriting multiple genes? Not genes that are single actors, like BRCA, which has, as an individual gene, influenced the risk and outcomes of breast cancer, but how groups of genes that are inherited over generations might also affect that. That is an area of active discovery and research.

We are at the dawn of the age of how to best use liquid biopsies. One of the benefits of a liquid biopsy is that its simple, minimally invasive, and it can be repeated. As opposed to using tissue, liquid biopsy is a repetitive source of information about how a cancer is acting. The use of liquid biopsy is extremely wide ranging. On one end, were at the dawn of using liquid biopsy to do multi-cancer early detection, and the first test just rolled out where a tube of blood may be able to identify early-stage patients with a variety of different cancers. These tests are now out commercially, and much more research will be done to improve the sensitivity and specificity for the accuracy of these tests.

For the first time, we can think about screening patients for cancer beyond their traditional screening technologies. We can do it broadly, although the question remains if we can afford it as a society, and if insurance will pay to screen broad populations. The way its going to go, in my opinion, is the higher-risk populations will get access to these tests. There will be more impact in terms of the number of positives that are found, as opposed to the lower-risk groups.

This is exciting. Data that were presented at the 2022 ASCO Annual Meeting about minimal residual disease from liquid biopsy examined the sensitivity of liquid biopsies to pick up DNA or methylation patterns, [similar to] the multi-cancer early detection test. In patients who would be at risk after their initial tumor is removed, who are those patients that are destined to relapse? Can we intervene and do something about it early before they come in with symptoms or abnormal imaging? Thats a fascinating area, and its going to be one thats going to yield a lot of information over the next few years.

We can use liquid biopsies to monitor patients on therapy, to find early relapse, and [to detect] defined patterns of mutations that change over time. It gives us insight into the reasons for resistance. Sometimes, like in NSCLC, we can use liquid biopsies to see what the cause of resistance is and get patients on clinical trials for targeted therapies for new generations of treatments. That is a whole area that is exploding right now.
