IRP’s Eugene Koonin Elected to National Academy of Medicine

Scientist Decoded DNA to Build a Genomic Tree of Life

Wednesday, December 14, 2022

Dr. Eugene Koonin

In 1973, the geneticist Theodosius Dobzhansky wrote a now-famous essay that declared, “Nothing in biology makes sense except in the light of evolution.” That sentiment has served as the guiding principle for the career of IRP senior investigator Eugene V. Koonin, Ph.D., who was elected to the National Academy of Medicine (NAM) in October 2022 for his contributions to the field of evolutionary biology.

Dr. Koonin’s pioneering efforts to identify clusters of similar genes found in different organisms passed down by a common ancestor — known as ‘homologous’ genes — has helped to unlock the secrets encoded in DNA and create a foundation for the systematic study of how genes evolve and function. His lab at the National Library of Medicine’s National Center for Biotechnology Information (NCBI) uses a combination of genomic sequencing and mathematical modeling to compare genes across species and determine how they work and where they came from. From this information, his team can develop a systematic framework to show the relationship between genes as they evolved. It’s like drawing the tree of life, but on a genomic scale.

Friendly Virus Could Deliver Gene Therapy Under Immune System’s Radar

IRP Research Points to New Tool for Alleviating Genetic Disorders

Tuesday, December 6, 2022

antibodies combatting viral particles

With all the dangerous viruses out there, from the seasonal flu to the novel coronavirus that causes COVID-19, people understandably want to make sure their immune systems are topped-up with disease-fighting antibodies that block viral invaders. However, when it comes to the viruses scientists are modifying to deliver gene therapy, having a robust immune response is actually an obstacle to getting healthy. In a new study, IRP researchers showed that most people’s immune systems don’t react to a particular harmless virus that can effectively deliver new genes to the liver and heart, making it a promising delivery vehicle for therapies designed to alleviate a life-threatening genetic condition.

Simple Blood Test May Thwart a Complicated Cancer

Signs of Past Viral Exposure Predict Liver Cancer Risk

Monday, October 24, 2022

The liver has a difficult but important job. It serves as the central processing plant for all the food, drinks, and drugs we take in, separating and breaking them down into usable nutrients and toxic wastes that need to be removed from the body. It’s no surprise, then, that diseases affecting the liver can have life-threatening consequences. In particular, infections like hepatitis B and C and liver damage caused by alcohol, drugs, or fatty liver disease can all lead to liver cancer. Unfortunately, even though the presence of these conditions are harbingers of possible liver cancer, the disease often passes unnoticed until it is at an advanced, less treatable stage.

IRP senior investigator Xin Wei Wang, Ph.D., and his NIH research team are developing ways to detect liver cancers much earlier, when existing treatments are much more likely to stop their growth. In honor of Liver Cancer Awareness Month this October, I talked to Dr. Wang about his research and the novel blood test his lab has developed to predict liver cancer risk.

Teaming Up to Tackle Engineering Challenges

Innovation Awards Accelerate Development of New Research Techniques

Monday, September 19, 2022

Scientists spend years, even decades, intensely studying a specific disease or biological system, an approach that yields unrivaled knowledge. However, many important scientific questions require a deep understanding of several subjects. As a result, the IRP has numerous programs dedicated to encouraging scientists with different areas of expertise to work together.

One such program is the NIH Director’s Challenge Innovation Awards, which funds innovative, high-impact projects that require the cooperation of researchers in more than one of NIH’s Institutes and Centers. This year, the program selected six promising proposals with one foot in the disciplines of biology and medicine and another in engineering or the physical sciences.

Leading the Charge Against Infectious Disease

Government Awards Recognize H. Clifford Lane’s Four Decades of Research Achievements

Wednesday, July 27, 2022

Dr. H. Clifford Lane

The remarkable career of H. Clifford Lane, M.D., might have gone very differently if a NIH scientist hadn’t accidentally eavesdropped on Dr. Lane’s conversation with a colleague in 1979. After hearing Dr. Lane mention that he had missed the deadline to apply for a position at NIH, the NIH researcher made some calls and discovered a spot there had just opened up — one that was perfect for Dr. Lane, who would spend the ensuing decades conducting life-saving research to understand and combat some of the world’s most dangerous infectious diseases.

Now the Clinical Director at the National Institute for Allergy and Infectious Disease (NIAID), Dr. Lane has been named a finalist for the 2022 Samuel J. Heyman Service to America Medals’ Career Achievement Award in recognition of his crucial contributions to the fight against HIV/AIDS, Ebola, COVID-19, and other illnesses. Also known as the “Sammies,” the awards recognize federal employees who are “breaking down barriers, overcoming huge challenges, and getting results.”

Three-Minute Talks Showcase Smooth-Talking Scientists

IRP Researchers Engage and Educate at Competition Finals

Wednesday, July 13, 2022

Three-Minute Talks poster

English is generally considered the ‘international language of science,’ since nearly all scientific papers are published in English. Yet, even to a native English speaker, scientists seem to be using another language entirely to talk about their research. Most Americans, after all, don’t know an ‘autophagosome’ from a ‘lysosome’ and would be hard-pressed to explain the difference between an ‘oocyst’ and a ’sporozoite.’

Fortunately, efforts like NIH’s annual Three-Minute Talks (TmT) competition are helping scientists learn how to communicate about their research in a manner that is much easier to understand. On June 30, after months spent whittling down dozens of competitors from across the IRP, 10 finalists raced against the clock to explain their work and its importance in a clear and compelling way.

Postdoc Profile: From Bench to Bedside and Back Again

Dr. Stefan Barisic Turns Laboratory Discoveries into Kidney Cancer Treatments

Wednesday, June 22, 2022

Dr. Stefan Barisic

The Laboratory of Transplantation Immunotherapy sits at the heart of the NIH Clinical Center, just down the hallway from the Southeast inpatient unit. Here, IRP postdoctoral research fellow Stefan Barisic, M.D., labors at the bench with the goal of creating practical treatments for kidney cancer patients. Having such proximity to his patients was one of the chief attractions of working at NIH for Dr. Barisic.

“The NIH Clinical Center is an amazing place because it has all the resources you need to go from the bench to the bedside and back to the bench all in one building,” says Dr. Barisic.

Award Honors Promising Female Scientists

Women Scientists Advisors Select Three Young Researchers for Recognition

Thursday, May 19, 2022

Dr. Sally Chang

While women have now overtaken men in terms of admission and enrollment in undergraduate education, they remain underrepresented in the sciences. This includes at NIH, where 74 percent of senior investigators and 54 percent of tenure-track investigators are male, according to the most recent statistics available. Consequently, NIH is putting considerable effort into supporting women scientists at all stages of their careers.

One NIH entity dedicated to this important work is the NIH Women Scientists Advisors (WSA), a group of women elected to represent the interests of women scientists in the IRP. Among its many initiatives, each year the WSA chooses several female postdoctoral fellows or graduate students in the IRP to receive the WSA Scholar Award in recognition of their outstanding scientific achievements. The awardees present their research at the annual WSA Scholars Symposium, which this year was held on April 25 and recognized young women leading efforts to better understand how disease-related genes evolved, an investigation of how a fatty liver can give rise to liver cancer, and the evaluation of a way to deliver gene therapy for a rare genetic disease. Read on to learn more about this year’s WSA Scholars and the impressive discoveries they have made during their time in the IRP.

IRP Pushes Forward in Fight Against Pandemic Virus

Many NIH Labs Remain Focused on COVID Research

Monday, February 14, 2022

SARS-CoV-2 virus particles

Since the early days of the COVID-19 pandemic, IRP researchers have been hard at work learning about the virus and developing ways to prevent and treat infections. That research remains as important as ever, particularly as the new Omicron variant of the virus continues to spread rapidly.

Fortunately, NIH’s Intramural Targeted Anti-COVID-19 Program (ITAC) has been providing IRP scientists with millions of dollars to support their research on the pandemic virus, known as SARS-CoV-2. Last week, the “I Am Intramural” blog discussed ITAC-funded efforts to learn about the biology of the virus and how it affects the body. This week, we’ll look at IRP projects focused on ways to track, treat, and prevent infections.

IRP Scientists Continue Efforts to Quell Pandemic

COVID-19 Research at NIH Show No Signs of Slowing

Wednesday, February 9, 2022

SARS-CoV-2 virus particle

It’s been more than two years since the first outbreak of COVID-19 occurred in China. During that time, amazing scientific advances have dramatically altered prevention and treatment for the illness, including the development of remarkably safe and effective vaccines. However, even with widespread vaccination, scientists predict that the disease will continue to circulate in society indefinitely, with seasonal ebbs and flows like the flu.

As a result, even as COVID-19 vaccine shots rolled out by the hundreds of millions, numerous IRP researchers continued studying the disease and the virus responsible for it. Many of these projects have been funded by the NIH’s Intramural Targeted Anti-COVID-19 Program (ITAC), an initiative that provides IRP researchers with funding for research related to COVID-19. Over the past year and a half, ITAC has provided more than $12 million to support a wide variety of projects — more than can be covered in just one blog post. Read on to learn about just a handful of the many ways IRP researchers are contributing to the fight against COVID-19, and stay tuned next week for another blog describing even more ITAC-funded COVID research.
