Many scientists have a seemingly single-minded focus on their research, but there are considerable benefits to having one foot in the lab and the other in the clinic. Working with patients gives researchers a daily reminder of the people they are working so hard to help and allows them to investigate the effects of promising but still experimental treatments in willing volunteers. That’s one of the main reasons why the IRP’s Lasker Clinical Research Scholars Program is designed to accelerate the careers of promising early-career physician-scientists. 

This year, four NIH researchers began receiving support from the Lasker program, allowing them to dramatically expand their cutting-edge research. From investigating the roots of muscle-weakening genetic conditions to probing the mysteries of rare, hormone-producing tumors, these individuals will use the leg up provided by the Lasker Program to make new discoveries that could one day improve their patients’ lives. Read on to learn more about the exciting research the latest crop of Lasker Scholars is pursuing.

Dysfunction in Janitorial Gene Contributes to ALS

IRP Study Points to Treatment Target for Fatal Neurological Disorder

Just like we throw out our busted toasters and other appliances, our cells must continuously dispose of malfunctioning equipment to keep themselves working optimally. In certain neurological diseases, though, neurons die because they can’t get rid of misbehaving molecules. New IRP research provides crucial insights into a key player in this process, suggesting that restoring the function of a particular gene or boosting the levels of the enzyme it produces could help patients with the devastating disease known as amyotrophic lateral sclerosis (ALS).

IRP Graduate Students Show Off Their Work at Annual Symposium

Event Highlights Efforts of Early-Career Researchers

The IRP’s reputation as a leader in biomedical research attracts scientists in all stages of their careers and from all corners of the U.S. and the world. Once a year, the motley collection of graduate students who are completing their Ph.D. research in NIH labs gets to tout its scientific accomplishments at NIH’s Graduate Student Research Symposium, which took place this year on February 15.

During the event’s two poster sessions, more than 120 IRP graduate students presented the results of their research so far, from the development of better ways to grow retina-like collections of cells in the lab to insights into how the brain regulates feelings of hunger. Read on for a brief look at a few of the IRP’s brilliant budding scientists and the discoveries they showed off at the event.

Antibody Assault Shows Promise Against Dormant HIV

Treatment Strategy Could Mop Up Virus Hiding in Patients’ Bodies

As temperatures drop in the fall, a variety of species from groundhogs to bears prepare to wait out the winter in their dens. Much like these animals, HIV also goes into hibernation when conditions are tough, a trait that has long stymied efforts to develop a cure. However, IRP researchers recently tested a promising strategy that might one day be used to flush out and kill dormant remnants of HIV.

IRP’s Eugene Koonin Elected to National Academy of Medicine

Scientist Decoded DNA to Build a Genomic Tree of Life

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

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

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

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

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

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.
