Modern medical advances mean that many people are not “only flesh and blood.” Mechanical devices and substances created in medical labs are commonly replacing or being added to parts of people’s bodies. A new IRP study has shed light on how some of those materials might influence the body’s healing process, providing insights that could eventually spur the creation of new ones that influence the behavior of the body’s immune system and allow doctors to better direct how the body repairs itself.

Examining Genetic Influences on Lung Cancer

IRP Research Investigates Disease’s Roots Beyond Smoking

Today is World Lung Cancer Day, bringing increased awareness to a disease most commonly associated with smoking tobacco products. Yet even though cigarette smoking rates have decreased over the past few decades, this deadly disease remains responsible for more deaths than any other type of cancer — more than 125,000 per year in the U.S. alone. In fact, between 10 and 25 percent of lung cancers occur in people who never smoked.

IRP Stadtman Investigator Jiyeon Choi, Ph.D., has always been curious about how our DNA influences the traits we have and our risk for diseases. When it comes to genes’ contribution to cancer risk, the stakes are particularly high, but Dr. Choi noticed a gap in research when it came to understanding the role genetic variation plays in lung cancer risk. She and her research team aim to fill this gap using a battery of high-tech genomic studies to root out the genes and molecular processes that make some people more susceptible to the disease.

Symposium Celebrates Award-Winning Female Scientists

Three Young Women Honored at Annual Event

Dr. Brittany Lord

There’s no doubt that science flourishes when it welcomes individuals with different backgrounds and perspectives. In pursuit of that goal, NIH has put considerable effort into closing the gender gap in the biomedical sciences, a field in which men significantly outnumber women, especially as the heads of labs and in leadership positions. Those efforts have so far yielded promising progress, with the proportion of women in IRP senior investigator positions increasing from 22 percent at the end of fiscal year 2016 to 27 percent at the end of fiscal year 2022. Over that same time period, women went from comprising 38 percent of IRP tenure-track investigators to 44 percent.

Part of what makes the IRP a welcoming place for female scientists is the NIH Women Scientists Advisors (WSA), a group of IRP scientists elected to represent the interests of women in the IRP. Once per year, the WSA selects a few female postdoctoral fellows or graduate students conducting research at NIH as WSA Scholars. At a symposium on April 13 honoring the achievements of this year’s Scholars, the awardees presented their efforts to learn more about a devastating childhood neurological condition, decrease health disparities in breast cancer, and use stem cells to investigate the roots of a nerve-destroying disorder. Read on to learn more about this year’s WSA Scholars and the important work they’re doing in their IRP labs.

IRP’s Jennifer Webster-Cyriaque Elected to the National Academy of Medicine

NIH Scientist Proves What Happens in the Mouth Doesn’t Stay in the Mouth

Dr. Jennifer Webster-Cyriaque

For many people, good oral health means a pretty smile, not necessarily a healthy body. However, poor dental health can lead to serious illness and disability. IRP senior investigator Jennifer Webster-Cyriaque, D.D.S., Ph.D., has spent her career illuminating the connection between our mouths and our overall health. Dr. Webster-Cyriaque, who recently joined NIH as Deputy Director of the National Institute of Dental and Craniofacial Research (NIDCR) and Chief of the Viral Oral Infections in Immunosuppression and Cancer Laboratory at the National Institute of Allergy and Infectious Diseases (NIAID), was elected to the National Academy of Medicine in October for her seminal contributions to our understanding of viruses that infect the mouth.

A Look Back at the IRP’s History-Making Women

NIH Archives Document the Tremendous Importance of Female Scientists

Women’s History Month is celebrated every March, and women scientists have undoubtedly made invaluable contributions to IRP research over the course of NIH’s history. Despite this, women still remain under-represented in biomedical science at NIH and elsewhere today, prompting the IRP to make supporting the careers of female researchers an important priority. While NIH works to rectify the gender imbalance in scientific research, it’s important to take time to celebrate the many women who, even when confronted with significant historical obstacles, have made a name for themselves in the lab and on the pages of scientific journals. Join me in taking a look through the archives of the Office of NIH History & Stetten Museum to learn about some of the many women scientists who have been at the forefront of science and administration at NIH.

Postdoc Profile: Eavesdropping On Bacterial Banter

Dr. Tiffany Zarrella Examines Communication Between Bacteria to Combat Persistent Infections

Dr. Tiffany Zarella

Facebook’s nearly 3 billion users may seem like a huge social network, but it pales in comparison to the conversations among the trillions of microbes that live inside a single human body. Few people know this better than IRP postdoctoral fellow Tiffany Zarrella, Ph.D., who spends her days eavesdropping on the messages bacteria send to one another to improve treatment for stubborn infections.

Dr. Zarrella was drawn to the bacterial world in microbiology lab courses while earning a biochemistry degree at Syracuse University in New York. After graduation, she obtained a research technician position at Albany Medical College, where she worked on projects centered around infectious bacteria and how they respond to their environments. She continued this thread of research in graduate school, moving on to a new study to discover how Streptococcus pneumoniae bacteria, which often cause ear infections and pneumonia, use a particular signaling molecule to resist antibiotic treatments and evade vaccines.

Research Helps Guide Families Safely Through Pandemic

IRP’s Diana Bianchi Honored for Leading Pediatric COVID Response

Dr. Diana Bianchi

When the first reports of COVID-19 came out, infectious disease experts and healthcare providers thought children might be spared its most dire effects. After all, the news reports and health statistics showed that nearly all serious cases occurred in the elderly, people with certain pre-existing conditions, and those who spent their days and nights caring for COVID patients. However, as case counts rose and disruptions in daily life grew, the medical and psychological effects of COVID on children became apparent — and the impact was alarming. It soon became clear that something had to be done to understand the disease's effects on infants, children and teens, as well as pregnant women and traditionally underserved communities.

It was, appropriately, Mother’s Day when then-NIH Director Francis Collins sought help from Diana W. Bianchi, M.D., Director of the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) and a senior investigator in the National Human Genome Research Institute (NHGRI). An expert in infant health and genetic conditions like Down syndrome, Dr. Bianchi was just the person to initiate large-scale studies across the country to assess the severity of COVID in specific populations, the safety and efficacy of vaccination and treatment, and the impact of mitigation efforts such as masking. For this critical leadership, Dr. Bianchi was named a finalist for the 2022 Samuel J. Heyman Service to America Medal for COVID-19 Response.

Poster Days Spotlight Young Researchers

Budding Scientists Showcase Research at Annual Event

Yasmin Ali

Any scientist who wants to make game-changing discoveries has to start somewhere — even Albert Einstein worked in a patent office before landing his first job in academia. Through its Postbaccalaureate IRTA program, NIH hopes to give aspiring scientists more of a leg up than Einstein had by bringing them into IRP labs after they complete their undergraduate studies.

On April 26, 27, and 28, more than 900 recent college graduates participating in the program presented at this year’s virtual Postbac Poster Days. Read on to learn about a few of these young researchers and their contributions to the groundbreaking work being done at NIH.

Award Honors Promising Female Scientists

Women Scientists Advisors Select Three Young Researchers for Recognition

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.
