IRP Breast Cancer Researchers Answer “Redditor” Questions

Reddit “Ask Me Anything” Commemorates Breast Cancer Awareness Month

Friday, October 11, 2019

Breast cancer touches the lives of millions of Americans every year. In 2019 alone, researchers expect more than 300,000 American women to be diagnosed with breast cancer, along with more than 2,600 men. Roughly one out of every eight American women will develop invasive breast cancer at some point in her lifetime, making it the second most commonly diagnosed cancer in American women.

On October 9, in recognition of National Breast Cancer Awareness Month, the NIH Intramural Research Program (IRP) partnered with the National Cancer Institute (NCI) to host a Reddit “Ask Me Anything” (AMA) with two prominent researchers in the NCI's Women's Malignancies Branch: Stanley Lipkowitz, M.D., Ph.D., and Alexandra Zimmer, M.D. Between Dr. Lipkowitz’s extensive knowledge of the cellular and molecular pathways involved in breast cancer and Dr. Zimmer’s expertise in the development of clinical trials for breast cancer treatments, the pair were able to offer intriguing insights on topics ranging from recent advances in breast cancer treatment to genetic and environmental factors that influence risk for the disease. Read on for some of the most interesting exchanges that took place, or check out the full AMA on Reddit.

Genes Contribute to Population-Based Differences in Antidepressant Response

5 Questions with Dr. Francis McMahon

Thursday, October 10, 2019

Depression is one of the most common mental health conditions in the U.S., affecting nearly seven percent of American adults each year. With the increasing social and economic pressures of the modern world likely contributing to depressive symptoms, it is more important now than ever to study depression and the factors that contribute to recovery.

A number of variables contribute to an individual’s overall mental health and response to treatment, including elements of nature and nurture that have long been studied at the NIH. In a 2013 study, researchers led by IRP senior investigator Francis McMahon, M.D., set out to understand the complex genetic factors that he believed might help explain why antidepressants are less effective for African Americans with depression than for other populations. His research revealed that differences in socioeconomics and health explained most of those differences in antidepressant response, and the remaining differences were explained by differences in genetic ancestry, rather than self-reported race. The discovery that genetics play a role in this health disparity could help close the gap and improve depression treatment for African Americans.

IRP’s Michael Gottesman Elected to National Academy of Sciences

NIH Investigator Recognized for Insights into Drug Resistance in Cancer

Tuesday, October 8, 2019

Dr. Michael Gottesman

The National Academy of Sciences, a private society established in 1863, is made up of the United States’ most distinguished scientific scholars, including nearly 500 members who have won Nobel Prizes. Members of the NAS are elected by their peers and charged with the responsibility of providing independent, objective advice on national matters related to science and technology in an effort to further scientific innovation in the U.S.

IRP Senior Investigator Michael Gottesman, M.D., is one of four IRP researchers who were elected to the Academy over the past two years. At the NIH, Dr. Gottesman plays two very different but equally important roles, serving as Deputy Director for Intramural Research while also leading the Laboratory of Cell Biology at the National Cancer Institute (NCI).

Chemical Tag-Team Shows Promise as Diabetes Treatment

Therapeutic Strategy Enhances Natural Blood Sugar Control

Tuesday, October 1, 2019

Just like Sonny needed Cher to achieve music super-stardom and Stephen Curry needed Kevin Durant to win back-to-back NBA championships, sometimes a cell or molecule in the human body needs a partner’s assistance to work optimally. IRP researchers recently showed that a synergy between a lab-designed drug and a molecule naturally produced in the body could make for a promising therapy for type 2 diabetes.

NIH Research Festival Hosts Postdoc Poster-Palooza

Annual Event Highlights Contributions of IRP Postdoctoral Fellows

Monday, September 16, 2019

Dr. Subhash Verma

At lunchtime last Wednesday, the NIH Clinical Center’s FAES Terrace echoed with the joyful sounds of scientists nourishing their bodies and their brains. While those stopping by the annual NIH Research Festival poster session could be forgiven for making a beeline straight for the food — including the submissions to this year’s Scientific Directors’ baking competition — once their plates were full, they took advantage of the opportunity to satiate their scientific curiosity as well by checking out the dozens of posters on display.

Yoga Helps Pain and Brain

Five Questions with Dr. Catherine Bushnell

Monday, September 9, 2019

Yoga is all the rage these days, with millions of people taking part in the practice for relaxation, meditation, and increasing flexibility and muscle strength. However, the benefits of yoga go beyond what most might think. In fact, the mind-body practice of yoga could have a significant impact on the lives of those living with chronic pain, a condition that affects tens of millions of Americans.

In the past, doctors often prescribed opioids to treat chronic pain. However, research has shown that people with chronic pain have anatomical and neurochemical alterations in the brain that make them less responsive to opioids. In addition, both the medical and political systems are currently contending with a public health crisis stemming from the over-use of opioid pain medications. As a result, researchers have been working to identify ways to better manage chronic pain, particularly without the use of medication.

Genome Modifications Affect Protein Variation in Tumors

Examining DNA Methylation Could Facilitate Targeted Cancer Therapy

Tuesday, September 3, 2019

As an amateur home chef, I know from experience that the ingredients you use can dramatically alter the way a recipe turns out. Leave out oregano and your tomato sauce will be bland; add too much red pepper and your plate of pasta will scorch your tongue.

In this way, it turns out, cooking is a lot like the process by which your genes manufacture the proteins that keep your body running. Just like the same recipe can result in a delicious or disappointing meal depending on how you modify it, a certain gene can produce several varieties of a single protein that behave in different ways. In some cases, these alterations may lead to disease. New IRP research has revealed that a genetic regulatory process called DNA methylation can contribute to cancer by changing which forms of a protein a gene produces.1

Tracing the Path From Inflamed Skin to Heart Disease

Five Questions with Dr. Nehal Mehta

Thursday, August 29, 2019

Most Americans know someone who has been affected by heart disease. Despite its status as the leading cause of death in the U.S. today, rates of heart disease have actually been steadily falling since they hit their peak in 1968. In fact, between 1970 and 2005, the life expectancy of the average American increased over 70 percent due in part to reductions in heart disease-related deaths.

Research conducted by IRP scientists has played a key role in curbing the heart disease epidemic by helping identify now well-known risk factors for heart disease, such as high blood pressure, obesity, and physical inactivity. However, not all risk factors are so commonly known. A 2017 study by IRP Lasker Clinical Research Scholar Nehal Mehta, M.D., M.S.C.E., revealed that untreated psoriasis — a chronic, relapsing, inflammatory skin disease — is linked to an elevated risk for premature coronary artery disease. Dr. Mehta’s research demonstrated a strong link between psoriasis-induced skin inflammation and and inflammation of the blood vessels, a precursor to heart disease. Through this study, the largest ongoing study of individuals with psoriasis to-date, Dr. Mehta’s team has concluded that controlling psoriasis-associated skin disease could be an important means of reducing cardiac risk in this population.

IRP’s Elaine Ostrander Elected to National Academy of Sciences

Genetic Research in Dogs Sheds Light on Human Disease

Monday, August 26, 2019

Dr. Elaine Ostrander

The National Academy of Sciences, a private society established in 1863, is made up of the United States’ most distinguished scientific scholars, including nearly 500 members who have won Nobel Prizes. Members of the NAS are elected by their peers and charged with the responsibility of providing independent, objective advice on national matters related to science and technology in an effort to further scientific innovation in the U.S.

IRP Senior Investigator Elaine Ostrander, Ph.D., is one of four IRP researchers who were elected to the Academy over the past two years. As head of the Cancer Genetics and Comparative Genomics Branch at the NIH’s National Genome Research Institute (NHGRI), Dr. Ostrander focuses on expanding our understanding of the genetic basis of human disease. However, her team does not just study humans. In fact, Dr. Ostrander works with dog owners, breeders, and veterinarians to study our canine companions and understand which genes control the variations seen across dog breeds. She specifically focuses on genes that control growth and genes associated with cancer susceptibility in an effort to understand why changes in those particular genes can cause illness in humans.

A New Approach to Fighting the Flu

Six Questions With Dr. Matthew Memoli

Thursday, August 22, 2019

We all know flu season as the time of year where people are loading up on hand sanitizer and heading to the doctor for their flu shot. However, many underestimate the severity of the flu. During a typical flu season, five to twenty percent of Americans fall ill, leading to more than 200,000 hospitalizations and 36,000 deaths. Because of this serious threat to the public, the IRP has a long track record of researching vaccines, antivirals, diagnostics, and other resources in an effort to prevent individuals from catching the flu and improve care for those who do.
