Mothers’ Smoking Leaves Unique Marks on Infants’ DNA

Smoking While Pregnant Affects a Woman’s Genes Differently From Her Baby’s

Decades of public health campaigns have made the health consequences of smoking common knowledge. However, for the few women who smoke while pregnant, the habit can affect not only their own bodies but also those of their unborn children. Intriguingly, according to a new study led by IRP researchers, so-called ‘epigenetic’ changes to DNA that can alter the behavior of genes differ significantly in smoking mothers compared to their babies, suggesting that maternal smoking may have unique, long-lasting effects on the way a child’s body functions.

The Social Side of Health

Understanding Social and Behavioral Research in the IRP

The NIH IRP is world-renowned for its high-risk, high-reward biomedical research. While the NIH may be best known for its clinical and biomedical research on topics from cancer to allergies to addiction, IRP investigators have also produced a rich body of work conducted in the area of social and behavioral research (SBR). In this post, I will describe how SBR furthers the NIH’s goals of improving human health with some examples of the excellent work done by SBR investigators in the IRP.

Overlooked Immune Cells Trigger Preterm Labor

New Insights Could Help Reduce Premature Births

Any baby born less than 37 weeks after conception is considered premature, but not all premature births have the same root cause. In a new study, IRP researchers have detailed how a particular component of the immune system can trigger premature labor, which could help doctors prevent more preterm births.

Supercomputing Pushes Pregnancy Research Forward

Virtually all parents would agree that having kids is a massive undertaking, and not just after they’re born. Many couples struggle to conceive, and each year thousands of American women experience complications when giving birth. With the help of the NIH’s state-of-the-art supercomputer, Biowulf, IRP senior investigator Rajeshwari Sundaram, Ph.D., develops and refines statistical tools that can guide prospective parents and their doctors through these challenges.

Postbac Poster Day Highlights Budding Researchers

On Wednesday, May 2, hundreds of researchers gathered at NIH’s Natcher Conference Center to show off their recent discoveries. But unlike a typical scientific conference, the letters “M.D.” and “Ph.D.” were noticeably absent from these scientists’ credentials. Instead, the event — NIH’s annual Postbac Poster Day — celebrated the accomplishments of individuals participating in the NIH Postbaccalaureate Intramural Research Training Award (IRTA) Program.

In Utero Exposure to Immune Molecules May Affect Neurocognitive Development

In the midst of the 1957 Asian flu pandemic, doctors and researchers were understandably focused on treating patients and developing ways to contain the outbreak. It wasn’t until 30 years later that scientists began reporting that women who were pregnant when they caught the virus were more likely to have children who would later be diagnosed with schizophrenia.1 While that relationship remains controversial,2 numerous studies have since linked activation of a pregnant woman’s immune system with an increased risk that her child will develop certain psychiatric disorders, including not just schizophrenia but also autism spectrum disorder and major depressive disorder.3 A new IRP study has now expanded on this work by showing that exposure to higher levels of two immune system molecules in utero can noticeably alter the neurological and cognitive development of young children.4

Morning Sickness Associated with Lower Miscarriage Risk

During the first trimester of pregnancy, many women experience what’s commonly known as “morning sickness.” As distressing as this nausea and vomiting can be, a team of NIH researchers has gathered some of the most convincing evidence to date that such symptoms may actually be a sign of something very positive: a lower risk of miscarriage.

It's Time for a Science FARE!

Speaking at the NIH Research Festival in September, Michael Gottesman, M.D., the NIH Deputy Director for Intramural Research said, “The real research is being done by the fellows, by the students.” The FARE awards are meant to commend those researchers doing outstanding work at the NIH.
