Understanding the Long-term Effects of Adverse Childhood Experiences

A young girl wears a backpack while sitting on a park bench, with her knees tucked under her chin.

Adverse childhood experiences, such as poverty, family instability, and parental separation, can have an enduring impact on a person’s health and development. Identifying these effects can help inform policies and programs to help children who have experienced adverse events.

Read about work from the Social and Behavioral Sciences Branch on links between adverse childhood experiences and the risk for premature death in adulthood.

Understanding the Link Between Fibroids and Birth Weight

A pregnant woman with her hands on her abdomen stands in front of a large window.

Uterine fibroids, the most common non-cancerous tumors in women of childbearing age, occur in roughly 11% of pregnancies. Some studies have linked fibroids in pregnancy to lower infant birthweight and a higher risk of preterm birth.

Read about work from the Epidemiology Branch that furthers understanding of the relationship between fibroids and fetal growth.

Understanding Gene Expression During Early Development

The image is titled, “The Anterior Foregut,” and has the following parts labeled, from top to bottom: esophagus, trachea, lungs, and stomach. The lungs are stained bright green and the other organs are purple. The image is against a black background.

Genes are often visualized as long strings that are highly organized within the cell’s nucleus, with mechanisms that help fold, compact, and unfold areas as needed to direct cellular growth, function, and development.

Read about work from the Rocha Lab on a gene regulatory mechanism that involves CTCF protein loops.

Understanding the Role of Cholesterol in Membrane Reshaping

The lipids (salty fats) in cell membranes play a key role in enabling large substances to enter and exit the cell by promoting the formation of fusion and fission pores—structures that connect two membranes. The physics of such lipid interactions directly influences processes related to disease, such as the ability of viruses to penetrate and bud from cells.

Read about work from the Sodt Lab that furthers understanding of the role of the lipid cholesterol in membrane reshaping.

Optimizing Fertility Preservation for Girls with Childhood Cancer

A health care provider smiles at a young patient while holding her hands. The girl is wearing a headscarf.

Treatments for childhood cancer often involve chemotherapy and radiation therapy, which can damage reproductive tissues. For girls, a procedure called ovarian tissue cryopreservation can help preserve future fertility.

Read about work from the Gomez-Lobo Lab on ovarian tissue cryopreservation in girls who undergo bone marrow transplants to treat their cancer.

Deciphering How Flu Viruses Enter Cells

Influenza viruses infect cells in a multi-step process, during which the virus opens a hole in the membrane to inject its genetic material into the cell. Understanding this process may inform development of new technologies to insert medications, genes, and proteins into cells.

Read about work from the Zimmerberg Lab that furthers understanding of the molecular interactions underlying viral entry into cells.

Identifying Genetic Causes of Rare Vascular Conditions

Blood vessels are responsible for transporting oxygen throughout the body. Malformations in blood vessels can lead to growth differences and other health problems.

Read about work from the Sheppard Lab on a rare malformation in capillaries—the smallest type of blood vessel—that causes an undergrowth condition.

Discovering Biomarkers for a Rare Disease

Niemann-Pick disease type C1 (NPC1) is a rare neurodegenerative disorder for which there are no FDA-approved therapies. Identifying biomarkers that indicate NPC1 severity and progression could facilitate clinical care and aid development of treatments.

Read about work from the Porter Research Group to identify biomarkers that can be measured in the cerebrospinal fluid of people with NPC1.

Understanding How Neural Circuits Process Sensory Information

A donut-shaped mass of red cells is dotted with green against a black background. The green fibers are bunched along the lower left edge.

The brain is an extraordinary and complex organ responsible for gathering, organizing, and processing sensory information from the environment. To understand the intricacies of brain function, many scientists employ simple model systems, like the sense of smell in insects, as valuable tools for investigation.

Read about work from the Stopfer Lab on how olfactory neurons respond to smells with several different patterns of activity.

Identifying a Novel Function for a Metabolic Regulator

The protein complex TORC1 controls cell growth in organisms from yeast to humans. Improving understanding of how TORC1 is regulated by the protein complex GATOR may aid development of drugs to treat diseases such as epilepsy and cancer.

Read about work from the Lilly Lab that identified a novel function for the protein Wdr59 in regulating the GATOR2 subcomplex.
