UT Southwestern researchers have discovered a mechanism that cells use to degrade microRNAs (miRNAs), genetic molecules that regulate the amounts of proteins in cells.

For decades, physicians have known that many kinds of cancer cells often spread first to lymph nodes before traveling to distant organs through the bloodstream.

Two new studies led by UT Southwestern scientists outline how individual cells maintain their internal clocks, driven both through heritable and random means.

When he was just 6 months old, Todd Roberts moved with his family from Houston to Brazil to support his scientist father’s research on malaria and other mosquito-borne diseases. There, he simultaneously learned Brazilian Portuguese and English, becoming the most fluent bilingual speaker in his household.

Neurons in a part of the brain known as the ventromedial hypothalamus (VMH) appear to direct the body to boost endurance in response to exercise, a study co-led by researchers at UT Southwestern Medical Center shows.

UT Southwestern researchers have uncovered how cells in general modulate their energy consumption based on their surroundings.

Immunotherapy drugs that target a protein called programmed death ligand 1 (PD-L1) on the surface of cancer cells have quickly become a mainstay to treat many forms of cancer, often with dramatic results.

When activated in ovarian cancer cells, the receptor for the body’s primary stress hormone alters the tumor environment in ways that blunt immune response, according to new research led by UT Southwestern Medical Center.

Scientists at Children’s Medical Center Research Institute at UT Southwestern (CRI) have discovered that large pieces of DNA can transfer directly between human cells, and the DNA can persist and change how the recipient cell functions.
