Vanderbilt biochemists have discovered that the protein RADX has different biological effects at sites of DNA synthesis, depending on the cellular conditions — even though it works the same way in both stressed and unstressed cells. Read More

In recognition of Colorectal Cancer Awareness Month, the School of Medicine Basic Sciences will host a panel discussion, "On the Cutting Edge: Research Toward a Cure for Colorectal Cancer,” on Tuesday, March 30, from 11 a.m. to noon CT. Read More

Moderna, remdesivir, AstraZeneca. VUMC’s experts have played an integral role in the development of these marquee COVID-19 therapeutics behind the scenes.  Read More

David Cortez, Richard N. Armstrong Chair for Innovation in Biochemistry and professor of biochemistry, has been named interim chair in the Department of Biochemistry beginning Jan. 1. This follows the departure of John York, who was recently named chief science officer of California-based food technology startup Impossible Foods.

After discovering a new mechanism for DNA damage repair last year, Vanderbilt biochemists now provide direct evidence for how it works. Read More

Vanderbilt scientists have identified 593 proteins that are enriched at sites of DNA duplication and chromatin packaging of newly synthesized DNA. Read More

Investigators have discovered how a DNA repair pathway protein shields sites of damage to avoid mutations and maintain genome integrity. Read More

David Cortez and colleagues have discovered a new DNA repair mechanism. Read More

David Cortez and colleagues have found that a protein called RADX helps modulate a protein called RAD51 in order to make sure exactly the correct amount of DNA repair occurs. Read More

Postdoctoral scholar Natalie Hinkel has been named Postdoc of the Year by the Office of Postdoctoral Affairs for her exceptional scholarship. Assistant Professor of Psychology Anita Disney was honored as Mentor of the Year at the 12th annual Vanderbilt Postdoctoral Association Symposium April 12. Read More

Fifteen Vanderbilt faculty members conducting a range of biomedical and clinical research have been elected fellows of the American Association for the Advancement of Science. Six of the 15 have received funding through the university’s Trans-Institutional Programs initiative, which facilitates research and teaching collaborations across disciplines and are a core pillar of the university’s Academic Strategic Plan.

Researchers at Vanderbilt University Medical Center (VUMC) have discovered a protein that may lead to a new way to prevent resistance and improve outcomes for patients whose cancers have mutations in the tumor suppressor gene BRCA2. Read More

Kamakoti “Kami” Bhat, a fifth-year graduate student in the lab of David Cortez, Ph.D., professor of Biochemistry in the School of Medicine, has achieved a “first” for Vanderbilt University. Read More

Vanderbilt researchers have determined that a previously uncharacterized protein responds to DNA replication stress and has an essential role in maintaining the integrity of the genome. Read More

A top Vanderbilt-Ingram Cancer Center (VICC) investigator recently met with Vice President Joe Biden regarding the National Cancer Moonshot Initiative, a major national program to identify, fund and accelerate the most promising research leading to cancer cures. Read More

Vanderbilt investigators have discovered details about the mechanism of an important DNA repair protein that maintains genome stability. Read More

Telomeres – the caps on the end of chromosomes – are a source of stress for a particular protein involved in copying DNA, a new study reports. Read More

Vanderbilt investigators have generated a “parts list” for the molecular machinery that duplicates DNA each time a cell divides. The research has implications for cancer therapies that target components of this machinery. Read More
