Improving Medical Student Access to Nutrition During the Core Surgery Clerkship.

The rigorous demands of medical education create circumstances that can make it challenging to maintain a healthy diet. Evaluations from students at an urban medical school in the northeast U.S.

Oncometabolites suppress DNA repair by disrupting local chromatin signalling.

Deregulation of metabolism and disruption of genome integrity are hallmarks of cancer. Increased levels of the metabolites 2-hydroxyglutarate, succinate and fumarate occur in human malignancies owing to somatic mutations in the isocitrate dehydrogenase-1 or -2 (IDH1 or IDH2) genes, or germline mutations in the fumarate hydratase (FH) and succinate dehydrogenase genes (SDHA, SDHB, SDHC and SDHD), respectively. Recent work has made an unexpected connection between these metabolites and DNA repair by showing that they suppress the pathway of homology-dependent repair (HDR) and confer an exquisite sensitivity to inhibitors of poly (ADP-ribose) polymerase (PARP) that are being tested in clinical trials.
