Last week we celebrated two Tashjian Award recipients for Junior Faculty: Dr. Jessalyn Ubellacker and Dr. Young Yon. Their innovative work on cancer metabolism, ferroptosis, and cancer cachexia advances how we understand and treat disease. Honored to recognize their achievements and future impact.

Honored to share that Dr. Gökhan Hotamışlıgil has been elected to the National Academy of Sciences, one of the highest distinctions in science recognizing outstanding, sustained contributions to research. Huge congratulations to Dr. Hotamışlıgil on this remarkable and well-deserved honor!

Clear evidence from Josh Shin in our lab that mTORC1 signaling and autophagy reciprocally influence the length of primary cilia. Question remains how do changes in length affect cilia signaling and function in the largely quiescent cells comprising our brains and bodies. www.cell.com/iscience/ful...

New Molecular Metabolism study from the Biddinger Lab finds diabetes gene TCF7L2 is crucial for hepatic zonation and glutamine metabolism. Liver-specific Tcf7l2 knockout mice exhibit metabolic reprogramming, and decreased glutamine in humans with the rs7903146 variant. #BiddingerLab hsph.me/Tcf7l2

The diabetes gene Tcf7l2 organizes gene expression in the liver and regulates amino acid metabolism

Though Tcf7l2 harbors the strongest genetic association with diabetes identified thus far, how it promotes metabolic disease remains unclear. Our aim …
