We think this one is groundbreaking: Do you wonder how #SGLT2 inhibitors protect from heart failure? We show that #empagliflozen directly activates PANK1, rate-limiting for CoA synthesis, in human hearts. You read it here first! biorxiv.org/content/10.1101/…

My first author paper from my thesis work has been uploaded to BioRxiv! We identified Mecr as important for T cell fitness in in vivo CRISPR screens. I have further worked with Mecr and am the first to show it regulates T cell function and metabolism.

New preprint from the lab is online! The product of a stellar collaboration with @Muir_Lab, we explore a chemically defined physiologic media formulation based of the metabolite of tumor interstitial fluid (TIF, or “tumor juice”) and its effects on T cell function! A brief 🧵1/

*New paper alert* I’m happy to share our latest study, out this week in @NatureComms. Led by former postdoc Nate Ward (who now leads his own lab at @MoffittNews), we asked how mitochondria cope with cystine starvation. nature.com/articles/s41467-0…

A second-generation degrader of the enzyme AKT—a key supporter of cancer cell proliferation and survival—can deplete AKT and halts breast cancer cell growth, especially in cells with basal JNK kinase activity. @alex_toker @BIDMChealth scim.ag/6a1
