433: Lactate, HSP90α and the Mitochondrial Switch
23:55
Wu G et al., Proceedings of the National Academy of Sciences - This episode examines a PNAS study that identifies site-specific lactylation of HSP90α as a metabolic signal linking glycolysis to mitochondrial biogenesis in ovarian cells. Lactylation at K58 and K616 modulates HSP90α phosphorylation, enabling nuclear import of PGC1α and LRPGC1, boosting mitochondrial number, cholesterol import,…
