UNLABELLED: Hypoxia signaling induced by VHL deficiency fuels growth but also imposes metabolic stress on clear cell renal cell carcinomas (ccRCC). Many ccRCC cells depend on glutamine as the primary source of tricarboxylic acid (TCA) anaplerosis. Hypoxia-inducible factor α (HIFα) governs glycolysis but does not directly regulate glutamine metabolism; instead, the factor responsible for orchestrating glutamine metabolism and mitochondrial adaptations to hypoxia remains elusive. In this study, we...
