The Transcriptional-Metabolic Interactions under Hypoxia. A variety of genes upregulated transcriptionally under hypoxia affect cancer cell metabolism and behavior. The balance of glycolysis and oxidative phosphorylation along with the amounts of cholesterol, triacylglycerols, and other metabolites can metabolically “prime” a cancer cell to seed at specific organs during metastasis.
