WebHypoxia-inducible factor. Hypoxia-inducible factors ( HIFs) are transcription factors that respond to decreases in available oxygen in the cellular environment, or hypoxia. [1] [2] They are only present in parahoxozoan animals. [3] Web17 de out. de 2012 · In this study, we addressed the reverse possibility of a metabolic control of HIF-1 in tumor cells. We report that lactate, the end-product of glycolysis, inhibits prolylhydroxylase 2 activity and activates HIF-1 in normoxic oxidative tumor cells but not in Warburg-phenotype tumor cells which also expressed lower basal levels of HIF-1α.
