Hif atf4
WebHypoxia/anoxia promotes tumor aggressiveness and negatively impacts tumor response to therapy. Coordinate regulation of HIF-dependent and HIF-independent pathways has been shown to contribute to cellular adaptation to hypoxic stress, and to couple macromolecular synthesis rates to reduced energy availability. An important component of this type of … WebThe molecular mechanisms mediating nociception are unclear. Here, the authors show that the Activating Transcription Factor 4 (ATF4) is important for the response to heat …
