WebHypoxia leads to activation of many cellular adaptive processes which are regulated by the transcription factor hypoxia-inducible factor-1 (HIF-1). HIF-1 consists of HIF-1α and HIF-1ß subunits and levels of HIF-1α protein are regulated by HIF prolyl-hydroxylase enzymes (PHD1, 2, 3). The aim of the c … 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]

WebHypoxie-induzierter Faktor (HIF) ist ein Transkriptionsfaktor und Hypoxie-induzierbarer Faktor, der die Versorgung der Zelle mit Sauerstoff reguliert, indem er eine Balance zwischen Sauerstoffbedarf und Sauerstoffversorgung herstellt. Seine Entdeckung wurde 2024 mit dem Nobelpreis für Physiologie oder Medizin prämiert.. HIF besteht aus einer … WebAt early reaction periods, H(2)O(2) induced HIF-1α but at prolonged observation phases the opposite occurred. Herein, modulation of PHD activity appeared to be the key element, because knockdown and inhibition of the PHD2 prevented reduction of HIF-1α. However, H(2)O(2) treatment constantly suppressed HIF-1 transactivation at all time-points.
