Weboverall protein synthesis. 25 This response is HIF-independent as both HIF-1α+/+ and HIF-1 α-/ MEFs respond similarly by phosphorylating eIF2α under hypoxic conditions. Since the oxygen availability within tumors fluctuates, multiple oxygen concentrations were used in vitro to assess the phosphorylation status of eIF2α. Indeed, at mild and Web1 de mar. de 2004 · Hypoxia is a key factor in tumor development, contributing to angiogenesis and radiotherapy resistance.
