Background: HIF-2 alpha/EPAS1
HIF-1 or hypoxia inducible factor 1, is a transcription factor commonly referred to as a "master regulator of the hypoxic response" for its central role in the regulation of cellular adaptations to hypoxia. Similarly, HIF-2 alpha plays a role in cellular responses to hypoxia, but whereas HIF-1 alpha is ubiquitously expressed, HIF-2 alpha is predominantly expressed in the vascular endothelium at embryonic stages and after birth in select cells and tissue types (e.g., fibroblasts, hepatocytes and myocytes at 96kDa) (4). Following a similar mechanism to HIF-1 alpha, HIF-2 alpha is stabilized under hypoxic conditions by the formation of a heterodimer with an ARNT/HIF-1 beta subunit. Stable HIF-2 alpha-ARNT/HIF-1 beta heterodimers engage p300/CBP in the nucleus for binding to hypoxic response elements (HREs), inducing transcription, and thus regulation of genes (e.g., EPO, VEGFA). HIF-1 predominantly transactivates genes involved in glycolytic control and pro- apoptotic genes (e.g., LDHA and BNIP3), and HIF-2 regulates the expression of genes involved in invasion and stemness (e.g., MMP2, and OCT4). Common gene targets for HIF-1 and HIF-2 include VEGFA and GLUT1 (5).
The HIF-2 alpha subunit is rapidly targeted and degraded by the ubiquitin proteasome system under normoxic conditions. This process is mediated by oxygen-sensing enzymes, prolyl hydroxylase domain enzymes (PHDs), which catalyze the hydroxylation of key proline residues (Pro-405 and Pro-531) within the oxygen-dependent degradation domain of HIF-2 alpha (5). Once hydroxylated, HIF-2 alpha binds the von Hippel-Lindau tumor suppressor protein (pVHL) for subsequent ubiquitination and proteasomal degradation (5,6).
