Background: HIF-1 alpha/HIF1A
HIF-1 or hypoxia inducible factor 1 (predicted molecular weight 93kDa), 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. In its active form under hypoxic conditions, HIF-1 is stabilized by the formation of a heterodimer of HIF-1 alpha and ARNT/HIF-1 beta subunits. Nuclear HIF-1 engages p300/CBP for binding to hypoxic response elements (HREs). This process induces transcription and regulation of genes including EPO, VEGF, iNOS2, ANGPT1 and OCT4 (4,5).
Under normoxic conditions, the HIF-1 alpha subunit is rapidly targeted and degraded by the ubiquitin proteasome system. This process is mediated by prolyl hydroxylase domain enzymes (PHDs), which catalyze the hydroxylation of key proline residues (Pro-402 and Pro-564) within the oxygen-dependent degradation domain of HIF-1 alpha. Once hydroxylated, HIF-1 alpha binds the von Hippel-Lindau tumor suppressor protein (pVHL) for subsequent ubiquitination and proteasomal degradation (4). pVHL dependent regulation of HIF-1 alpha plays a role in normal physiology and disease states. Regulation of HIF-1 alpha by pVHL is critical for the suppressive function of FoxP3+ regulatory Tcells (6). Repression of pVHL expression in chronic lymphocytic leukemia (CLL) B cells leads to HIF-1 alpha stabilization and increased VEGF secretion (7).
