Web1 de fev. de 2010 · HIF-1 target genes involved in glucose and energy metabolism. HIF-1 activates the transcription of SLC2A1 and SLC2A3, which encode the glucose transporters GLUT1 and GLUT3, respectively, as well as HK1 and HK2, which encode hexokinase, the first enzyme of the Embden–Meyerhoff (glycolytic) pathway [9]. WebHIF-1 is a heterodimeric transcription factor complex, composed of two subunits: an O 2-responsive HIF-1α subunit, and a constitutively expressed HIF-1β subunit. The intact HIF-1 complex binds to hypoxia response elements (HREs) in the promoters of genes that govern diverse processes, such metabolism, proliferation, apoptosis, and angiogenesis.
