Hif glut1
WebHypoxia-inducible factor (HIF) is a sensor of hypoxia and a regulator of the cellular hypoxic response. HIF is a heterodimeric complex comprised of an α-subunit, usually HIF-1α, and a β-subunit, usually the aryl hydrocarbon receptor nuclear translocator (ARNT). Under normoxic conditions HIF-1α is polyubiquitylated and targeted for ... WebO HIF-1a aumenta a atividade e a expressão de GLUT1 e GLUT3, resultando em aumento da captação de glicose, elevação das atividades enzimáticas da hexoquinase 2 (HK2) e fosfofrutoquinase B3 (PFKFB3) e aumento da produção de …
