HIF-1α
Hypoxia-Inducible Factor 1-Alpha
Also known as: HIF1A
Master transcription factor coordinating the cellular response to low oxygen.
Biological Function
HIF-1α is the oxygen-sensing transcription factor that activates gene programs enabling cells to survive under hypoxic conditions. Under low oxygen, HIF-1α escapes degradation, dimerizes with HIF-1β, and drives expression of VEGF, erythropoietin, glycolytic enzymes, and glucose transporters. It is a central regulator of the adaptive response to exercise, altitude, and tissue ischemia.
Why Biomeme Monitors This Target
HIF-1α is a convergence point for tissue repair (TB-500) and performance applications. Monitoring HIF-1α target gene expression reveals whether wound-healing or exercise adaptation programs are being activated at the molecular level. It also provides insight into tumor angiogenesis risk with chronic VEGF-upregulating therapies.
Expression Context
Stabilized by hypoxia, exercise, and tissue injury. Rapidly degraded under normal oxygen conditions (PHD/VHL pathway). Also activated by certain metabolites independent of oxygen levels.
