Abstract Hypoxia, a defining hallmark of solid tumors, arises from structurally and functionally abnormal vasculature, rapid cellular proliferation, and impaired perfusion, resulting in chronic and cycling oxygen deprivation within the tumor massThe hypoxic tumor microenvironment orchestrates extensive molecular reprogramming primarily through stabilization and activation of hypoxia-inducible factors (HIF-1 and HIF-2), which regulate broad transcriptional networks governing metabolism, angiogenesis, stemness, invasion, and immune modulation
