Tumor Hypoxic Microenvironment (THME)

The tumor hypoxic microenvironment refers to regions within solid tumors where oxygen levels are significantly lower than in normal tissues. This hypoxia arises due to rapid tumor cell proliferation, abnormal blood vessel formation, and high metabolic demand. Hypoxia promotes cellular adaptation through HIF-1α activation, metabolic reprogramming towards glycolysis (Warburg effect), immune suppression, and therapeutic resistance, ultimately contributing to increased aggressiveness, metastasis, and poor patient prognosis. Targeting the hypoxic microenvironment is a promising strategy for improving cancer treatment outcomes.
