HIF-1 plays a central role in reprogramming cancer metabolism by activating genes that enhance glucose uptake and glycolysis, such as glucose transporters and hexokinase. This shift from oxidative to glycolytic metabolism helps maintain redox balance and cell survival under hypoxia. HIF-1 is activated by various metabolic abnormalities in cancer cells, leading to a feed-forward loop that promotes tumor progression. HIF-1 regulates genes involved in glucose and energy metabolism, including SLC2A1, SLC2A3, HK1, HK2, LDHA, MCT4, and PDK1. These genes facilitate lactate production, mitochondrial autophagy, and pyruvate shunting away from the mitochondria. HIF-1 also activates BNIP3, which induces mitochondrial autophagy to maintain cell viability under prolonged hypoxia. HIF-1 is a transcription factor composed of HIF-1α and HIF-1β, with HIF-1α stability regulated by oxygen levels and hydroxylation. Under hypoxia, HIF-1α is stabilized, leading to increased gene expression. HIF-1 is involved in various metabolic pathways, including mitochondrial metabolism, NAD+ levels, and nitric oxide production. Genetic and metabolic activators of HIF-1 include mTOR activation, mitochondrial dysfunction, and alterations in NAD+ levels. HIF-1 also interacts with other factors like MYC to enhance tumor progression. The regulation of HIF-1 is crucial for cancer metabolism and has implications for cancer therapy.HIF-1 plays a central role in reprogramming cancer metabolism by activating genes that enhance glucose uptake and glycolysis, such as glucose transporters and hexokinase.
