The hypoxia inducible factor 1α (HIF-1α) is overexpressed in solid tumors driving tumor angiogenesis and survival. or Ago2 knockdown abrogates TX’s ability to suppress HIF-1α translation. Interestingly microtubule repolymerization after nocodazole washout allows HIF-1α mRNA to reenter active translation suggesting that microtubule dynamics exert tight yet reversible control over HIF-1α translation. Collectively we provide evidence… Continue reading The hypoxia inducible factor 1α (HIF-1α) is overexpressed in solid tumors
