Özet

Objective: AMP-activated-protein-kinase (AMPK) regulates cellular energy-homeostasis. Eukaryotic-elongationfactor-2-kinase (eEF2K) plays important roles in regulating protein-synthesis, functions similarly to AMPK to protect cancer-cells from metabolic stress. Tumor-hypoxia induces angiogenesis with activation of hypoxia-inducible-factor-1-alpha (HIF-1 alpha). AMPK might be implicated both in regulation of protein-translation and response-to-hypoxia. We aimed to investigate the effects of AMPK modulation on regulation of protein translation and response-to-hypoxia by evaluating eEF2K and HIF-1 alpha proteins in breast and hepatocellular cancers.
