Resumo
We studied the mechanisms of adaptation of human breast cancer cells MCF-7 to hypoxia and analyzed the role of AMPK/mTOR signaling pathway in the maintenance of cell proliferation under hypoxic conditions. It was found that long-term culturing (30 days or more) of MCF-7 cells under hypoxic conditions induced their partial adaptation to hypoxia. Cell adaptation to hypoxia was associated with attenuation of hypoxia-dependent AMPK induction with simultaneous constitutive activation of mTOR and Akt. These findings suggest that these proteins can be promising targets for targeted therapy of tumors developing under hypoxic conditions.
