Immune evasion is a hallmark of cancer, enabling tumor cells to escape from anti-tumor immunity. Hypoxia is a well-known feature of almost all solid cancers and a characteristic of cold immunity. It accounts for impaired immunity, alterations in tumor metabolism and cancer progression toward metastasis [1], [2].
WebJun 20, 2024 · Tumour hypoxia greatly influences breast cancer progression [1,2,3] and is generally linked to poor prognosis in breast cancer patients due to increased proliferation, cell survival, invasive/metastatic ability, therapy-resistance and altered cancer stem cell activity [4,5,6,7,8,9].The main mediator of signalling in these poorly oxygenated areas is … WebApr 5, 2016 · We report that exposure of breast cancer cells to hypoxia stimulated hypoxia-inducible factor (HIF)-1α- and HIF-2α–dependent expression of AlkB homolog 5 (ALKBH5), an m 6 A demethylase, which demethylated NANOG mRNA, which encodes a pluripotency factor, at an m 6 A residue in the 3′-UTR.
