In addition, local hypoxic, acidic, and low-glucose environments further augment energy metabolism reprogramming in tumor cells, which not only upregulates antiapoptotic proteins, including protein kinase B (Akt) and hexokinase 2 (HK2) but also inhibits the proliferation of T lymphocytes, facilitating tumor cell immune escape [198]. This evidence concerns the gene AKT1 and neoplasm.
