Histone acetylation states in cancer are impacted by metabolic reprogramming, which modifies the absolute amounts of acetyl-CoA and the ratio of acetyl-CoA to coenzyme A. Because of its role in acetyl-CoA gene rating through the ligation of acetate and CoA, ACSS2 can cause HIF-2 to become acetylated, which inhibits EMT under hypoxic conditions in HCC.415 Overexpression of ACSS2, which promotes acetylation of H3K27 in the ATG5 promoter region, is used to achieve reduced breast cancer cell proliferation, migration, and invasion. This evidence concerns the gene ACSS2 and breast cancer.
