Core Tip

Core tip: Previous research has shown that deacetyltransferase inhibitors not only induce cell cycle arrest, differentiation and apoptosis of many tumor cells in vitro, but also inhibit tumor growth in tumor-bearing animals. They are through the acetylation modification of deacetyltransferase inhibitor on histone. Only a few studies have focused on the acetylation modification by deacetyltransferase on non-histone. This is the first study to identify acetylated proteins in gastric cancer cells before and after exposure to trichostatin A to explore the effect of lysine acetylation of related proteins on the regulation of gastric cancer cell proliferation. Moreover, the lysine-acetylated proteins and the modified sites in AGS cells were assessed. We explored whether ATP5O was obviously acetylated after trichostatin A treatment in AGS cells.
