Histone modifications regulate the structural status of chromatin and thereby influence the transcriptional status of genes. These processes are controlled by the recruitment of different enzymes to a specific genomic site. Furthermore, obtaining an understanding of these mechanisms could help delineate alternative treatment and preventive strategies for cancer. For example, in gastric cancer, cholecalciferol, curcumin, resveratrol, quercetin, garcinol and sodium butyrate are natural regulators of acetylation and deacetylation enzyme activity that exert chemopreventive and anticancer effects. Here, we review the recent findings on histone acetylation in gastric cancer and discuss the effects of nutrients and bioactive compounds on histone acetylation and their potential role in the prevention and treatment of this type of cancer.
组蛋白修饰调节染色质的结构状态,从而影响基因的转录状态。这些过程受不同酶在特定基因组位点募集的控制。此外,了解这些机制有助于确定用于癌症治疗和预防的替代策略。例如,在胃癌中,胆钙化醇、姜黄素、白藜芦醇、槲皮素、garcinol 和丁酸钠是乙酰化和去乙酰化酶活性的天然调节剂,具有化学预防和抗癌作用。在这里,我们综述了胃癌中组蛋白乙酰化的最新发现,并讨论了营养素和生物活性化合物对组蛋白乙酰化的影响及其在预防和治疗这种类型的癌症中的潜在作用。
