Cervical cancer is still an important problem perplexing health management in developing countries. Previous studies have shown that cervical cancer cells show markers of aerobic glycolysis, suggesting that these tumors may secrete lactic acid. Through the biological characterization of lactate gene in tumor and its relationship with immune cells in tumor microenvironment, a lactate scoring system capable of evaluating cancer prognosis was constructed to explore the molecular mechanism of lactate metabolism disorder affecting prognosis. 29 hub genes in this study were differentially expressed in cervical cancer, including 24 genes related to lactate metabolism, LDHA in Lactate dehydrogenase (LDH) group, SLC16A3 in Monocarboxylate transporters (MCT) group and three Histone lactation modification related genes (EP300, ACAT1, ACACA). More importantly, we found that from an epigenetic point of view, histone lactation plays an important role in the pathogenesis and prognosis of cervical cancer. Mainly affect the prognosis of the disease through changes in the infiltration of plasmacytoid Dendritic Cell (pDC) and Central Memory T cell (Tcm) in the tumor immune microenvironment. Lactate inhibition may be a useful tool for anticancer therapy.
宫颈癌仍是困扰发展中国家卫生管理的一个重要问题。以往研究表明,宫颈癌细胞表现出有氧糖酵解的标志物,提示这些肿瘤可能分泌乳酸。通过对肿瘤中乳酸基因的生物学特性及其与肿瘤微环境中免疫细胞的关系进行研究,构建了一种能够评估癌症预后的乳酸评分系统,以探讨乳酸代谢紊乱影响预后的分子机制。本研究中的29个枢纽基因在宫颈癌中差异表达,包括24个与乳酸代谢相关的基因、乳酸脱氢酶(LDH)组中的LDHA、单羧酸转运蛋白(MCT)组中的SLC16A3以及3个与组蛋白乳酸修饰相关的基因(EP300、ACAT1、ACACA)。更重要的是,我们从表观遗传学角度发现,组蛋白乳酸化在宫颈癌的发病机制和预后中起重要作用。主要通过改变肿瘤免疫微环境中浆细胞样树突状细胞(pDC)和中枢记忆T细胞(Tcm)的浸润来影响疾病的预后。乳酸抑制可能是一种有用的抗癌治疗工具。
