Research advances in butyrogenic microbes and butyrate in the treatment of hepatocellular carcinoma

摘要: 肝细胞癌(HCC)是一种高病死率的肝脏恶性肿瘤,其发生发展与肠道菌群及代谢产物密切相关。丁酸盐是由肠道微生物代谢产生的一种短链脂肪酸,在保护肠道屏障、调节免疫应答以及抗肿瘤效应等方面均发挥重要作用。HCC患者普遍伴有肠道产丁酸菌丰度降低和丁酸盐代谢失调现象,这为基于微生物及代谢产物的HCC治疗提供了思路。现有研究初步表明,产丁酸菌及丁酸盐对HCC治疗兼具疗效预测与协同增效作用,其临床应用前景广阔。本文系统阐述两者在HCC进展中的特征,归纳其联合系统治疗策略的相关研究进展,同时为今后研究方向提供新见解,以推进其临床实践。Abstract: Hepatocellular carcinoma (HCC) is a hepatic malignancy with a high mortality rate, and the development and progression of HCC is closely associated with gut microbiota and their metabolites. Butyrate is a kind of short-chain fatty acid produced by gut microbiota through metabolism, and it plays an important role in various aspects such as protecting intestinal barrier, regulating immune response, and exerting an antitumor effect. Notably, there is a reduction in the abundance of butyrogenic microbes and dysregulation of butyrate metabolism in patients with HCC, which provides new ideas for the treatment of HCC based on microbes and their metabolites. Current studies have preliminarily shown that butyrogenic microbes and butyrate exhibit both predictive and synergistic effects in the treatment of HCC and thus have broad prospects for clinical application. This article systematically elaborates on their characteristics in the progression of HCC, summarizes related research advances in their combination with systemic treatment strategies, and provides new insights for future research directions, in order to promote their clinical application.
