【摘要】肝细胞癌(HCC)患者长期生存率不佳,药物疗效是影响其预后的重要因素。N6-甲基腺嘌呤(m6A)修饰是真核生物RNA中最丰富的修饰,可通过调节与癌症相关的生物学功能来影响癌症的发生发展及药物疗效。然而,m6A修饰在HCC药物治疗中的作用尚未完全阐明,因此,文章通过m6A修饰过程的3种调节成员(甲基转移酶、去甲基转移酶和结合蛋白)来论述其在HCC药物治疗中发挥的生物学作用,进而提出m6A修饰调节成员可作为HCC预后评估的生物标志物以及具有成为治疗靶点的潜力,为HCC精准医疗提供新的见解。

【Abstract】The long-term survival rate of patients with hepatocellular carcinoma (HCC) is poor, and drug efficacy is an important factor affecting clinical prognosis. N6-methyladenosine (m6A) modification is the most abundant modification in eukaryotic RNA, which can affect the occurrence and development of HCC and drug efficacy by regulating cancer-related biological functions. However, the role of m6A modification in HCC drug treatment has not been fully elucidated. Therefore, the biological functions of different regulatory members of the m6A modification process (methyltransferase, demethyltransferase and binding protein) in HCC drug treatment were illustrated, proposing that regulatory members of the m6A modification process can be used as biomarkers for HCC prognosis evaluation and have the potential to become therapeutic targets and providing novel insights for HCC precision medicine.

肝细胞癌(hepatocellular carcinoma,HCC)是最常见的恶性肿瘤之一,占所有原发性肝癌患者的75%以上,其发病率在全球恶性肿瘤中居第6位,病死率居第3位[1]。既往HCC的治疗手段主要为局部措施,包括手术切除、肝移植、局部消融等。但大部分患者被发现时已处于中晚期,无法接受根治性治疗,5年生存率小于20%[2]。近年来,随着生物医学的进步,系统治疗为这一类中晚期患者带来了新的曙光,然而其总体生存率仍然不佳[3]。因此,为HCC患者开发更有效的治疗方法刻不容缓。

随着表观遗传学研究的不断深入,RNA修饰开始受到人们的关注,成为近年来较为火热的研究领域。RNA修饰中甲基化修饰是一种十分普遍的修饰,其中N6-甲基腺嘌呤(N6-methyladenosine,m6A)修饰已被证明是真核生物RNA中最丰富的修饰,其调节成员的异常与HCC等多种人类恶性肿瘤有关[4]。研究表明,HCC中m6A的总体水平及调节成员的表达均为异常,且与临床预后相关,此外,m6A修饰调节成员可以上调肝脏脂肪生成基因表达,在肝病中发挥着至关重要的作用[5]。……
