Abstract

The rapidly emerging prevalence of type 2 diabetes mellitus (T2DM) and its associated complications have formed an increasingly serious threat to human life and health. Therefore, there is an urgent requirement to investigate the pathogenesis of T2DM and its complications, which will be conducive to discovering effective drugs for prevention and treatment. N6-methyladenosine (m6A) methylation is the most abundant and prevalent epigenetic modification of mRNA in mammals. m6A methylation is a dynamically reversible epigenetic transcriptome modification process that is jointly regulated by methyltransferases, demethylases and methylated reading proteins, which control the fate of target mRNAs through influencing splicing, translation and decay. Recent studies have revealed that m6A methylation plays an important role in β cellular function, insulin sensitivity and glycolipid metabolism. In this review, we summarized the current roles of m6A methylation in T2DM and T2DM-related complications such as diabetes nephropathy (DN), diabetes cardiovascular disease (DCD) and diabetes retinopathy (DR). Additionally, we sought the potential mechanism of m6A in T2DM and related complications, which may provide a rationale and strategy for potential therapeutic targeting of T2DM and its complications.

M6a 甲基化:控制 2 型糖尿病及其并发症发展的新途径
2 型糖尿病(T2DM)及其相关并发症的发病率迅速上升,已对人类的生命和健康构成日益严重的威胁。因此,研究 T2DM 及其并发症的发病机制,有利于发现有效的预防和治疗药物,已成为当务之急。N6-甲基腺苷(m6A)甲基化是哺乳动物体内mRNA最丰富、最普遍的表观遗传修饰。m6A甲基化是一个动态可逆的表观遗传转录组修饰过程,由甲基转移酶、去甲基化酶和甲基化阅读蛋白共同调控,通过影响剪接、翻译和衰变来控制目标mRNA的命运。最近的研究发现,m6A 甲基化在 β 细胞功能、胰岛素敏感性和糖脂代谢中发挥着重要作用。在这篇综述中,我们总结了目前 m6A 甲基化在 T2DM 和 T2DM 相关并发症(如糖尿病肾病(DN)、糖尿病心血管疾病(DCD)和糖尿病视网膜病变(DR))中的作用。此外,我们还探讨了 m6A 在 T2DM 及其相关并发症中的潜在作用机制,从而为 T2DM 及其并发症的潜在靶向治疗提供理论依据和策略。
