The epidemic of diabetes mellitus (DM) necessitates the development of novel therapeutic and preventative strategies to attenuate complications of this debilitating disease. Diabetic cardiomyopathy (DCM) is a frequent disorder affecting individuals diagnosed with DM characterized by left ventricular hypertrophy, diastolic and systolic dysfunction and myocardial fibrosis in the absence of other heart diseases. Progression of DCM is associated with impaired cardiac insulin metabolic signaling, increased oxidative stress, impaired mitochondrial and cardiomyocyte calcium metabolism, and inflammation. Various non-coding RNAs, such as microRNAs (miRNAs) and long non-coding RNAs (lncRNAs), as well as their target genes are implicated in the complex pathophysiology of DCM. It has been demonstrated that miRNAs and lncRNAs play an important role in maintaining homeostasis through regulation of multiple genes, thus they attract substantial scientific interest as biomarkers for diagnosis, prognosis and as a potential therapeutic strategy in DM complications. This article will review the different miRNAs and lncRNA studied in the context of DM, including type 1 and type 2 diabetes and the contribution of pathophysiological mechanisms including inflammatory response, oxidative stress, apoptosis, hypertrophy and fibrosis to the development of DCM .
糖尿病(DM)的流行需要开发新的治疗和预防策略,以减轻这种使人衰弱的疾病的并发症。糖尿病心肌病(DCM)是一种常见的疾病,影响诊断为 DM 的个体,其特征是左心室肥厚、舒张和收缩功能障碍以及心肌纤维化,而没有其他心脏病。DCM 的进展与心脏胰岛素代谢信号受损、氧化应激增加、线粒体和心肌细胞钙代谢受损以及炎症有关。各种非编码 RNA,如 microRNAs(miRNAs)和长非编码 RNA(lncRNAs)及其靶基因,都与 DCM 的复杂病理生理学有关。已经证明,miRNAs 和 lncRNAs 通过调节多个基因在维持内稳态方面发挥着重要作用,因此它们作为 DM 并发症的诊断、预后和潜在治疗策略的生物标志物引起了广泛的科学关注。本文将综述在 DM 背景下研究的不同 miRNAs 和 lncRNA,包括 1 型和 2 型糖尿病,以及病理生理机制的贡献,包括炎症反应、氧化应激、细胞凋亡、肥大和纤维化,对 DCM 的发展。
