Crosstalk between ubiquitin ligases and ncRNAs drives cardiovascular disease progression.

Cardiovascular diseases (CVDs) are multifactorial chronic diseases and have the highest rates of morbidity and mortality worldwide. The ubiquitin-proteasome system (UPS) plays a crucial role in posttranslational modification and quality control of proteins, maintaining intracellular homeostasis via degradation of misfolded, short-lived, or nonfunctional regulatory proteins. Noncoding RNAs (ncRNAs, such as microRNAs, long noncoding RNAs, circular RNAs and small interfering RNAs) serve as epigenetic factors and directly or indirectly participate in various physiological and pathological processes.

Ferroptosis in Cancer Progression: Role of Noncoding RNAs.

Ferroptosis is a novel form of programmed cell death, and it is characterized by iron-dependent oxidative damage, lipid peroxidation and reactive oxygen species accumulation. Notable studies have revealed that ferroptosis plays vital roles in tumor occurrence and that abundant ferroptosis in cells can inhibit tumor progression. Recently, some noncoding RNAs (ncRNAs), particularly microRNAs, long noncoding RNAs, and circular RNAs, have been shown to be involved in biological processes of ferroptosis, thus affecting cancer growth.

Critical functions of microRNA-30a-5p-E2F3 in cardiomyocyte apoptosis induced by hypoxia/reoxygenation.

The high-mortality rate of cardiovascular diseases (CVDs) is associated with the myocardial ischemia and reperfusion (I/R). Recent investigations have revealed that microRNAs (miRNAs) exert vital functions in the apoptosis of cardiomyocyte cell. Nevertheless, the potential role of miR-30a-5p in the regulation of cardiomyocyte cell apoptosis needs to be illuminated.
