The myocardial infarction is the main cause of morbidity and mortality in cardiovascular diseases around the world. Although the timely and complete reperfusion via Percutaneous Coronary Intervention (PCI) or thrombolysis have distinctly decreased the mortality of myocardial infarction, reperfusion itself may lead to supererogatory irreversible myocardial injury and heart function disorders, namely ischemia-reperfusion (I/R) injury. Extensive studies have indicated that non-coding RNAs (ncRNAs), including microRNAs (miRNAs), long noncoding RNAs (lncRNAs) and circular RNAs (circRNAs), play important roles in the progress of myocardial I/R injury, which is closely correlative with cardiomyocytes autophagy. Moreover, autophagy plays an important role in maintaining homeostasis and protecting cells in the myocardial ischemia reperfusion and cardiomyocyte hypoxia-reoxygenation (H/R) progress. In this review, we first introduced the biogenesis and functions of ncRNAs, and subsequently summarized the roles and relevant molecular mechanisms of ncRNAs regulating autophagy in myocardial I/R injury. We hope that this review in addition to develop a better understanding of the physiological and pathological roles of ncRNAs, can also lay a foundation for the therapies of myocardial I/R injury, and even for other related cardiovascular diseases.

Objective: Ischemia-reperfusion of the abdominal aorta often results in damage to distant organs, such as the heart and brain. This cellular heterogeneity within affected tissues complicates the roles of specific cell subsets in abdominal aorta occlusion model (AAO) injury. However, cell type-specific molecular pathology in the hippocampus after ischemia is poorly understood.

The abrupt and substantial elevation of intraocular pressure (IOP) in acute glaucoma induces retinal ischemia/reperfusion (I/R) injury, resulting in progressive retinal ganglion cell (RGC) death and irreversible visual impairment. PANoptosis, a form of regulated cell death consisting of pyroptosis, apoptosis and necroptosis, is reported to be involved in high IOP-induced RGC death. However, the precise mechanisms of RGC death remain unclear, and neuroinflammation is considered to play a vital role.

Stroke remains a leading cause of disability and mortality worldwide, with mitochondrial dysfunction closely linked to ischemic injury. This study explores the Norad-Pum2-Mff axis as a key regulator of mitochondrial function following ischemia-reperfusion (I/R) injury. Using an oxygen-glucose deprivation/reoxygenation (OGD/R) model, Mff protein levels were significantly elevated post-OGD/R, while mRNA levels remained unchanged, suggesting post-transcriptional regulation.

Redox imbalance, including excessive production of reactive oxygen species (ROS) caused by mitochondrial dysfunction and insufficient endogenous antioxidant capacity, is the primary cause of myocardial ischemia‒reperfusion (I/R) injury. In the exploration of reducing myocardial I/R injury, it is found that protecting myocardial mitochondrial function after reperfusion not only reduces ROS bursts but also inhibits cell apoptosis triggered by the release of cytochrome c. Additionally, nuclear factor erythroid 2-related factor 2 (Nrf2) is considered a potential therapeutic target for treating myocardial I/R injury by enhancing the cellular antioxidant capacity through the induction of endogenous antioxidant enzymes.

Purpose: Due to its increased volume, polycystic ovarian tissue is more prone to torsion than normal ovarian tissue. In treating ovarian torsion, detorsion is applied to ensure oxygenation of hypoxic tissues. However, the resulting oxygen radicals cause tissue damage.
