Extracellular vesicles (EVs) derived from parental cells could communicate with neighboring or distant recipient cells. The components in EVs, especially non-coding RNAs, including microRNAs, long non-coding RNAs, and circular RNAs, could regulate the functions of the recipient cells. Meanwhile, EVs could also be used as valuable biomarkers and drug delivery carriers. Moreover, environmental toxicants may alter EVs components and regulate EVs-mediated pathogenesis of various diseases. In this review, we mainly summarized the roles of EV-derived non-coding RNAs in the regulation of cell dysfunctions in various adverse pregnancy outcomes, such as preeclampsia (PE), gestational diabetes mellitus (GDM), and miscarriage. Moreover, the effects of environmental toxicants on the components and functions of EVs, as well as on their regulatory roles in these diseases, were also discussed. [ABSTRACT FROM AUTHOR]

Reperfusion therapy is the most effective treatment for acute myocardial infarction. However, reperfusion itself can also cause cardiomyocytes damage. Pyroptosis has been shown to be an important mode of myocardial cell death during ischemia-reperfusion. Non-coding RNAs (ncRNAs) play critical roles in regulating pyroptosis. The regulation of pyroptosis by microRNAs, long ncRNAs, and circular RNAs may represent a new mechanism of myocardial ischemia-reperfusion injury. This review summarizes the currently known regulatory roles of ncRNAs in myocardial ischemia-reperfusion injury and interactions between ncRNAs. Potential therapeutic strategies using ncRNA modulation are also discussed. [ABSTRACT FROM AUTHOR]

Noncoding RNAs (ncRNAs) do not participate in protein-coding. Ferroptosis is a newly discovered form of cell death mediated by reactive oxygen species and lipid peroxidation. Recent studies have shown that ncRNAs such as microRNAs, long noncoding RNAs, circular RNAs, and ferroptosis are involved in the occurrence and development of osteosarcoma (OS). Studies have confirmed that ncRNAs participate in the development of OS by regulating the ferroptosis. However, systematic summary on this topic are still lacking. This review summarises the potential role of ncRNAs in the diagnosis, treatment, drug resistance, and prognosis of OS and the basis for diagnosing, preventing, and treating clinical OS and developing effective drugs. This review summarises the latest research progress on ncRNAs that regulate ferroptosis in OS, attempts to clarify the molecular mechanisms by which ncRNAs regulate ferroptosis in the pathogenesis of OS, and elaborates on the involvement of ferroptosis in OS from the perspective of ncRNAs. [Display omitted] • NcRNAs play an important role in the treatment, diagnosis, prognosis, and drug resistance of osteosarcoma. • Ferroptosis involving ncRNAs provides a new direction for the pathogenesis of osteosarcoma. • NcRNAs may act as a hub for regulating the ferroptosis of osteosarcoma with other forms of cell metabolism and death. • The expression of ncRNAs related with ferroptosis is correlated with immune checkpoint, which can be explored as a new idea of immunotherapy for osteosarcoma.
