Abstract:

MicroRNAs (miRNAs) have emerged as key regulators of diverse biological processes, including cell proliferation, differentiation, apoptosis, and metabolism. They are also actively involved in the reproductive and developmental processes of organisms. Among the let-7 family, miR-202 stands out owing to its high conservation across different species, implying the potential shared functions and regulatory roles. Substantial evidence from numerous studies underscores the involvement of miR-202 in a wide range of pathophysiological processes. Notably, it exerts significant inhibitory effects on tumor cell proliferation, migration, and invasion. Moreover, miR-202 plays a critical role in modulating the differentiation of T cell and exhibits the implications in the regulation of neurodevelopment and neurodegenerative diseases. The increasing evidence have indicated that miR-202 plays a crucial role in gamete development and the regulation of reproductive physiology. In this article, we review the regulatory roles of miR-202 in key reproductive processes, namely spermatogenesis, follicle development, and reproductive endocrine regulation.
