Abstract

MicroRNA (miRNA) are small, noncoding RNA molecules that play pivotal roles in gene expression, various biological processes, and development of disease. MiRNAs exhibit distinct expression patterns depending on time points and tissues, indicating their relevance to the development, differentiation, and somatic growth of organisms. MiRNAs are also involved in puberty onset and fertility. Although puberty is a universal stage in the life cycles of most organisms, the precise mechanisms initiating this process remain elusive. Genetic, hormonal, nutritional, environmental, and epigenetic factors are presumed contributors. The intricate regulation of puberty during growth also suggests that miRNAs are involved. This study aims to provide insight into the understanding of miRNAs roles in the initiation of puberty by reviewing the existing research.
