N6-methyladenine(m 6A)has been identified as the most abundant, common and conserved internal RNA modification.RNA m 6A can couple different levels of gene regulation and may play an important role in epigenetic regulation(such as RNA splicing, translation, stabilization, and ectopic). Studies have shown that RNA m 6A methylation is an important factor in pubertal sexual development.The abundance of RNA m 6A methylation changed with the progression of pubertal development.The abnormalities of RNA m 6A methylation can lead to dysfunction of hypothalamic gonadotropin-releasing hormone(GnRH)neuronal networks.Those genes affected by RNA m 6A methylation may be critical targets in regulating puberty initiation.The review summarizes the research progress between RNA m 6A methylation and pubertal sexual development to provide the evidence to discover new therapeutic targets and improve the prognosis of the disease.
