“…Growing evidence suggests that miRNAs play an epigenetic role in many physiological processes through regulating multiple target genes in post‐transcriptional process, including development, cell proliferation (Clotaire, Du, Wei, Yang, & Hua, ), differentiation (Gao et al, ) and apoptosis (Capra et al, ). Several miRNAs have been identified in spermatozoa that have implications as critical regulators of apoptosis (Capra et al, ; Dai et al, ; Lv et al, ; Ma et al, ). Apoptosis regulates spermatogenesis (Wang, Li, Gong, Zhao, & Wu, ) and spontaneous programmed cell death in mature spermatozoa (Aitken & Baker, ; Engel, Springsguth, & Grunewald, ).…”
