Melatonin is an endocrine neurohormone secreted by pinealocytes in the pineal gland. It exerts diverse physiological effects, such as circadian rhythm regulator and antioxidant. However, the functional importance of melatonin in spermatogenesis regulation remains unclear. The objectives of this study are to: (1) detect melatonin affection on miRNA expression profiles in GC-1 spg cells by miRNA deep...
Polycystic ovary syndrome (PCOS) causes female subfertility with ovarian disorders and may be associated with increased rate of early-pregnancy failure. Rat PCOS models were established using letrozole to understand the uterine pathogenesis of PCOS. The differential expression of microRNAs (miRNAs) was observed in rat uterus with PCOS. After estrous cycles were disrupted, significantly abnormal ovarian...
Inhibins play important roles in normal gonadal function, including regulation of proliferation, differentiation, and steroidogenesis of Leydig and Sertoli cells via paracrine and autocrine processes. In adult males, circulating inhibin levels are correlated with fertility by regulating the number of Sertoli cells, total sperm count, and testicular volume. Given this important role, inhibin-α subunit...
