摘要:Abstract(#br)The acrosome reaction is the regulated exocytosis of mammalian sperm's single secretory granule, essential for fertilization. It relies on small GTPases, the cAMP binding protein Epac, and the SNARE complex, among other components. Here, we describe a novel tool to ...

摘要:Abstract(#br)In the fertilization process of sea stars, sperm is activated to go through the acrosome reaction before cell fusion. We focused on induction of the acrosome reaction as a key process in fertilization. Six species of sea stars were used in this study: Asterias amuren...

摘要:Abstract(#br)The sperm acrosome reaction occurs after the binding of the capacitated sperm to the egg zona pellucida. This study describes a novel mode of regulation of the sperm epidermal growth factor receptor (EGFR) under physiological conditions and its relevance to the acrosome reaction...

摘要:Abstract(#br)The present study was conducted to know the role of Nitric Oxide (NO ) on the acrosome reaction (AR) in Murrah buffalo ( Bubalus bubalis ) spermatozoa. Ejaculated buffalo spermatozoa were washed, suspended in sp-TALP media containing 6 mg BSA/mL and cell concentrat...

摘要:Abstract(#br)This study focuses on the effect of chemicals on acrosome reaction in elephant spermatozoa. Semen was collected at the Washington Park Zoo in Portland, Oregon, from an 11-yr-old Asian elephant by artificial vagina (7 ejaculates) and transported to Mahidol University...

摘要:Abstract(#br)Capacitated mammalian spermatozoa undergo a fusion response of their head plasma membrane and the outer acrosomal membrane leading to vesiculation classically known as acrosome reaction. Acrosome reaction occurs in response to various acrosome reaction inducers inclu...

摘要:... Theoretically, DNA damage should alter the special cellular functions of human spermatozoa, and lead to diminished acrosome reaction with reduced fertilization rates. Nevertheless, intracytoplasmic sperm injection (ICSI) has been reported to alleviate such negative outcom...

摘要:Abstract(#br)We have previously demonstrated the presence of active epidermal growth factor receptor (EGFR) and its involvement in sperm capacitation and the acrosome reaction; however, the mechanism of EGFR activation was not clear. We show here that the sperm EGFR can be transa...

摘要:Abstract(#br)Lead (Pb) exposure at high concentrations is associated with poor sperm quality, acrosome alterations, and low fertilization rate. Sperm capacitation and the acrosome reaction (AR) are required for successful fertilization. Actin polymerization is crucial for corre...

摘要:Abstract(#br)The effect of gamma-aminobutyric acid (GABA) on the bull sperm acrosome reaction was evaluated, and the interaction of progesterone, a physiologic inducer of the acrosome reaction, with the GABA receptor was explored. The acrosome reaction was stimulated by GABA i...
