The mouse sperm glycine receptor/chloride channel：cellular localization and involvement in the acrosome reaction initiated by glycine
mouse sperm glycine receptor/chloride channel cellular localization involvement glycine
2008/12/25
Previously, we reported that glycine initiates the in vitro acrosome reaction (AR) of porcine and human sperm by a mechanism that includes the glycine receptor/Cl- channel (GlyR) and that this recep...
Impact of Ca2+ Flux Inhibitors on Acrosome Reaction of Hamster Spermatozoa
Ca2+ Inhibitors Acrosome Reaction Hamster Spermatozoa
2008/12/24
Ca2+ plays a prominent role in the regulation of critical functions of spermatozoa, such as capacitation, acrosome reaction (AR), and fertilization. While there is consensus that Ca2+ is essential, ...
Acrosome Reaction Induced by Recombinant Human Zona Pellucida 3 Peptides rhuZP3a22176 and rhuZP3b177348 and Their Mechanism
Human sperm pertussis toxin intracellular calcium G protein calcium channel chlortetracycline
2008/12/24
To explore the biological characteristics of the recombinant zona pellucida 3 (ZP3) peptides of rhuZP3a22176 and rhuZP3b177348, we examined whether rhuZP3a22176 or rhuZP3b177348 trigger the acros...
Identification of Human HAPRIN Potentially Involved in the Acrosome Reaction
Sperm spermatozoa vesicle RBCC protein
2008/12/23
The acrosome reaction in sperm is an exocytotic event required for fertilization. Previously, we isolated a novel haploid–germ-cell–specific gene in the mouse; this gene, named haprin, encodes the R...
Activation of Protein Kinase A During Human Sperm Capacitation and Acrosome Reaction
Phosphodiesterases cyclic adenosine monophosphate calcium ionophore A23187 signal transduction
2008/12/15
Spermatozoa undergo a variety of changes during their life that are prerequisites to their maturation and ability to fertilize eggs. Mammalian sperm capacitation and acrosome reaction are regulated by...
Capacitation and Induction of the Acrosome Reaction in Bull Spermatozoa With Norepinephrine
Catecholamines bovine
2008/12/3
Identification of norepinephrine (NE) within the microenvironment of the bovine oviduct suggests a potential role for catecholamines in the events surrounding fertilization. Previous studies have ...

Identification of norepinephrine (NE) within the microenvironment of the bovine oviduct suggests a potential role for catecholamines in the events surrounding fertilization. Previous studies have ...
Induction of the acrosome reaction and zona-free hamster oocyte penetration by a bull with complete teratospermia versus a half brother with normal sperm
zona-free hamster oocyte penetration bull complete teratospermia
2008/12/1
A fertile bull producing normal sperm and a sterile half brother exhibiting 100% teratospermia were available to study an induced sperm acrosome reaction and oocyte penetration. Pedigree analysis in...
