Interleukin-6 enhances the fertilizing capacity of human sperm by increasing capacitation and acrosome reaction
Interleukin-6 enhances human sperm acrosome reaction
2009/2/12
The effects of human recombinant interleukin-6 (IL-6) on human sperm penetration of zona-free hamster ova (SPA) and human sperm cell capacitation and acrosome reaction were investigated. IL-6 at h...
Sperm surface proteins after capacitation. Expression of vitronectin on the spermatozoan head and laminin on the sperm tail
Sperm surface proteins vitronectin spermatozoan head laminin sperm tail
2009/2/11
Several integrins recognize as ligands proteins containing the Arg-Gly-Asp (RGD) sequence, such as fibronectin, vitronectin, and laminin. It has been previously demonstrated that oligopeptides con...
Sperm surface fibronectin. Expression following capacitation
Sperm surface fibronectin Expression capacitation
2009/2/10
The Arg-Gly-Asp (RGD) amino acid sequence plays a role in many cell-to-cell and cell-to-matrix adhesion systems, as a recognition sequence for cell membrane receptors termed integrins. Receptors of ...
Influence of bovine follicular and oviduct fluids on sperm capacitation in vitro
bovine follicular oviduct fluids sperm capacitation
2009/2/7
The ability of bovine follicular fluid (FF) and oviduct fluid (ODF) to capacitate sperm was determined. At concentrations of greater than 20%, both FF and ODF capacitated sperm within 4 hours, but a...
Lipid transfer activity in human follicular fluid：relation to human sperm capacitation
sperm capacitation acrosome reaction lipid transfer cholesteryl ester
2009/2/6
A potentially important event during sperm capacitation is the loss of sperm membrane cholesterol. Although the exact mechanisms mediating this loss are not known, albumin and high density lipopr...
Sialyglycoconjugates release during in vitro capacitation of human spermatozoa
human sperm capacitation glycoconjugates
2009/2/6
Modifications of the human sperm surface during incubation in capacitating conditions were studied by radiolabeling terminal sialic acid residues of cell surface glycoconjugates using the sodium met...
Capacitation and Induction of the Acrosome Reaction in Bull Spermatozoa With Norepinephrine
Catecholamines bovine
2008/12/30
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 s...
The role of glucose in supporting motility and capacitation in human spermatozoa
Acrosome reaction ATP hamster oocyte penetration
2008/12/29
Glucose has been reported to be beneficial to human sperm for optimal capacitation and fertilization, although it is unclear whether glucose is required for providing extra metabolic energy through gl...
Semenogelin, the main protein of semen coagulum, inhibits human sperm capacitation by interfering with the superoxide anion generated during this process
Protein tyrosine phosphorylation prostate-specific antigen
2008/12/29
Semenogelin (Sg), the major protein of the human semen coagulum, is present at high concentrations in seminal vesicle secretions. It is degraded by the prostate-specific antigen (PSA) to generate pe...
The cyclic GMP-specific phosphodiesterase inhibitor, sildenafil, stimulates human sperm motility and capacitation but not acrosome reaction
cyclic GMP-specific phosphodiesterase inhibitor sildenafil human sperm motility capacitation
2008/12/25
Capacitation is the series of transformations that spermatozoa undergo in the female genital tract in order to bind to the zona pellucida, initiate the acrosome reaction, and fertilize an egg. Cyc...
Effects of accessory sex gland fluid on viability, capacitation, and the acrosome reaction of cauda epididymal bull spermatozoa
sex gland viability capacitation reaction bull spermatozoa
2008/12/25
The effect of accessory sex gland fluid (AGF) on viability and acrosomal integrity of spermatozoa was examined with cauda epididymal spermatozoa and AGF from the same Holstein bull (n = 6). Surgical...
