The CatSper channel modulates boar sperm motility during capacitation.
The cation channel of sperm (CatSper) comprises four transmembrane subunits specifically expressed in human, equine, murine and ovine spermatozoa, apparently implicated in capacitation, hyperactivation and acrosome exocytosis. Western blotting and immunocytochemistry showed hereby that CatSper subunits are also present in boar spermatozoa, primarily over the sperm neck, tail and cytoplasmic dro...
متن کاملEffEct of caffEinE on paramEtErs of ram spErm motility
The goal of this study was to examine the effect of caffeine on motility parameters of cooling-stored ram sperm – total motility and progressive movement. Caffeine is a cyclic nucleotide phosphodiesterase inhibitor, which can affect sperm motility. The semen was kept at 4 ̊C for several days. Caffeine was added to fresh ram semen diluted in Triladyl at concentrations of 1, 2 and 4 mmol.l -1 ever...
متن کاملFactors influencing boar sperm cryosurvival.
Optimal sperm cryopreservation is a prerequisite for the sustainable commercial application of frozen-thawed boar semen for AI. Three experiments were performed to identify factors influencing variability of postthaw sperm survival among 464 boar ejaculates. Sperm-rich ejaculate fractions were cryopre-served using a standard freezing-thawing procedure for 0.5-mL plastic straws and computer-cont...
متن کاملEvaluation of Boar Sperm Viability by MTT Reduction Assay in Beltsville Thawing Solution Extender*
MTT (3-(4, 5-dimethyl thiazol-2-yl)-2, 5-diphenyl tetrazolium bromide) reduction assay is a method that validates the viability of an active cell. Dehydrogenase in mitochondria converts yellow colored insoluble tetrazolium salt to purple colored watersoluble formazan. Sperm also have mitochondria in the midpiece, therefore sperm viability could be evaluated by MTT reduction assay. Several studi...
