The presence of a high-Km hexokinase activity in dog, but not in boar, sperm.
The presence of a high-Km hexokinase activity was tested in both dog and boar spermatozoa. Hexokinase kinetics from dog extracts showed the presence of a specific activity (dog-sperm glucokinase-like protein, DSGLP), in the range of glucose concentrations of 4-10 mM, whereas boar sperm did not show any DSGLP activity. Furthermore, dog-sperm cells, but not those of boar, showed the presence of a...
متن کاملMolecular dissection of IZUMO1, a sperm protein essential for sperm-egg fusion.
Although the membrane fusion of spermatozoon and egg cells is the central event of fertilization, the underlying molecular mechanism remains virtually unknown. Gene disruption studies have showed that IZUMO1 on spermatozoon and CD9 on oocyte are essential transmembrane proteins in sperm-egg fusion. In this study, we dissected IZUMO1 protein to determine the domains that were required for the fu...
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 کاملAlkaline Phosphatase in Serum is a Marker of Human Toxocariasis
Background: The present study was carried out on the human population of Kashmir valley to evaluate the status of the biochemical parameters of infected population. Materials and Methods: Blood samples were collected from 514 individuals, 298 (57.97%) males and 216 (42.02%) females, 187 (36.38%) were found sero-positive for human toxocariasis. Results: Alkaline phosphatase level was found highe...
متن کاملOocyte-triggered dimerization of sperm IZUMO1 promotes sperm–egg fusion in mice
Sperm-egg fusion is indispensable for completing mammalian fertilization. Although the underlying molecular mechanisms are poorly understood, requirement of two spermatozoon factors, IZUMO1 and SPACA6, and two oocyte factors, CD9 and the IZUMO1 counter-receptor JUNO, has been proven by gene disruption, and the binding of cells to an oocyte can be reconstituted by ectopic expression of IZUMO1. H...
