Apoptosis and necrosis in human ejaculated spermatozoa.
BACKGROUND Features of both apoptosis and necrosis have been reported in ejaculated human spermatozoa. This study examines the relative contribution of these two modes of cell death to the demise of these terminally differentiated cells. METHODS Sperm fractions were prepared from aliquots of semen samples from young normozoospermic donors by simple washing from seminal plasma, by discontinuou...
متن کاملThe expression and significance of CATSPER1 in human testis and ejaculated spermatozoa.
AIM To investigate the distribution of cation channel of sperm 1 (CATSPER1) protein and the presence of CATSPER1 mRNA in human testis and ejaculated spermatozoa. The influence of anti-human CATSPER1 antibody upon human sperm motility was used to evaluate the function of human CATSPER1 and to estimate its possible use as a target for immunocontraception. METHODS Human ejaculated sperm from nor...
متن کاملIdentification of bovine doppel protein in testis, ovary and ejaculated spermatozoa.
Doppel (Dpl) protein is a recently identified prion-like protein. Although Dpl might be expressed in the brain after prion gene deletion, in both human and mice Dpl is normally expressed only in testis and spermatozoa, where it appears to be involved in male fertility. Little information is available so far about the expression pattern of Dpl in bovines, thus, hampering possible research on the...
متن کاملOligozoospermia and heat-shock protein expression in ejaculated spermatozoa.
BACKGROUND Heat-shock protein A2 (HspA2) is correlated with sperm maturity, function and fertility, and a dysfunctional expression of such a gene results in abnormal spermatogenesis. The purpose of this study was to compare HspA2 gene expression in spermatozoa from oligozoospermic men and normozoospermic controls. METHODS Semen was obtained and analysed according to World Health Organization ...
متن کاملIs prnt a Pseudogene? Identification of Ram Prt in Testis and Ejaculated Spermatozoa
A hallmark of prion diseases or transmissible spongiform encephalopaties is the conversion of the cellular prion protein (PrP(C)), expressed by the prion gene (prnp), into an abnormally folded isoform (PrP(Sc)) with amyloid-like features that causes scrapie in sheep among other diseases. prnp together with prnd (which encodes a prion-like protein designated as Doppel), and prnt (that encodes th...
