Effects of curcumin on canine semen parameters and expression of NOX5 gene in cryopreserved spermatozoa
Canine seminal plasma contains antioxidant enzymes to protect sperm against internally generated ROS. These enzymes are removed from seminal plasma during the process of cryopreservation. The freezing/thawing process can cause some morphological and functional changes via ice crystallization and osmolality imbalance. The present study was conducted to evaluate the effects of curcumin supplement...
متن کاملProteasomes in human spermatozoa.
In the present study we describe the localization of proteasomes in human spermatozoa by means of immunolabelling with different monoclonal and polyclonal antibodies detected by confocal microscopy. Western blotting confirmed the specificity of the antibodies and has shown that proteasomes are present in spermatozoa and in seminal fluid. In spermatozoa proteasomes are concentrated in the neck r...
متن کاملSurface glycoproteins of human spermatozoa.
The surface membrane glycoprotein composition of human spermatozoa has been studied by introducing radioactive label into galactosyl (Gal) and N-acetylgalactosaminyl (GalNAc) residues by using the galactose oxidase/NaB3H4 method. Triton X-100 extracts and Triton X-100-resistant cytoskeletal residues were subjected to analysis by polyacrylamide gel electrophoresis. The distribution of the radiol...
متن کاملAdriamycin induces H2AX phosphorylation in human spermatozoa.
AIM To investigate whether adriamycin induces DNA damage and the formation of gammaH2AX (the phosphorylated form of histone H2AX) foci in mature spermatozoa. METHODS Human spermatozoa were treated with adriamycin at different concentrations. gammaH2AX was analyzed by immunofluorescent staining and flow cytometry and double-strand breaks (DSB) were detected by the comet assay. RESULTS The ne...
متن کاملProgesterone receptors on human spermatozoa.
Progesterone, primarily recognized as a female steroid hormone, is reported to affect several sperm functions especially capacitation, motility and acrosome reaction. These effects of progesterone on the spermatozoa are mediated via the progesterone binding sites/progesterone receptor (PR) on the acrosomal membrane. These receptors in response to progesterone increase the intercellular Ca2+ lev...
