Sperm Proteome Maturation in the Mouse Epididymis
In mammals, transit through the epididymis, which involves the acquisition, loss and modification of proteins, is required to confer motility and fertilization competency to sperm. The overall dynamics of maturation is poorly understood, and a systems level understanding of the complex maturation process will provide valuable new information about changes occurring during epididymal transport. ...
متن کاملSperm-associated retroviruses in the mouse epididymis.
Sperm adsorbed with retrovirus particles were recovered from the epididymis of apparently normal male mice. Epididymal semen from all four mouse strains examined was positive for retrovirus (10(5) to 10(8) particles per microgram of protein) indicating that epididymal fluids and sperm may be important vehicles for murine retrovirus spread. Immunoblot analyses revealed that the banding patterns ...
متن کاملMaturation of sperm volume regulation in the rat epididymis.
Sperm maturation in the epididymis may involve differences between mature and immature spermatozoa in their volume regulatory osmolyte response. Spermatozoa obtained from the rat caput and cauda epididymidis were examined for their ability to regulate volume after transfer from in situ epididymal osmolality (measured to be 343 +/- 13 and 365 +/- 19 mmol kg(-1), respectively) to that of the fema...
متن کاملRegion-specific localization of IMDS-60 protein in mouse epididymis and its relationship with sperm maturation.
Spermatozoa acquire forward motility and fertilizing capacity during their transit through the epididymis. This maturation process involves modifications of the sperm surface by different proteins secreted by a series of specialized regions in the epididymal epithelium. Previously, our lab has reported IMDS-60 gene, which is highly expressed in mouse corpus and cauda epididymidis. Here, to perf...
متن کاملIncrease in the concentration of major boar sperm surface proteins during maturation in the epididymis.
High-resolution two-dimensional polyacrylamide gel electrophoresis analyses have indicated that several major boar sperm plasma membrane polypeptides (PMPs) increased in concentration during maturation in the epididymis. To investigate this further, monoclonal antibodies (MAbs) to two of these PMPs/glycoproteins referenced as 4.85 and 5.0 and polyclonal antisera (PCA) raised against PMP 5.0 wer...
