Localization of cellular retinol-binding protein and cellular retinoic acid-binding protein in the rat testis and epididymis
cellular retinol-binding protein cellular retinoic acid-binding protein rat testis
2009/2/20
The distribution of cellular retinol-binding protein (CRBP) and cellular retinoic acid-binding protein (CRABP) in rat testis and epididymis was examined by the peroxidase-antiperoxidase immunolocali...
Rat Testicular Phospholipase A2 Activity：pH Optima, Its Cellular and Subcellular Distribution in the Gonad, and Some Factors That May Modulate Its Activity
rat testicular phospholipase A2 activity pH optima localization control
2009/2/19
A sensitive radiometric assay was developed for detecting phospholipase A1 and A2 (PLA1 and A2) activity. Four to five times more PLA2 activity was observed in rat testes than PLA1 activity. Two PLA...
II. Characterization and development of the regional- and cellular-specific abnormalities in the epididymis of mice with beta-hexosaminidase A deficiency
II. Characterization regional- and cellular-specific abnormalities epididymis mice with beta-hexosaminidase A deficiency
2009/2/18
Beta-hexosaminidase (Hex) is a lysosomal enzyme that exists as two isoenzymes: Hex A (subunit structure alphabeta) and Hex B (betabeta). Its presence in the testis and epididymis suggests importan...
Sodium chlorate induces undersulfation of cellular proteoglycans and increases in FSH-stimulated estradiol production in immature rat Sertoli cells
Sodium chlorate cellular proteoglycans FSH-stimulated estradiol production immature rat Sertoli cells
2009/2/18
The functional influence of cell proteoglycan (PG) undersulfation on estradiol synthesis by immature rat Sertoli cell cultures was investigated by using sodium chlorate, an inhibitor of the active s...
Hormonal regulation of spermatogenesis in the hypophysectomized rat：FSH maintenance of cellular viability during pubertal spermatogenesis
Testis testosterone hypohysectomy cellviability
2009/2/17
The potential for follicle-stimulating hormone (FSH) to promote germ-cell survival and the cellular sites of FSH action were studied using a gonadally maturing (pubertal), hypophysectomized (Hx) rat...
The cellular mechanisms of corticotropin-releasing hormone（CRH）-stimulated steroidogenesis in mouse Leydig cells are similar to those for LH
MA-b Progesterone testosterone
2009/2/17
Previous reports have demonstrated that corticotropin-releasing hormone (CRH) treatment of primary cultures of mouse Leydig cells and MA-10 mouse Leydig tumor cells results in a dose-dependent sti...
Testosterone and spermatogenesis: evidence that androgens regulate cellular secretory mechanisms in stage VI-VIII seminiferous tubules from adult rats
Testosterone spermatogenesis androgens regulate cellular secretory mechanisms adult rats
2009/2/13
The aim of this study was to investigate the effect of testosterone manipulation on the quantitative synthesis and secretion of a number of specific proteins produced by seminiferous tubules (ST) ...
Correlation between the rate of lipid peroxidation and cellular maturity as measured by creatine kinase activity in human spermatozoa
Spermatogenesis sperm development oligospermia male fertility
2009/2/12
We have demonstrated previously that creatine kinase (CK) activity is a measure of cellular maturity and fertilizing potential in human spermatozoa. In the present work we have examined whether th...
Sertoli cell secreted growth factor. Cellular origin, paracrine and endocrine regulation of secretion
Sertoli cell Cellular origin paracrine endocrine regulation secretion
2009/2/12
Rat and human Sertoli cells in culture secrete a growth factor, Sertoli cell secreted growth factor (SCSGF). The aims of the present study were (1) to evaluate other testicular cell types as additio...
Cellular regulation of follicle-stimulating hormone（FSH）binding in rat seminiferous tubules
rat testis FSH binding germ cell-Sertoli cell interactions
