Suppression of steroid receptor-chromatin interaction by inhibitors present in ammonium sulfate-fractionated rat testicular androgen receptor preparations
steroid receptor-chromatin interaction inhibitors present ammonium sulfate-fractionated rat
2009/2/23
Tritiated androgen receptor complex was partially purified by ammonium sulfate precipitation at 15 to 37% saturation from rat testicular or prostatic cytosols. A greater amount of prostatic tritiate...
Suppression of the proliferative response of the seminal vesicles to testosterone by inhibitors of prostaglandin synthesis. Testosterone, indomethacin, and proliferation in seminal vesicles
seminal vesicles testosterone prostaglandin synthesis
2009/2/19
Effects of indomethacin (1.25 mg/kg) and aspirin (20 mg/kg) on testosterone-induced (0.25 mg/rat), and of indomethacin on dihydrotestosterone-induced (0.25 mg/rat) mitotic activity of the seminal ...
The Effect of Inhibitors of Trypsin and Phospholipase A2 on the Penetration of Zona Pellucida-free Hamster Eggs by Acrosome-reacted Hamster Sperm
Trypsin Phospholipase A2 Penetration Zona Pellucida-free Hamster Eggs
2009/2/19
The involvement of a trypsin-like enzyme and a phospholipase A2 in hamster sperm-egg fusion was investigated. Previously acrosome-reacted sperm and zona pellucida-free eggs were incubated in a low...
The Effects of Cyclic Adenine Nucleotides, Phosphodiesterase Inhibitors, and Cauda Epididymidal Fluid on the Motility of Rat Epididymal Spermatozoa
spermatozoa motility epididymal rat
2009/2/19
Experiments were performed to determine whether the rat epididymis secretes a "forward-motility" factor(s) similar to that found by others in the bovine epididymis. Lumen content of the rat caput ...
Follicle-stimulating Hormone Receptor Binding Inhibitors in Human Seminal Plasma
FSH binding inhibition seminal plasma
2009/2/19
Human seminal plasma, freed of spermatozoa by centrifugation, inhibited binding of iodine-125 (125I)-hFSH to receptors in calf testes. Binding inhibition (BI) was seen in seminal plasma from intact ...
Detection of human glandular kallikrein, hK2, as its precursor form and in complex with protease inhibitors in prostate carcinoma serum
Monoclonal antibody prostate cancer cancer diagnostic
2009/2/17
Forms of human glandular kallikrein (kK2) in prostate carcinoma serum were identified using monoclonal antibodies specific for hK2 and prohK2. Recombinant mammalian hK2, prohK2, and prostate = speci...
Interactions of proteases and protease inhibitors in Sertoli-germ cell cocultures preceding the formation of specialized Sertoli-germ cell junctions in vitro
proteases and protease inhibitors Sertoli-germ cell specialized Sertoli-germ cell
2009/2/17
The biochemical mechanism(s) by which germ cells can form specialized junctions with Sertoli cells in the seminiferous epithelium at various stages of the spermatogenic cycle is unknown. This stud...
Rationale for using aromatase inhibitors to manage benign prostatic hyperplasia. Experimental studies
aromatase inhibitors prostatic hyperplasia Experimental studies
2009/2/7
Today, human benign prostatic hyperplasia (BPH) is considered primarily to be a disease of the stroma, in which estrogens are thought to play a considerable causative or permissive role. The growi...

2009/2/7
Surgical castration and estrogen therapy for prostate cancer were developed in 1941, and have been shown to improve both quality of life and survival. Little change in the therapeutics of prostate...
Impact of Ca2+ Flux Inhibitors on Acrosome Reaction of Hamster Spermatozoa
Ca2+ Inhibitors Acrosome Reaction Hamster Spermatozoa
2008/12/24
Ca2+ plays a prominent role in the regulation of critical functions of spermatozoa, such as capacitation, acrosome reaction (AR), and fertilization. While there is consensus that Ca2+ is essential, ...
