Seminal vesicles are novel sites of luteinizing hormone/human chorionic gonadotropin-receptor gene expression
LH/hCG receptors male accessory organs gonadotropins
2009/2/17
The hypothesis that rat seminal vesicles may contain luteinizing hormone (LH)/human chorionic gonadotropin (hCG) receptors was tested by means of a number of different techniques. Northern blotting ...
Testis factors that may regulate gene expression: evidence from a patient with Kartagener's syndrome
Kartagener’s syndrome infertility sperm ultrastructure flagella
2009/2/13
Patients with Kartagener's syndrome characteristically have immotile cilia and flagella. Ultrastructural analysis of the efferent ducts of the patient described in this report revealed that the ci...
Gene expression in the aging brown Norway rat epididymis
Gene expression aging brown Norway rat epididymis
2009/2/13
The mammalian epididymis is the site where spermatozoa are matured and then stored. Though many studies have described epididymal functions and their regulation, little is known about how aging af...
Proacrosin gene expression in rat spermatogenic cells
Testis sperm development meiosis acrosome germ
2009/2/12
Mammalian proacrosin gene expression was considered to be exclusively postmeiotic until recent studies detected the presence of proacrosin mRNA in mouse pachytene spermatocytes. To determine if rat ...
Testosterone feedback on gonadotropin secretion and gene expression in transgenic mice expressing human growth hormone gene
Luteinizing hormone follicle-stimulating hormone
2009/2/12
To determine the effects of testosterone on the regulation of gonadotropins in metallothionein-1/human growth hormone (MT/hGH) transgenic mice, basal and gonadotropin-releasing hormone (GnRH)-stim...
Identification and localization of copper-zinc superoxide dismutase gene expression in rat testicular development
Identification localization copper-zinc superoxide dismutase gene rat testicular development
2009/2/12
Reactive oxygen species are highly toxic agents that appear to have an important role in male infertility. In order to understand the potential for the testis to be protected from reactive oxygen, t...
Protein and gene expression of nitric oxide synthase isoforms I and III in the rat penile shaft
Protein gene expression nitric oxide synthase penile shaft
2008/12/26
Nitric oxide synthase (NOS) plays a key role in penile smooth muscle relaxation through the regulation of nitric oxide (NO). NO is a major neurotransmitter in the autonomic nervous system, and alter...

Osteopontin gene expression Holstein bull reproductive tract
2008/12/25
The objective of this study was to localize gene expression of osteopontin in the Holstein bull reproductive tract using Northern blot analysis and in situ hybridization. For Northern blot analysi...
Age-related decrease in hypothalamic gonadotropin-releasing hormone（GnRH）gene expression, but not pituitary responsiveness to GnRH, in the male Brown Norway rat
Age-related decrease hypothalamic gonadotropin-releasing hormone（GnRH）gene expression pituitary responsiveness GnRH male
2008/12/25
As is the case in humans, aging male Brown Norway (BN) rats exhibit both primary and secondary (hypothalamic/pituitary) testicular failure. We hypothesized that secondary testicular failure in aging...
Receptor Isoform and Ligand-Specific Modulation of Dihydrotestosterone-Induced Prostate Specific Antigen Gene Expression and Prostate Tumor Cell Growth by Estrogens
Androgen receptor androgens estrogen receptor
2008/12/23
Androgens via the androgen receptor (AR) play crucial roles in prostate physiology and pathophysiology. These androgen actions can be either inhibited or potentiated by estrogens. The mechanisms of ...
Gene Expression in Prostate Cancer Cells Treated With the Dual 5 Alpha-Reductase Inhibitor Dutasteride
