前列腺癌是目前全世界男性第二大癌症相关致死性疾病。近年来我国前列腺癌的发病率呈显著增长趋势,严重威胁老年男性生命健康。前列腺癌中TMPRSS2-ERG 基因融合现象十分常见,其在欧美人群中发生率高达50%,在亚洲人群中也占据约四分之一。TMPRSS2-ERG 基因融合导致 ERG 致癌蛋白异常高表达,ERG 致癌蛋白作为恶性促癌转录因子进一步激活下游一系列致癌基因及其表达的致癌蛋白,从而促进前列腺...
Gonadotropin binding to the adult Leydig cell activates a GTP binding protein that interacts with adenylate cyclase to increase cAMP production within the cell. The increased production of cAMP stim...
In hypophysectomized rats, 2 days after the administration of the cytotoxic drug ethane dimethyl sulphonate (EDS), the proliferative activity of Leydig cell precursors increased six-fold. Thus, fact...
The indazole-carboxylic acid derivative tolnidamine (TOL) has marked antispermatogenic activity in rats. Previous morphological and biochemical studies indicate that Sertoli cells are one of the tar...
The reciprocal influence between Leydig and Sertoli cells prepared from pig testis were studied by coculture of both types of cells in either plastic dishes or dishes coated with basement membrane...
The effects of synthetic salmon calcitonin on primary Sertoli cell-enriched cultures and on an established cell line (TM4 cells, derived from immature mouse Sertoli cells) were studied. Synthetic ...
Studies demonstrating calcitonin receptors on Leydig cells have suggested that these cells may be one of the many sites affected by this peptide. To investigate this possibility, the effect of syn...
To understand the involvement of polyamines in testicular maturation and spermatogenesis, the activity of two enzymes involved in the polyamine synthetic pathway, L-ornithine decarboxylase (ODC) a...
The influence of different modes of FSH stimulation and cycloheximide on transferrin secretion by rat Sertoli cells was investigated using a superfusion culture system. Sertoli cells from 18-day-old...
The proliferation and differentiation of possible Leydig cell precursors in adult rats were studied after destruction of the existing Leydig cells with EDS or after daily treatment with hCG. After 2...
The activity of a nongonadotropic factor present in rat testicular interstitial fluid and capable of stimulating Leydig cell testosterone production was measured at intervals for 8 weeks after exp...
Active immunization of Ile-de-France rams against estradiol (E2) resulted in the production of E2-neutralizing antibodies and an elevation in the plasma concentrations of FSH, LH, and testosterone...
Cytosol and nuclear receptor concentrations in Sertoli cells isolated from the testes of 15-, 25-, and 35-day-old rats were measured using hydroxylapatite separation procedures. In these cells the m...
The numbers of Ap and Ad spermatogonia per unit section of the testis were calculated in autopsy specimens from young adults and elderly men without testicular pathology. The number of Ap spermatogo...
The transferrin-mediated transcellular transport of 59Fe across confluent epithelial sheets of Sertoli cells grown on Millipore filters was investigated. These filters had been impregnated with reco...
