同济大学医学院附属同济医院 吴登龙教授 阐明 前列腺癌 治疗 研究成果 Molecular Cell
2020/10/28
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...
Development of transmembrane signaling in the fetal rat Leydig cell
transmembrane signaling fetal rat Leydig cell
2009/2/23
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...
Stimulation of the proliferation and differentiation of Leydig cell precursors after the destruction of existing Leydig cells with ethane dimethyl sulphonate(EDS)can take place in the absence of LH
proliferation differentiation Leydig cell precursors
2009/2/23
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 differential effects of the indazole-carboxylic acid derivative, tolnidamine, on Sertoli cell protein secretion
Indazole-carboxylic acids tolnidamine antispermatogenic agents Sertoli cell
2009/2/23
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...
Leydig cell and extracellular matrix effects on Sertoli cell function:biochemical and morphologic studies
Leydig cell extracellular matrix Sertoli cell function
2009/2/23

The action of calcitonin on the TM4 Sertoli cell line and on rat Sertoli cell-enriched cultures
TM4 Sertoli cell line rat Sertoli cell-enriched cultures
2009/2/23
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 ...
The actions of calcitonin on the TM3 Leydig cell line and on rat Leydig cell-enriched cultures
calcitonin TM3 Leydig cell line rat Leydig cell-enriched cultures
2009/2/23
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...
The changing profiles of L-ornithine decarboxylase and S-adenosyl-L-methionine decarboxylase activities in testicular cell types during sexual maturation of male rats
L-ornithine decarboxylase S-adenosyl-L-methionine testicular cell types
2009/2/23
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...
