Improvement of Testicular Steroidogenesis Using Flavonoids and Isoflavonoids for Prevention of Late-Onset Male Hypogonadism

open access: yesAntioxidants, 2020
Androgen production, being important for male fertility, is mainly accomplished by the Leydig cells from the interstitial compartment of the testis. Testosterone plays a critical role in testis development, normal masculinization, and the maintenance of ...

Novel machine learning models to predict endocrine disruption activity for high-throughput chemical screening

open access: yesFrontiers in Toxicology, 2022
An area of ongoing concern in toxicology and chemical risk assessment is endocrine disrupting chemicals (EDCs). However, thousands of legacy chemicals lack the toxicity testing required to assess their respective EDC potential, and this is where ...

Direct action through the Sertoli cells is essential for androgen stimulation of spermatogenesis [PDF]

open access: yes, 2010
Androgens act to stimulate spermatogenesis through androgen receptors (AR) on the Sertoli cells and peritubular myoid cells (PTM). Specific ablation of the AR in either cell type will cause a severe disruption of spermatogenesis.

Mouse CD52 is predominantly expressed in the cauda epididymis, regulated by androgen and lumicrine factors

open access: yesJournal of Human Reproductive Sciences, 2021
Background: Sperm maturation takes place through contact between sperm and proteins produced in the epididymal lumen. CD52 had been characterised in the sperm; however, the expression and its regulation in the epididymis are mostly unknown.

Bad expression influences time to androgen escape in prostate cancer [PDF]

open access: yes, 2007
<b>OBJECTIVE</b>: To assess the role of selected downstream Bcl-2 family members (Bad, Bax, Bcl-2 and Bcl-xL) in the development of androgen-independent prostate cancer (AIPC), as androgen-deprivation therapy is the treatment of choice in ...

Androgen receptor acetylation governs trans activation and MEKK1-induced apoptosis without affecting in vitro sumoylation and trans-repression function [PDF]

open access: yes, 2014
This work was supported by grants from the NIH (R01CA86072 to R.G.P. and R01CA72038-01 to S.A.W.F.) and The Susan Komen Breast Cancer Foundation (to R.G.P.). R.T.H. and E.J. were supported by the Medical Research Council. Y.-G.Y.

Testicular development in mice lacking receptors for follicle stimulating hormone and androgen [PDF]

open access: yes, 2012
Post-natal testicular development is dependent on gonadotrophin and androgen stimulation. Follicle stimulating hormone (FSH) acts through receptors (FSHR) on the Sertoli cell to stimulate spermatogenesis while androgens promote testis growth through ...

Gene amplifications associated with the development of hormone- resistant prostate cancer [PDF]

open access: yes, 2003
Purpose: Hormone resistance remains a significant clinical problem in prostate cancer with few therapeutic options. Research into mechanisms of hormone resistance is essential.

Effect of FSH on testicular morphology and spermatogenesis in gonadotrophin-deficient hypogonadal mice lacking androgen receptors [PDF]

open access: yes, 2010
Follicle stimulating hormone (FSH) and androgen act to stimulate and maintain spermatogenesis. FSH acts directly on the Sertoli cells to stimulate germ cell number and acts indirectly to increase androgen production by the Leydig cells.

Spermatogenesis and sertoli cell activity in mice lacking Sertoli cell receptors for follicle stimulating hormone and androgen [PDF]

open access: yes, 2008
Spermatogenesis in the adult male depends on the action of FSH and androgen. Ablation of either hormone has deleterious effects on Sertoli cell function and the progression of germ cells through spermatogenesis.
