TSPO: kaleidoscopic 18-kDa amid biochemical pharmacology, control and targeting of mitochondria [PDF]

open access: yes, 2016
The 18-kDa translocator protein (TSPO) localizes in the outer mitochondrial membrane (OMM) of cells and is readily up-regulated under various pathological conditions such as cancer, inflammation, mechanical lesions and neurological diseases. Able to bind

Cadmium-induced apoptosis of Leydig cells is mediated by excessive mitochondrial fission and inhibition of mitophagy

open access: yesCell Death and Disease, 2022
Cadmium is one of the environmental and occupational pollutants and its potential adverse effects on human health have given rise to substantial concern. Cadmium causes damage to the male reproductive system via induction of germ-cell apoptosis; however,

Sertoli Cell‐Derived Extracellular Vesicles Orchestrate Cadmium‐Induced Testicular Inflammation and Fibrosis

open access: yesAdvanced Science, EarlyView.
Environmental cadmium exposure disrupts testicular homeostasis through a novel intercellular communication axis. Stressed Sertoli cells release extracellular vesicles carrying damage‐associated molecular patterns and mitochondrial fragments, which activate macrophages via TLR4/NF‐κB signaling.

Characterization of stem cells associated with seminiferous tubule of adult rat testis for their potential to form Leydig cells

open access: yesStem Cell Research, 2019
Adult testicular Leydig cells arise from stem cells in the neonatal and adult testis. The nature of these stem Leydig cells (SLCs) have not been well characterized.

An insight into metastatic Leydig cell tumors: A case report

open access: yesSAGE Open Medical Case Reports, 2023
Sex cord-stromal tumors comprise approximately 5% of all testicular tumors, while the remainder are of germ cell origin. Leydig cell tumors are the most common subtype of testicular sex cord-stromal tumors and account for 1%–2% of all testicular tumors ...

Thyroid hormone receptors and ligand, tissue distribution and sexual behavior [PDF]

open access: yes, 2018
The thyroid hormones (THs) triiodothyronine (T3) and tetraiodothyronine, or thyroxine (T4), not only dramatically impact on development and differentiation, but also on the sexual and reproductive function.

Steroidogenic Factor 1 Differentially Regulates Fetal and Adult Leydig Cell Development in Male Mice1

open access: yesBiology of Reproduction, 2015
The nuclear receptor steroidogenic factor 1 (SF-1, AD4BP, NR5A1) is a key regulator of the endocrine axes and is essential for adrenal and gonad development. Partial rescue of Nr5a1−/− mice with an SF-1-expressing transgene caused a hypomorphic phenotype

Determining the timeline of gonadal and genital differentiation in male and female equine fetuses allows for early detection and intervention in malformations

open access: yesThe Anatomical Record, EarlyView.
Abstract Sexual differentiation in the equine fetus involves coordinated morphogenetic processes that shape both the gonads and the genital ducts. Although the formation of testes and ovaries has been relatively well documented, the temporal dynamics and morphometric patterns of the mesonephric (Wolffian) and paramesonephric (Müllerian) ducts remain ...

RiboTag analysis of actively translated mRNAs in Sertoli and Leydig cells in vivo. [PDF]

open access: yesPLoS ONE, 2013
Male spermatogenesis is a complex biological process that is regulated by hormonal signals from the hypothalamus (GnRH), the pituitary gonadotropins (LH and FSH) and the testis (androgens, inhibin).

A prospective study on contrast-enhanced magnetic resonance imaging of testicular lesions: distinctive features of Leydig cell tumours [PDF]

open access: yes, 2015
OBJECTIVES: Up to 20 % of incidentally found testicular lesions are benign Leydig cell tumours (LCTs). This study evaluates the role of contrast-enhanced magnetic resonance imaging (MRI) in the identification of LCTs in a large prospective cohort study.
