Polystyrene microplastics impaired the function of leydig cells via GRP78/PERK/CHOP mediated endoplasmic reticulum stress in vivo and in vitro

open access: yesEcotoxicology and Environmental Safety
The toxic effect of Polystyrene Microplastics (PS-MPs) on leydig cells were found in male mice, but the toxic mechanism was not clear. The PS-MPs exposure mice model and cell model were established in this study to explore the leydig cells toxic ...

Androgens Modulate Tumor–Immune Interactions in Testicular Germ Cell Tumors

open access: yesAndrology, EarlyView.
ABSTRACT Background The majority of testicular germ cell tumors (TGCT) are derived from the germ cell neoplasia in situ and arise after puberty in the local presence of high levels of testosterone. The seminoma subtype features a rich inflammatory infiltrate which impacts tumor progression but the role of testosterone in shaping tumor–immune ...

Gene Expression During Development of Fetal and Adult Leydig Cells

open access: yes, 2007
In rats and mice, Leydig cells are formed as two morphologically and functionally different generations. The first generation develops in utero, from undifferentiated stem Leydig cells (SLCs) that differentiate into fetal Leydig cells (FLCs). After birth,

Pubertal Dynamics of Sertoli and Leydig Cell Dysfunction in Klinefelter Syndrome

open access: yesClinical Endocrinology, EarlyView.
ABSTRACT Context Klinefelter syndrome (KS), defined by a 47, XXY karyotype, is commonly associated with progressive testicular failure. The precise timing of Sertoli and Leydig cell dysfunction during puberty remains unclear. Objective To determine the onset and progression of testicular insufficiency during puberty in KS, and to assess whether ...

Current Approaches to Support Patients to Withdraw From Image and Performance Enhancing Drugs

open access: yesClinical Endocrinology, EarlyView.
ABSTRACT Image and performance‐enhancing drugs (IPEDs) include agents such as androgens, growth hormone, and erythropoietin, which are used to enhance appearance and physical performance. Androgens, also known as anabolic‐androgenic steroids (AAS), are the most used IPEDs worldwide.

High Uric Acid Promotes Stem Leydig Cell Senescence by CCDC90B Mediates Mitochondrial Quality Control Imbalance

open access: yesCell Proliferation, EarlyView.
In hyperuricemia, uric acid inhibits CCDC90B ubiquitination degradation by binding to it. Excessive CCDC90B induces mitochondrial calcium overload, leading to mitochondrial quality control imbalance and ultimately resulting in SLC senescence and decreased testosterone levels.

A Noncanonical Protein Degradation Pathway That Regulates Germ Cell Maintenance

open access: yesCell Proliferation, EarlyView.
SENP8 regulates a non‐canonical NEDD8‐dependent pathway to stabilize STAT1, promote CCL2/CCL5 transcription, and maintain germ cell proliferation and migration.

Testicular torsion in foals and stallions

open access: yesEquine Veterinary Education, EarlyView.
Summary Testicular torsion is a rare condition in horses characterised by a change in the position of the testis due to the testicular mesentery twisting around its own axis; it can occur both when the testis is still in the abdominal cavity and when it has descended into the scrotum.
