T Cell Microenvironmental Impacts and Therapeutic Opportunities: Application to Human Testicular Germ Cell Tumors

Andrology, EarlyView.
ABSTRACT Testicular germ cell tumors (TGCT) are the leading malignancy in adolescent and young adult males, yet the immunological and cellular mechanisms governing their tumor microenvironment (TME) remain poorly understood. Here, we present a comprehensive review of TGCT pathobiology with a focus on the immune landscape, particularly the role of tumor‐

Anti-Müllerian hormone as a diagnostic marker for testicular degeneration in dogs: insights from cryptorchid models

Frontiers in Veterinary Science
IntroductionThe increasing prevalence of infertility in male dogs in clinical practice mirrors current trends seen in human medicine. Acquired infertility is notably more common in dogs compared to congenital causes, with conditions such as testicular ...

Histomorphometric study of testis in deltamethrin treated albino rats

Toxicology Reports, 2014
Deltamethrin, a type II synthetic pyrethroid, has lead to a widespread concern over the potential adverse effects on human health. Adult Wistar albino rats, weighing 150–200 g, were divided into two groups of ten animals each.

Testicular SIRT1 Loss Reveals an Aging‐Like Proteomic Landscape and Precipitates Reproductive Deterioration

Andrology, EarlyView.
ABSTRACT Background Advanced paternal age is associated with reduced male fertility and testicular dysfunction. Among the molecular regulators involved in aging, SIRT1, a NAD+‐dependent deacetylase, plays a pivotal role in maintaining oxidative balance and cellular homeostasis.

In Situ Expression of miR‐371a‐3p and miR‐373‐3p in Testicular Germ Cell Tumours and Detection in Serum

Andrology, EarlyView.
ABSTRACT Background Testicular germ cell tumours (TGCTs) are the most common type of tumour diagnosed in young men, and reliable non‐invasive biomarkers are crucial for clinical management. MicroRNAs (miRNAs) from the miR‐371–373 cluster have recently been identified as novel and more sensitive serum biomarkers than the conventional protein‐based ...

A TECHNIQUE FOR THE RADIOAUTOGRAPHY OF GERM CELLS IN WHOLE MOUNTS OF SEMINIFEROUS TUBULES [PDF]

, 1969
A technique has been described for preparing radioautographs of germ cells in intact segments of seminiferous tubules from rat testis. Pieces of tubules were dissected from testes, fixed in Bouin's fluid and stained in Harris hematoxylin.

Peroxiredoxin 4 Involved in Spermatogenesis by Affecting Oxidative Stress and Ferroptosis

Andrology, EarlyView.
ABSTRACT Background The main functions of testes are sperm production and androgen secretion in testicular befitting microenvironment. Excessive level of the reactive oxygen species (ROS) from metabolism and cellular events can lead to oxidative stress (OS) and ferroptosis, which injure the functions of mitochondria and endoplasmic reticulum (ER) of ...

STUDY OF INTRA TESTICULAR REGULATIONS OF SPERMATOGENESIS DIFFERENTIATION BY EX-VIVO APPROACH

Journal of Fundamental and Applied Sciences, 2015
The aim of this work is to study the regulation of intratesticular during spermatogenesis ex vivo. To highlight the progress of spermatogenesis ex vivo, we developed two cell culture systems of seminiferous tubules to study the role of local factors that
