Microsatellite instability and defects in mismatch repair proteins: a new aetiology for Sertoli cell‐only syndrome [PDF]

, 2017
Microsatellite instability is characteristic of certain types of cancer, and is present in rodents lacking specific DNA mismatch repair proteins. These azoospermic mice exhibit spermatogenic defects similar to some human testicular failure patients ...

Phthalate Exposure During Pregnancy and Lactation Transgenerationally Impairs the Epididymis in the Offspring of Rats

Journal of Biochemical and Molecular Toxicology, Volume 39, Issue 7, July 2025.
This study reveals that phthalate exposure induces tissue remodeling and alters gene expression in the epididymis of Sprague‐Dawley rats across two generations. The findings underscore the transgenerational impact of phthalates, highlighting their influence on oxidative stress and inflammatory pathways during critical developmental windows.

Therapeutic Effects of Naringin on Bisphenol A‐Induced Oxidative Stress Damage in Nervous and Reproductive Systems of Cockerel Chickens

Veterinary Medicine and Science, Volume 11, Issue 4, July 2025.
ABSTRACT Background Bisphenol A (BPA) is an endocrine‐disrupting chemical, and it is mostly used in plastic industries. Naringin is a potent flavonoid that has been reported to possess several beneficial pharmacological properties such as antioxidant, anti‐inflammatory, and antiapoptotic properties.

CRISPR/Cas9‐mediated genome editing reveals seven testis‐enriched transmembrane glycoproteins dispensable for male fertility in mice

Andrology, Volume 13, Issue 5, Page 1251-1260, July 2025.
Abstract Background Mammalian fertilization is mediated by multiple sperm acrosomal proteins, many of which are testis‐enriched transmembrane glycoproteins expressed during spermiogenesis (e.g., Izumo sperm‐egg fusion 1, Sperm acrosome associated 6, and Transmembrane protein 95).
