Recombinant Antibodies Inhibit Enzymatic Activity of the E3 Ubiquitin Ligase CHIP via Multiple Mechanisms.

Carboxyl-terminus of Hsp70-Interacting Protein (CHIP) is an E3 ubiquitin ligase that marks misfolded substrates for degradation. Hyper-activation of CHIP has been implicated in multiple diseases, including cystic fibrosis and cancer, suggesting that it may be a potential drug target. However, there are few tools available for exploring this possibility.

Association Between Type 2 Diabetes and Hypogonadism in India: An Observational Study.

Introduction: Hypogonadism is a common comorbidity associated with several metabolic disorders including type 2 diabetes (T2D) that can remain undetected without proper screening. Here, we evaluated the prevalence of hypogonadism in Indian male patients with T2D with or without obesity.

Methods: In this prospective, observational study, male patients with T2D and hypogonadism were evaluated symptomatically using the androgen deficiency in ageing male (ADAM) questionnaire at baseline and confirmed on the basis of total testosterone (TT) levels (<300 ng/dL) at Days 5-7 (Visit 2) and 9-14 (Visit 4) assessed after 12 hours of fasting between 8 AM and 10 AM.

Age, sex, and mitochondrial-haplotype influence gut microbiome composition and metabolites in a genetically diverse rat model.

We evaluated the impact of sex and mitochondrial-haplotype on the age-related changes in the fecal gut microbiome of the genetically heterogeneous rodent model, the OKC-HET rat. Alpha-diversity, measuring richness and evenness of gut microbiome composition, did not change with age or mitochondrial-haplotype. However, beta-diversity, a measure of microbial differences among samples, was significantly modulated by age in male and female rats in both mitochondrial-haplotypes.

Selenium ameliorates oxidized phospholipid-mediated testicular dysfunction and epididymal sperm abnormalities following Bisphenol A exposure in adult Wistar rats.

Bisphenol A (BPA) is an endocrine-disrupting compound extensively utilized in the production of polycarbonate polymers and epoxy resins that, upon exposure, pose a significant threat to male reproductive health because of its estrogenic properties. Accumulating evidence suggests that BPA exposure disrupts the normal process of spermatogenesis, alters testicular morphology and function, and interferes with testicular steroidogenesis and hormonal signaling. However, the precise mechanism by which BPA affects testicular function remains unclear.
