WFS1 Deficiency Impairs PIAS4‐Associated SUMOylation and Increases Ubiquitin‐Mediated Spermatogenesis‐Related Protein Degradation Leading to Testicular Male Infertility

Advanced Science, EarlyView.
The findings establish a critical role for WFS1 in human male fertility. Mechanistically, WFS1 interacts with PIAS4 to promote the SUMOylation of key spermatogenesis‐associated proteins, which in turn competitively inhibits their K48‐linked ubiquitin‐mediated degradation during spermatogenesis.

Prevention of Early Onset of Breast Cancer With Ashwagandha

Molecular Carcinogenesis, EarlyView.
ABSTRACT Prevention of breast cancer is feasible because many risk factors for this malignancy are known (e.g., family history, reproductive factors, etc.). Medicinal plants and/or their bioactive phytochemicals are attractive for the prevention of early onset of breast cancer due to their generally favorable safety profile.

Incretin‐Based Therapies: A Testable Hypothesis Linking Incretin Signaling, Mitochondrial Redox, and OXPHOS Efficiency

Obesity, EarlyView.
ABSTRACT Objective Incretin‐based obesity therapies (IBTs), especially GLP‐1 receptor agonists (GLP‐1 RAs), effectively treat obesity and improve comorbidities. However, their impact on energy metabolism is unclear. A recent case of acute generalized muscle weakness in a patient with mitochondrial myopathy after tirzepatide exposure raises concerns ...

Contact Activation Is Alleviated by Testosterone Replacement Therapy in Klinefelter Syndrome: Evidence of Hormonal and Metabolic Modulation

Andrology, EarlyView.
ABSTRACT Background Klinefelter syndrome is associated with a markedly increased risk of venous thrombosis. While hypogonadism and metabolic dysfunction are known contributors, the role of the contact activation system in Klinefelter syndrome remains unexplored.

Mesenchymal Stem Cells From a Klinefelter Syndrome Patient: Functional Characterization and Therapeutic Implications

Andrology, EarlyView.
ABSTRACT Background Cell therapy, particularly those utilizing mesenchymal stem/stromal cells (MSCs), is gaining traction as a therapeutic option for regenerative treatment in patients with limited therapeutic options. Although the safety of MSC‐based interventions is well established, uncertainties remain regarding how genetic abnormalities and ...

Assessing a Model for a Complex Systemic Disorder—The Value of Male Mice With a Supernumerary X Chromosome for Klinefelter Syndrome Research

Andrology, EarlyView.
ABSTRACT Introduction Direct experimental investigation of Klinefelter syndrome (KS) in patients is limited because the syndrome manifests heterogeneously and affects multiple organ systems. Studying KS therefore requires a model that captures this complexity as accurately as possible while still permitting controlled experimental manipulation ...
