Can Hormonal Therapy Improve the Outcomes of mTESE in Patients With Non‐Obstructive Azoospermia?

Andrology, EarlyView.
ABSTRACT Background Non‐obstructive azoospermia (NOA) represents the most severe form of male infertility. Hypogonadism is common in NOA patients, and normal testosterone (T) levels are considered essential for spermatogenesis. Fertility‐preserving hormonal therapy (FpHT) has been proposed to optimize hormonal milieu and improve sperm retrieval rates ...

Adenosine—A Regulator of Human Testicular Peritubular Cells

Andrology, EarlyView.
ABSTRACT Background Extracellular purines, in particular ATP and adenosine, are regulators of physiological and pathophysiological processes throughout the human body. Roles in the human testis are emerging and include actions on peritubular cells, which form the wall of seminiferous tubules.

Obesity Is an Independent Risk Factor for Oligozoospermia, With Co‐Existing Hyperglycemia Exacerbating Risks of Asthenozoospermia and Elevated Sperm DNA Fragmentation

Andrology, EarlyView.
ABSTRACT Background Metabolic health plays a critical role in maintaining male fertility and may influence offspring health. Therefore, it is necessary to incorporate metabolic indicators into the clinical assessment of male fertility. However, the relationships between different metabolic abnormalities and semen quality remain incompletely understood.

The dynamic expression of YAP is essential for the development of male germ cells derived from human embryonic stem cells

Scientific Reports
YAP plays a vital role in controlling growth and differentiation in various cell lineages. Although the expression of YAP in mice testicular and spermatogenic cells suggests its role in mammalian spermatogenesis, the role of YAP in the development of ...

Targeting Egfr‐Mediated Cell Proliferation and Lipid Metabolism Separation Effectively Accelerate Liver Regeneration

Cell Proliferation, EarlyView.
AREG coordinates cell proliferation and lipid metabolism reprogramming during liver regeneration and targeting lipid metabolism can promote liver regeneration. ABSTRACT Hepatocyte proliferation restores liver mass after partial hepatectomy (PHx), but the metabolic cost of this process remains unclear.

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

Cell 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

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

New Insights into D-Aspartate Signaling in Testicular Activity

Cells
D-aspartate (D-Asp) is an amino acid found in high concentrations in the testis and pituitary gland. Increasing evidence suggests that D-Asp promotes spermatogenesis by activating testosterone production in the Leydig cells via LH release from the ...

Stimulating proteasomal degradation in human proteinopathies

The FEBS Journal, EarlyView.
The proteasome mediates the degradation of a wide range of proteins. Boosting proteasomal degradation may be beneficial in several disease contexts and can be achieved either by modulating proteasome activity or by improving substrate delivery. Proteasome activity can be enhanced by increasing proteasome abundance, inducing constitutive gate opening ...
