Testis‐Enriched F‐Box Protein FBXO39 Is Important for Spermiogenesis and Male Fertility in Mice
ABSTRACT Background The SCF (Skp–Cullin–F‐box) complex is a major class of E3 ubiquitin ligases. F‐box proteins constitute the SCF complex and play a critical role in recognizing substrates for ubiquitination. In mice, several F‐box proteins, including FBXO36 and FBXO39, are predominantly expressed in testes.

ABSTRACT Background Retinoic acid plays a critical role in spermatogenesis during both spermatogonial differentiation and spermiation. Mice lacking enzymes that synthesize retinoic acid, Aldh1a1/1a2, in the testes are infertile. WIN 18,446 reversibly inhibits spermatogenesis by inhibiting ALDH1A1/1A2 and is a promising approach to male contraception ...

ABSTRACT Background Nonobstructive azoospermia (NOA) is the most severe form of male infertility, with genetic factors contributing to approximately 30% of cases. However, only a small fraction of all NOA cases can be explained by the current genetic findings.

EXOSC10, an essential nuclear RNA exosome‐associated 3′‐5′ exoribonuclease, is inhibited by the anticancer drug 5‐fluorouracil (5‐FU), and EXOSC10 depletion increases 5‐FU sensitivity. The colon‐cancer variant EXOSC10S402T, located in a proteolysis motif, is stable and nuclear but nonfunctional in vivo.

Serine Ameliorates Cadmium‐Induced Testicular Injury by Regulating the PGAM1/PHGDH Signaling Pathway
Serine mitigates cadmium‐induced testicular injury in mice by inhibiting the PGAM1/PHGDH pathway, restoring ion homeostasis and glycolysis, and relieving oxidative stress, inflammation, fibrosis, and apoptosis. ABSTRACT Cadmium (Cd) is a widespread environmental contaminant that impairs male reproductive function; however, the metabolic mechanisms ...

Chlorfenapyr reduces testicular weight, sperm quality, and reproductive hormones. This study highlights that RA within chitosan nanoparticles (RA‐CHNPs) are superior to Rosmarinic acid in mitigating CFP‐induced testicular damage. RA within chitosan nanoparticles leads to the reduction of NF‐κB and NLRP3 expression in seminiferous tubules and activates ...

Elevated LncRNA LINC00966 Suppresses PDE2A to Impair Sperm Motility in Asthenozoospermia
This study identifies LINC00966 as an upregulated lncRNA in asthenozoospermia associated with reduced sperm quality. Linc00966 suppresses Pde2a, disrupts cGMP signaling, and promotes oxidative stress, thereby impairing spermatogenic cell viability and migration.

ABSTRACT The RNA‐binding protein NANOS2 plays a crucial role in male gonocyte development and the maintenance of spermatogonial stem cells. In the absence of the Nanos2 gene (Nanos2‐KO), germ cells fail to enter G0 arrest and initiate the male differentiation program (including DNA methylation and the piRNA pathway), ultimately undergoing apoptosis ...

Deletion of Mgat2 in spermatogonia blocks spermatogenesis
Identifying factors required for spermatogenesis is important for understanding mechanisms of male fertility. Inactivation of either the Mgat1 or Man2a2 gene leads to a block in spermatogenesis causing infertility in male mice. MGAT1 GlcNAc-transferase initiates complex N-glycan synthesis and MAN2A2 mannosidase generates the substrate for MGAT2 GlcNAc ...
