PSMA8‐Containing 20S Proteasome Regulates Spermiogenesis and Male Fertility
PSMA8 assembles s20S proteasome that degrades specific substrates in elongating spermatids. Degradation of s20S‐substrates activates translation of FXR1‐target mRNAs, which are essential for mitochondrial sheath formation and sperm morphogenesis.

Epi-mutations for spermatogenic defects by maternal exposure to di(2-ethylhexyl) phthalate
Exposure to environmental factors during fetal development may lead to epigenomic modifications in fetal germ cells, altering gene expression and promoting diseases in successive generations.

The Landscape and Regulation of Histone Crotonylation in Mammalian Gametes and Early Embryos
Histone crotonylation undergoes a genome‐wide transition from broad domains to canonical narrow peaks during minor zygotic genome activation (ZGA). This remodeling is required for proper major ZGA and blastocyst formation. Disruption of this transition by transcriptional inhibition, metabolic perturbation, or HDAC1 dysfunction impairs embryonic ...

Application of testicular organ culture system for the evaluation of spermatogenesis impairment
Recently, it was reported that a testicular organ culture system (TOCS) using polydimethylsiloxane (PDMS) chips with excellent oxygen permeability and biocompatibility, called the PDMS-chip ceiling (PC) method, enables improved spermatogenesis efficiency.

SRSF2 is required for mRNA splicing during spermatogenesis
Background RNA splicing plays significant roles in fundamental biological activities. However, our knowledge about the roles of alternative splicing and underlying mechanisms during spermatogenesis is limited. Results Here, we report that Serine/arginine-

Effects of dioxins on animal spermatogenesis: A state-of-the-art review
The male reproductive system is especially affected by dioxins, a group of persistent environmental pollutants, resulting in irreversible abnormalities including effects on sexual function and fertility in adult males and possibly on the development of ...

The study elucidates that paternal preconception stress can drive offspring hyperresponsivity of the stress system via hypomethylation of a specific DNA region in sperm. This key link is confirmed in a cohort of prospective fathers: the epigenetic alteration is associated with elevated stress hormone levels.

Evaluation of mRNA Contents of YBX2 and JHDM2A Genes on Testicular Tissues of Azoospermic Men with Different Classes of Spermatogenesis [PDF]
Objective: Animal model studies have shown that MSY2 and JHDM2A genes have an important role in spermatogenesis process and fertility of male mice. But the potential role of these genes in human spermatogenesis and fertility is not known yet. Therefore,

Actin-binding protein drebrin E is involved in junction dynamics during spermatogenesis
The actin-based cytoskeleton plays a critical role in the seminiferous epithelium during spermatogenesis by conferring cell shape, adhesion, structural support and cell polarity to both Sertoli and developing germ cells, which are essential for ...

P3FI–90 treatment targets KDM3B, reshapes the epigenetic landscape, and suppresses SHP1 expression, thereby activating STING–TBK1–IRF3–type I IFN signaling pathway. Consequently, CD8+ T cells are recruited to the tumor site and activated to produce IFN–γ and GZMB, leading to the killing of TNBC cells.
