Alterations in chromosomal synapses and DNA repair in apoptotic spermatocytes of Mus m. domesticus [PDF]
We investigated whether apoptotic spermatocytes from the mouse Mus m. domesticus presented alterations in chromosomal synapses and DNA repair. To enrich for apoptotic spermatocytes, the scrotum’s temperature was raised by partially exposing animals for ...

TDRD6 mediates early steps of spliceosome maturation in primary spermatocytes. [PDF]
Tudor containing protein 6 (TDRD6) is a male germ line-specific protein essential for chromatoid body (ChB) structure, elongated spermatid development and male fertility.

WFS1 Deficiency Impairs PIAS4-Associated SUMOylation and Increases Ubiquitin-Mediated Spermatogenesis-Related Protein Degradation Leading to Testicular Male Infertility. [PDF]
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.

BOULE is Essential for the Dynamic Disassembly of Heat Shock Granules in Male Germ Cells. [PDF]
BOULE orchestrates stress granule disassembly in germ cells via a two‐pronged mechanism: it promotes G3BP1 ubiquitination by upregulating TRIM27, generating a signal for VCP/FAF2 recruitment, and it maintains G3BP1 and FAF2 protein levels. BOULE deficiency disrupts disassembly complex formation, leading to impaired heat shock granule clearance ...

Spermatocytic tumor (ST) is a very rare disease, accounting for approximately 1% of testicular cancers. Previously classified as spermatocytic seminoma, it is currently classified within the non-germ neoplasia in-situ-derived tumors and has different clinical-pathologic features when compared with other forms of germ cell tumors (GCTs).

Abstract Spermatocytic seminoma is a rare germ cell tumor distinct from classical seminoma, both clinically and pathologically. It affects older men, has not been associated with a history of cryptorchidism, and has no known counterpart in ovary or any other site.

Chromosome movements in locust spermatocytes [PDF]
We tested whether the mechanisms of chromosome movement during anaphase in locust [Locusta migratoria (L.)] spermatocytes might be similar to those described in crane-fly spermatocytes. Actin and myosin have been implicated in anaphase

Igsf11 deficient mouse spermatocytes develop beyond pachytene checkpoint.
(A) Comparison of the axial element assembly in spermatocytes of the control (Igsf11+/-) and mutant (Igsf11-/-) mice using SYCP3 and REC8 as markers. (B) Meiotic progression analysis of the first wave spermatocytes with the VPHS transgenic reporter.

WNK1 is required during male pachynema to sustain fertility
Summary: WNK1 is an important regulator in many physiological functions, yet its role in male reproduction is unexplored. In the male germline, WNK1 is upregulated in preleptotene spermatocytes indicating possible function(s) in spermatogenic meiosis ...

Cohesin SMC1β promotes closed chromatin and controls TERRA expression at spermatocyte telomeres
Cohesin SMC1β; ensures silencing at chromosome ends, restricts TERRA expression and RNA-DNA hybrid formation, and prevents telomer damage. Previous data showed that meiotic cohesin SMC1β protects spermatocyte telomeres from damage. The underlying reason,
