The essential roles of M ps 1 in spermatogenesis and fertility in mice

Cell Death and Disease, 2021
Monopolar spindle 1 (MPS1), which plays a critical role in somatic mitosis, has also been revealed to be essential for meiosis I in oocytes. Spermatogenesis is an important process involving successive mitosis and meiosis, but the function of MPS1 in ...

Hormonal control and signaling of the testis of the bat Molossus molossus during the processes of testicular maturation, regression, and recrudescence

The Anatomical Record, EarlyView.
Abstract Molossus molossus, a species of neotropical bat belonging to the Molossidae family, has an annual reproductive cycle that includes two peaks of spermatogenic activity, one in April and another in September, and a period of total testicular regression in December.

ASRGL1 is highly expressed specifically in spermatocytes of older mice.

, 2019
Spermatocyte marker SYCP3 (red) and ASRGL1 (green) were stained in 5μm testis tissue sections from mice ages PND13, PND22, and adult. ASRGL1 protein expression increases in SYCP3+ spermatocytes with age.

Cytofluorometric analysis of spermatocytic seminoma [PDF]

Cancer, 1993
Whether spermatocytic seminoma (SS) develops during meiosis or not is still controversial. To determine that, the DNA content of large, small, and intermediate cells of SS was measured by cytofluorometry to obtain DNA histograms for each cell type. The large cells were aneuploid and showed cell cycles with G0/G1 DNA values from 3C to 18C. The ploidy of

Ursolic Acid Alleviates Orchitis via Modulating Ferroptosis in Peritubular Myoid Cells of Testis

Animal Research and One Health, EarlyView.
Ursolic acid modulates key ferroptosis‐related pathways in the peritubular myoid cells of the testis in forest musk deer. ABSTRACT Chronic stress adversely affects reproductive health, increasing susceptibility to pathologies such as orchitis. Additionally, the maintenance of iron homeostasis is essential for preserving the function of the testicles ...

Lycium barbarum Polysaccharide Improves Iron Homeostasis in Spermatocytes and Sertoli Cells via NRF2 to Alleviate DEHP-Induced Male Reproductive Toxicity in Mice

Toxics
Male infertility, as a globally significant reproductive health issue, remains idiopathic in over 40% of cases. Reproductive disorders in males induced by environmental pollutants, such as di(2-ethylhexyl) phthalate (DEHP), have garnered considerable ...

Prion‐Like Protein LENG8‐Mediated Nucleation Drives Stress Granule Assembly [PDF]

Advanced science
LENG8 is a newly identified stress granule (SG) nucleator required for SG assembly. Following stress, nuclear LENG8 granules disassemble, allowing LENG8 to translocate into the cytoplasm and form independent nucleation foci. These foci fuse with canonical early G3BP1/TIA1 seeds via LENG8‐TIA1 binding to drive SG maturation.
