LARP7 is required for sex chromosome silencing during meiosis in mice.

PLoS ONE
Meiotic sex chromosome inactivation (MSCI) is an essential event in meiotic progression in mammalian spermatogenesis. We found that La Ribonucleoprotein 7 (LARP7) is involved in MSCI. LARP7 plays a role in fetal germ cells to promote their proliferation,

RAD51 has overall reduced protein expression in first-wave spermatocytes from juvenile mice.

, 2019
Spermatocyte marker SYCP3 (red) and RAD51 (green) were stained in 5μm testis tissue sections from mice ages PND13, PND22, and adult. RAD51 protein expression increases in SYCP3+ spermatocytes with age.

The ubiquitin-conjugating enzyme HR6B is required for maintenance of X chromosome silencing in mouse spermatocytes and spermatids

BMC Genomics, 2010
Background The ubiquitin-conjugating enzyme HR6B is required for spermatogenesis in mouse. Loss of HR6B results in aberrant histone modification patterns on the trancriptionally silenced X and Y chromosomes (XY body) and on centromeric chromatin in ...

Anatomical and Histological Descriptions of the Male Reproductive System of the Alfalfa Weevil of Hypera postica (Gyllenhal, 1813) (Coleoptera: Curculionidae) Using Light and Scanning Electron Microscopies

Acta Zoologica, EarlyView.
ABSTRACT Features of the reproductive organs, such as the number of testicular follicles, testis colour and the morphology of the glands, can be used as systematic characters. For this purpose, this paper was the first description of the male reproductive system anatomy and histology of Hypera postica (Gyllenhal, 1813) (Coleoptera: Curculionidae), a ...

ATM has reduced protein expression in first-wave spermatocytes from juvenile mice.

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

GSK3α‐mediated regulation of the RNA demethylase fat mass and obesity‐associated protein (FTO) during murine spermatogenesis

The FEBS Journal, EarlyView.
FTO regulates mRNA stability and translational efficiency through its m6A‐demethylation activity. GSK3 functions as an upstream regulator of FTO, leading to its inhibition via phosphorylation. In male germ cells, FTO activity is kept in check by GSK3α.

Continuous darkness is associated with improved growth performance during a high‐temperature period and sex‐specific modulation of early gonadal development in juvenile yellowtail (Seriola quinqueradiata)

Journal of Fish Biology, EarlyView.
Abstract Selective breeding of yellowtail (Seriola quinqueradiata) is expanding in Japan, increasing the demand for practical reproductive control tools in commercial aquaculture to reduce genetic risks from escapees. Slowing early gonadal development through environmental manipulation may support future sterilization strategies, particularly when ...
