Evidence that undernutrition increases AgRP signaling to arcuate kisspeptin neurons in male and female lambs
Proper energy balance is important for reproductive success, but the central mechanism whereby undernutrition inhibits reproduction remains to be fully elucidated. Given that arcuate (ARC) kisspeptin (Kiss1) neurons express melanocortin ...

Timing and duration of alpha-minimum essential medium exposure during preimplantation development determine long-term metabolic phenotypes in mice
The environment experienced during preimplantation development can influence long-term health. Continuous culture of mouse preimplantation embryos in α-minimum essential medium (αMEM) for 48 h induces the established “MEM mouse” phenotyp...

Effects of intravaginal infusion of the osteopontin peptide possessing integrin-binding motifs on an inflammation-like response in the endometrium of dairy cows
Intravaginal infusion of a peptide possessing the integrin-binding motifs of osteopontin (OPN peptide), a seminal protein, restored fertility in dairy cows by restoring the endometrial epidermal growth factor profile. Hypothetically, thi...

Heat stress during maternal recognition of pregnancy alters cortisol concentrations and fertility in Holstein cows
Heat stress has a strong negative impact on reproduction in dairy cattle during summer. However, the effects of exposure to heat stress and their relationship with cortisol during maternal recognition of pregnancy have not been fully cha...

Increasing global chromatin accessibility alone is insufficient to enhance global transcription during mouse zygotic gene activation
In mice, zygotic gene activation (ZGA) occurs in two waves: a minor wave at the 1-cell stage and a major wave at the 2-cell stage. At the 1-cell stage, chromatin is highly decondensed and transcriptionally permissive; however, global tra...

Feasibility of preimplantation genomic selection using in vitro-produced embryos in Japanese Black cattle
Preimplantation genomic selection (PGS) using single nucleotide polymorphism (SNP) genotyping can be used to accelerate genetic improvement in cattle, but the technical components for in vitro-produced (IVP) embryos remain unvalidated in...

Seasonal reproductive and metabolic changes in male Pacific white-sided dolphins (Aethalodelphis obliquidens)
Seasonal reproductive dynamics were investigated in two adult male Pacific white-sided dolphins (Aethalodelphis obliquidens, formerly Lagenorhynchus obliquidens) maintained at the Enoshima Aquarium over a two-year period (December 2018–N...

Proteomic profiling of sperm with differential freezability in Wannan Black pig
Sperm freezability varies considerably among pigs owing to genetic, husbandry, and management differences. Boar sperm cryopreservation remains underutilized owing to its inconsistent freezability. Semen with good freezability (GF) increa...

LRRC37A is an acrosomal protein required for acrosome integrity and sperm head morphogenesis
Fertilization depends on the proper formation and function of the acrosome, a specialized organelle essential for sperm-oocyte interaction. Defects in acrosome biogenesis impair fertilization and cause severe male infertility, including ...

Distinct localization and potential functions of GPR37 signaling mediated by prosaposin and protectin D1 in the rat pituitary gland
Prosaposin (PSAP), a secreted glycoprotein with neurotrophic activity, and protectin D1, a docosahexaenoic acid-derived lipid mediator, are endogenous ligands of G protein-coupled receptor 37 (GPR37). Although PSAP is expressed in the pi...
