SDF‐1 Attenuates Oocyte Quality Decline During Reproductive Aging Through Autophagy‐Enhanced Stress Granule Scavenging

Advanced Science, EarlyView.
SDF‐1 levels decline significantly with maternal aging. Exogenous supplementation restores meiotic spindle morphology, chromosomal alignment, and mitochondrial function while reducing oxidative stress in aged oocytes. Mechanistically, SDF‐1 enhances autophagic activity to clear accumulated stress granules, thereby rescuing fertilization competence and ...

Dietary Glutamine Supplementation Alleviated Rumen Epithelium Oxidative Damage and Apoptosis Induced by Feed Restriction via Maintaining Mitochondrial Homeostasis in Female Yaks

Animal Research and One Health, EarlyView.
Dietary glutamine (Gln) supplementation increased the ATP levels and promoted cell proliferation in the rumen epithelium of feed‐restricted yaks. Besides, Gln inhibited ROS accumulation and reduced oxidative damage and apoptosis in the rumen epithelium of feed‐restricted yaks.

Lipopolysaccharide alters CEBPβ signaling and reduces estradiol production in bovine granulosa cells

CABI Agriculture and Bioscience, 2022
Background Bacterial infection of the uterus in postpartum dairy cows limits ovarian follicle growth, reduces blood estradiol concentrations, and leads to accumulation of bacterial lipopolysaccharide (LPS) in ovarian follicular fluid.

Genomic Structural Variations Provide Insights Into Litter Size and Teat Number Traits in Hu Sheep

Animal Research and One Health, EarlyView.
Here, we conducted whole genome sequencing on 300 Hu sheep with an average depth of 16.51X. Two candidate genes associated with litter size and teat number traits were identified, namely MAST2 and AFDN. ABSTRACT Litter size and the teat number are important economic indicators in sheep production.

Extraovarian Granulosa Cell Tumor

Yonsei Medical Journal, 2001
A 54-year-old woman was admitted to our hospital complaining of postcoital bleeding. Sonography of the abdomen showed a 8.2 x 8.9 cm-sized solid heterogeneous mass occupying the cul-de-sac, which appeared to be in no way connected with the ovary. On exploratory laparotomy, the tumor mass protruded from the posterolateral retroperitoneum of the pelvic ...

Overexpression of CDC25C affects the cell cycle of ovarian granulosa cells from adult and young goats

Electronic Journal of Biotechnology, 2018
Background: CDC25 is a dual-specificity phosphatase that was first identified in the yeast Schizosaccharomyces pombe as a cell cycle-defective mutant. Although CDC25 is involved in the cell cycle of ovarian granulosa cells, the CDC25 signaling pathway ...

Follicle Stimulating Hormone in Cattle Breeding: Fundamentals, Innovations, and Scope

Animal Research and One Health, EarlyView.
FSH is crucial in cattle reproduction, with exogenous administration enhancing breeding and embryo production. Recombinant FSH offers advantages over pituitary‐extracted variants, including fewer injections, reduced stress, and safer production. These innovations improve breeding efficiency, optimize reproductive outcomes, and contribute to sustainable
