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

open access: yesAdvanced 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 ...

The role of PLAU in polycystic ovary syndrome: activation of STAT3-mediated NLRP3 signaling to promote granulosa cell injury, inflammation, and apoptosis

open access: yesApplied Biological Chemistry
Background Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic disorder. Granulosa cell dysfunction is an important factor causing PCOS.PLAU has been shown to be upregulated in granulosa cells of PCOS patients, but its potential ...

Large-scale DNA demethylation occurs in proliferating ovarian granulosa cells during mouse follicular development

open access: yesCommunications Biology, 2021
Tomoko Kawai et al. investigate DNA methylation patterns during granulosa cell differentiation and proliferation. Their results suggest that sequential epigenetic events are essential for progressive changes in granulosa cell differentiation.

Modification of the Transcription Factor FOXL2 at Serines 101 and 107 Disables DNA Binding, Leads to Nucleolar Relocalization, and Rewires Granulosa-Cell Programs. [PDF]

open access: yesFASEB J
PKC‐mediated phosphorylation of FOXL2 weakens DNA binding, alters subnuclear localization and protein interactions, and reshapes FOXL2‐dependent transcriptional programs in granulosa cells, supporting a reversible mechanism that modulates FOXL2 activity through phosphorylation of its DNA‐binding domain. ABSTRACT FOXL2 is a forkhead transcription factor

Functional Sex Reversal in Adult Gonochoristic Teleosts is Mediated by Ovarian Germline Stem Cell Plasticity and Somatic Cell Transdifferentiation

open access: yesAdvanced Science, EarlyView.
Oocytes play crucial roles in maintaining ovarian fate in adult gonochoristic fish. Targeted oocyte ablation with aromatase inhibition triggers the activation of surviving germline stem cells and the transdifferentiation of somatic cells from granoulosa/theca to Sertoli/Leydig lineages, inducing a complete and functional female‐to‐male sex reversal ...

Downregulating lncRNA NEAT1 induces proliferation and represses apoptosis of ovarian granulosa cells in polycystic ovary syndrome via microRNA-381/IGF1 axis

open access: yesJournal of Biomedical Science, 2021
Objective Researchers have revealed the combined functions of long noncoding RNAs (lncRNAs) and microRNA (miRNAs) in polycystic ovary syndrome (PCOS). This study aimed to understand the role of nuclear-enriched abundant transcript 1 (NEAT1) and miR-381 ...

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

open access: yesAnimal 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.

Homeobox A7 increases cell proliferation by up-regulation of epidermal growth factor receptor expression in human granulosa cells

open access: yesReproductive Biology and Endocrinology, 2010
Background Homeobox (HOX) genes encode transcription factors, which regulate cell proliferation, differentiation, adhesion, and migration. The deregulation of HOX genes is frequently associated with human reproductive system disorders. However, knowledge
