Proline-rich tyrosine kinase 2 mediates gonadotropin-releasing hormone signaling to a specific extracellularly regulated kinase-sensitive transcriptional locus in the luteinizing hormone beta-subunit gene [PDF]

open access: yes, 2007
G protein-coupled receptor regulation of gene transcription primarily occurs through the phosphorylation of transcription factors by MAPKs. This requires transduction of an activating signal via scaffold proteins that can ultimately determine the outcome

Regulation of the G2/M Transition in Rodent Oocytes [PDF]

open access: yes, 2010
Regulation of maturation in meiotically competent mammalian oocytes is a complex process involving the carefully coordinated exchange of signals between the somatic and germ cell compartments of the ovarian follicle via paracrine and cell–cell coupling ...

Interspecific comparisons of anuran embryonic epidermal landscapes and energetic trade‐offs in response to changes in salinity

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Freshwater salinization is an emerging stressor in amphibian populations, and embryonic stages are most vulnerable. To better understand the variation in embryonic osmoregulation, we challenged embryos of two phylogenetically diverse anuran species, Xenopus laevis and Lithobates (Rana) sylvaticus, along a gradient of non‐lethal ...

Induction of final oocyte maturation in Cyprinidae fish by hypothalamic factors: a review

open access: yesVeterinární Medicína, 2009
Gonadotropin-releasing hormone in Cyprinidae as in other Vertebrates functions as a brain signal which stimulates the secretion of luteinizing hormone from the pituitary gland. Two forms of gonadotropin-releasing hormone have been identified in cyprinids,

Shared Lineage, Distinct Outcomes: Yap and Taz Loss Differentially Impact Schwann and Olfactory Ensheathing Cell Development Without Disrupting GnRH‐1 Migration

open access: yesGlia, EarlyView.
OECs, SCs, and Mel derive from SCPs. Sox10Cre;YapHet;TazKO mice show impaired SC maturation, reduced Mel formation, fewer SCPs, OECs, and olfactory neurons, but normal GnRH‐1 neuron migration. ABSTRACT Olfactory Ensheathing Cells (OECs) are glial cells originating from the neural crest and are critical for bundling olfactory axons to the brain.

The mitochondrial DNA copy number and ovary‐related reproductive disorders: A bidirectional two‐sample Mendelian randomization study

open access: yesInternational Journal of Gynecology &Obstetrics, Volume 169, Issue 1, Page 112-120, April 2025.
Abstract Objective In the present study, a bidirectional two‐sample Mendelian randomization approach was utilized to explore potential causal relationships between mitochondrial DNA copy number (mtDNA‐CN) and ovary‐related reproductive disorders (ORRDs), including ovarian dysfunction, ovarian cyst, polycystic ovary syndrome (PCOS), premature ovarian ...
