M-phase promoting factor (MPF) and mitogen activated protein kinases (MAPK) activities of domestic cat oocytes matured in vitro and in vivo [PDF]
, 2004 This work was undertaken in order to examine M-phase promoting factor (MPF) and mitogen-activated protein kinases (MAPK) activities during meiotic progression of cat oocytes cultured in two different media for two different incubation times and ...

A Requirement for Fatty Acid Oxidation in the Hormone-Induced Meiotic Maturation of Mouse Oocytes [PDF]
, 2013 We have previously shown that fatty acid oxidation (FAO) is required for AMP-activated protein kinase (PRKA)-induced maturation in vitro. In the present study, we have further investigated the role of this metabolic pathway in hormone-induced meiotic ...

Advanced Science, EarlyView.ACLY is vital for early embryo development. IGF‐1 activates AKT to phosphorylate ACLY, driving its nuclear localization and recruitment of HATs (P300/HAT1), boosting acetyl‐CoA production and histone acetylation for transcriptional activation. Conversely, ACLY deficiency (via knockdown, knockout, or AKT inhibition) reduces nuclear acetyl‐CoA, disrupts ...

Expression and regulation of estrogen receptor 2 and its coregulators in mouse granulosa cells
The Journal of Reproduction and Development, 2022 The cooperative effects of estrogen and oocyte-derived paracrine factors (ODPFs) play critical roles in the normal development of ovarian follicles; however, the mechanism underlying this cooperation has not been well studied.

Gentle Label‐Free Nonlinear Optical Imaging Relaxes Linear‐Absorption‐Mediated Triplet
Advanced Science, EarlyView.The phototoxicity in nonlinear optical microscopy arises mainly from linear absorption of intrinsic biomolecules rather than nonlinear absorption. This mechanism is supported by a reproducible phototoxicity assay based on widely available chicken breast.

Atmospheric pollutants and their impact on murine and human reproduction
Actualidades Biológicas, 2022 Atmospheric pollution is caused by the presence or combination of physical, chemical, or biological pollutants in the air. In recent years, the most studied pollutant is particulate matter (PM), a varied mixture of solid and liquid particles.

Evidence for a Functional Interaction between Integrins and G Protein-activated Inward Rectifier K+ Channels [PDF]
, 1998 Heteromultimeric G protein-activated inward rectifier K+ (GIRK) channels, abundant in heart and brain, help to determine the cellular membrane potential as well as the frequency and duration of electrical impulses. The sequence arginine-glycine-aspartate
