The ovulation assessment of regular cyclic rats following subacute oral administration of monosodium glutamate: An in vivo study [PDF]
Journal of Pharmacy & Pharmacognosy Research, 2022 Context: The possible toxic effects of monosodium glutamate (MSG) on ovarian functions have not been thoroughly evaluated in contrast to testicular functions. Few studies documented that MSG showed histological alterations.

cAMP Pulsing of Denuded Mouse Oocytes Increases Meiotic Resumption Via Activation of AMP-activated Protein Kinase [PDF]
, 2009 cAMP plays a critical role in the control of oocyte maturation, as a high level of cAMP maintains oocyte arrest at the first meiotic prophase. Yet this study shows that pulsing meiotically arrested denuded oocytes (DO) with cAMP induces oocyte maturation

AMPK Regulation of Mouse Oocyte Meiotic Resumption in Vitro [PDF]
, 2006 We have previously shown that the adenosine analog 5-aminoimidazole-4-carboxamide-1-β-d-ribofuranoside (AICAR), an activator of AMP-activated protein kinase (AMPK), stimulates an increase in AMPK activity and induces meiotic resumption in mouse oocytes ...

Oocyte Competence Biomarkers Associated With Oocyte Maturation: A Review [PDF]
Frontiers in Cell and Developmental Biology, 2021 Oocyte developmental competence is one of the determining factors that influence the outcomes of an IVF cycle regarding the ability of a female gamete to reach maturation, be fertilized, and uphold an embryonic development up until the blastocyst stage.

Suppression of Chemically Induced and Spontaneous Mouse Oocyte Activation by AMP-Activated Protein Kinase [PDF]
, 2013 Oocyte activation is an important process triggered by fertilization that initiates embryonic development. However, parthenogenetic activation can occur either spontaneously or with chemical treatments.
