Characterization of metabolic patterns in porcine cumulus cells during meiotic maturation
Copyright © 2024 Elsevier Inc. All rights reserved..
Metabolic coupling between oocytes and the surrounding somatic cells allows for normal two-way communication, and their interactions is necessary for generating developmentally competent eggs. However, the metabolic framework that support oocyte maturation in surrounding cumulus cells is still lacking. Herin, we established a temporal metabolome profile of porcine cumulus cells at three key stages during oocyte maturation, illustrating the picture of global metabolic network in cumulus cells. Importantly, we discovered the novel metabolic signature in cumulus cells during meiotic maturation, in specific, significant consumption of fatty acids, elevated activity of hexosamine biosynthetic pathway (HBP), and enhanced polyamine biosynthesis. Meanwhile, we observed the different utilization of tryptophan, active biosynthesis of progesterone, and progressive decrease in purine and pyrimidine metabolism as the oocytes progress through meiosis. Collectively, our metabolomic data serves an entree to elaborate on the dynamic changes in these metabolic pathways, which not only reveals the metabolic networks controlling oocyte development, but also lays a foundation for the discovery of biomarkers in the improvement in porcine oocyte culture system.
