The Impact Of Myeloperoxidase And Its Related Oxidants On Metaphase Ii Mouse Oocyte Quality
We investigated the ability of reactive oxygen species (ROS), such as hydrogen peroxide (H2O2), hydroxyl radical (OH), and hypochlorous acid (HOCl) to overcome the defensive capacity of cumulus cells, and elucidate the mechanism through which ROS differentially deteriorate oocyte quality. Metaphase II mouse oocytes with (n=1634) and without cumulus cells (n=1633) were treated with increasing co...
متن کاملThe Impact of Myeloperoxidase and Activated Macrophages on Metaphase II Mouse Oocyte Quality
Myeloperoxidase (MPO), an abundant heme-containing enzyme present in neutrophils, monocytes, and macrophages, is produced in high levels during inflammation, and associated with poor reproductive outcomes. MPO is known to generate hypochlorous acid (HOCl), a damaging reactive oxygen species (ROS) utilizing hydrogen peroxide (H2O2) and chloride (Cl-). Here we investigate the effect of activated ...
متن کاملSituations Leading to Oxidative Stress in Dairy Cattle
Free radicals are normally produced by living organism, at controlled production rate they perform physiological functions as signal transduction molecules. However, situations leading to an overproduction that surpasses antioxidant capacity creates oxidative stress. Consequently, damage to the cell membrane, protein, DNA and cell death are observed. Dairy cattle are susceptible to oxidative st...
متن کاملChromatin Spread Preparations for the Analysis of Mouse Oocyte Progression from Prophase to Metaphase II.
Chromatin spread techniques have been widely used to assess the dynamic localization of various proteins during gametogenesis, particularly for spermatogenesis. These techniques allow for visualization of protein and DNA localization patterns during meiotic events such as homologous chromosome pairing, synapsis and DNA repair. While a few protocols have been described in the literature, general...
متن کاملthe vitrification of metaphase ii mouse oocyte using ethylene glycol as cryoprotectant
introduction: the purpose of this study was to investigate the effect of vitrification procedure on the survival, fertilization, development and ultrastructure of metaphase (mii) mouse oocyte. materials and methods: female nmri mice 6-10 weeks old were superovulated using ip injection of 10 iu hmg and 10 iu hcg. ovulated oocyte were collected from the ampullary portion of the oviducts at 12-13 ...
