Quercetin is a plant-derived flavonoid found in fruits or vegetables that has antioxidant properties and acts as a free radical scavenger. We investigated the effects of quercetin on porcine oocyte nuclear maturation and embryonic development after parthenogenetic activation. We then evaluated the antioxidant activities of quercetin by measuring reactive oxygen species (ROS) levels in matured o...
An extended meiotic prophase is a hallmark of oogenesis. Hormonal signaling activates the CDK1/cyclin B kinase to promote oocyte meiotic maturation, which involves nuclear and cytoplasmic events. Nuclear maturation encompasses nuclear envelope breakdown, meiotic spindle assembly, and chromosome segregation. Cytoplasmic maturation involves major changes in oocyte protein translation and cytoplas...
This study to do examine the effectiveness of using heparin and hypotaurine improve in vitro fertilization rate. In first stage, oocytes were matured maturation medium supplemented with 0.3 mg/mL L-carnitine nuclear maturation. second fertilized semen incubated 0.1 IU/mL 10 µM hypotaurine. The final concentration sperm used was 5x106 spermatozoa/mL, its interaction carried out for 12 hours 5% C...
BACKGROUND Oocyte maturation and competence to development depends on its close relationship with cumulus cells (CCs). However, the maturation conditions of human cumulus-oocyte complexes (COCs) might affect gene expression in both oocyte and CCs. We thus compared the transcriptome profiles of CCs isolated from in vivo and in vitro matured COCs at different nuclear maturation stages. METHODS ...
Dendritic cell (DC) maturation is critical for initiation of the adoptive immune response. DC maturation is often attenuated in several pathological conditions including cancer. In this study, we report the effect of Platycodon grandiflorum polysaccharide (PG) on DC maturation. PG induced phenotypic maturation of DCs, as proved by the increase in the expression of CD40, CD80, CD86, and major hi...
