P-144: Glucose-6-Phosphate Dehydrogenase Activity in Ovine Oocytes in Association with Developmental Characteristics and Expression of Bax Gene
Background: Recent studies have revealed that oocyte competence can be assessed through the presence of the glucose-6-phosphate dehydrogenase (G6PDH) enzyme, as indicated by brilliant cresyl blue (BCB), a dye that can be degraded by G6PDH. In the present study, we aimed to examine the validity of BCB test to select developmentally competent oocyte in ovine and its association with stage-specifi...
متن کاملP-90: Effect of Phosphodiesterase Type3 Inhibitor, Cilostamide, on The Developmental Competence of Ovine OocytesIsolated by Glucose 6-Phosphate Dehydrogenase Activity
Background: The developmental competence of oocytes matured in vitro (IVM) is yet far below than in vivo counterparts. Recent studies suggest that the asynchrony between nuclear/cytoplasmic maturation and the initial low/heterogeneous quality of oocytes are the most important factors affecting IVM success. We investigated whether selection of growing oocytes (based on their glucose 6- phosphate...
متن کاملGlucose-6-Phosphate Dehydrogenase
Description Glucose-6-Phosphate Dehydrogenase (G6PD) deficiency is the most common human enzyme deficiency that mainly affects the red blood cells (RBCs). A defect in G6PD enzyme leads to the destruction of premature RBCs causing hemolytic anemia because the body can not compensate the destroyed RBCs. Thus, the affected individuals show jaundice (paleness, yellowing of the skin and whites of th...
متن کاملINHIBITION OF HUMAN ERYTHROCYTE GLUCOSE 6-PHOSPHATE DEHYDROGENASE ACTIVITY BY DEHYDROEPIANDROSTERONE AND RELATED STEROIDS.
The inhibitory effects of several steroids on G6PD activity using intact erythrocytes are reported. Incubation of whole blood with dehydroepiandrosterone (DHEA) resulted in 42% and 12% inhibition in the enzyme activity in the presence and absence of oxygen, respectively. Addition of epinephrine and/or aminophylline into the incubation medium caused further enzyme inhibition suggesting a po...
متن کاملImportance of glucose-6-phosphate dehydrogenase activity in cell death.
The intracellular redox potential plays an important role in cell survival. The principal intracellular reductant NADPH is mainly produced by the pentose phosphate pathway by glucose-6-phosphate dehydrogenase (G6PDH), the rate-limiting enzyme, and by 6-phosphogluconate dehydrogenase. Considering the importance of NADPH, we hypothesized that G6PDH plays a critical role in cell death. Our results...
