Metabolic reprogramming in the cumulus cells of aged infertile patients after DHEA treatment. (a) Mitochondrial function was determined by oxygen consumption rate (OCR), through utilizing the Seahorse Bioscience Analyzer. (b-g) All of the OCR values at different phases of basal respiration, maximal respiration, ATP-coupled respiration, and spare capacity, proton leak and noon-mitochondrial respiration were recorded, and the values were calculated among the young, aged and aged/DHEA groups. Oligomycin (1 uM), FCCP (1 uM), antimycin (0.5 uM), rotenone (0.5 uM). * p < 0.05 and ** p < 0.01.
