The number of genes changed according to the DAVID analysis in POA oocytes after NMN treatment. (A–D) Categories are divided to derive the “Oxidative stress,” “Mitochondrial functions and fission,” “Mitophagy and autophagy,” and “Apoptotic process.” The values in the square box under each category showed the accuracy of RNA-seq log2 expression. The graphs indicate the number of various genes (upregulated: red; downregulated: blue; Total: green) between the IVM and POA-induced model compared with NMN exposed groups (0–44 h: M, 44–68 h: A, and 0–68 h: M + A of IVM). The graphs were considered genes with more than 1.5-fold and adjusted p-value < 0.05.
