Boxplot, volcano plot, and heatmap of gene expression of the dataset GSE84078. Box and whisker plot of GSE84078 before normalization (A) and after normalization (B). Volcano plot of old and young groups (C). Heatmap for selected differentially expressed genes between old and young ovary groups. A total of 931 DEGs are screened in normal old and young mice ovaries. A process of gradual color change from red to blue indicates expression values changing from high to low (D). DEGs, differentially expressed genes; FC, fold change.
