Characteristics of and differences between transcriptomes from normal and abnormal human oocytes. (A) The majority of the genes were protein-coding genes. (B) Principal component analysis (PCA). (C) Heatmap of differentially expressed genes in each comparison group. The genes with P value < 0.05 and |log2 fold change|≥1 according to differential expression analysis were extracted, and heatmaps were generated to visualize the expression of each sample. Blue indicates a lower expression level, and red indicates a higher expression level. (D) Volcano map of differentially expressed genes
