Figure 1. Fourteen out of twenty m6A RNA methylation regulatory genes are differentially expressed in KIRP tissues. (A) The heatmap demonstrates the expression of 20 m6A RNA methylation regulators in 289 KIRP and 32 normal kidney tissue samples from the TCGA database. The color bar from red to green denotes high to low gene expression. * P<0.05; ** P<0.01; *** P<0.001. (B) The boxplots show the expression of 14 differentially expressed m6A RNA methylation regulators in normal kidney and KIRP tissues from the TCGA database.
