Prognostic risk signature based on the expression of three m6A RNA methylation regulatory genes in kidney renal papillary cell carcinoma

Figure 2. PPI network and Pearson correlation analyses of 14 differentially expressed m6A RNA methylation regulatory genes. (A) PPI network of the 14 differentially expressed m6A RNA methylation regulatory genes. (B) Pearson correlation analysis of the 14 differentially expressed m6A RNA methylation regulatory genes in the TCGA-KIRP cohort. Note: ‘r’ denotes Pearson correlation co-efficient whose value ranges between -1 (perfect negative correlation) and +1 (perfect positive correlation).
