Expression validation of key genes. a The mRNA expression of key genes in multiple cancer types from the Oncomine database. The number in the cells represents the number of analyses meeting the thresholds. Red indicates a higher expression level of target genes in tumour tissues than in normal tissues, and blue indicates an opposite expression pattern. The colour depth of each cell indicates the gene rank, and the deeper the colour depth is, the higher the gene rank. b The mRNA expression of key genes in multiple cancer types from GEPIA
