CCL26 and neoplasm: Figure 3C indicates a positive correlation between the expression of the eight genes ADPRH, CD4, CR1, CR2, LIG4, CD8A, HSF1, and ZNF846 and the IC50 of 28 medications; that is, it shows a positive relationship between the expression of the eight genes and tumor resistance to the treatments. Moreover, the expression of 11 genes (namely MX1, CFH, CD46, CD55, TM9SF2, TMED10, CCL26, CXCL1, CXCL8, CYB5R3, EXT1, and IL6) was negatively correlated with the IC50 of 28 drugs in tumors, i.e., the tumor resistance to these drugs was negatively correlated with the expression of these genes.
