Hierarchical clustering heatmap related to overlapping DEGs.

Heatmap related to the expression profile of 57 common DEGs between three resistant and three sensitive HT-29 cells from the microarray (A) GSE42387 and (B) GSE76092 datasets. Red and blue pixels indicate the over- and under-expression of NNMT, SLC14A1, and TFF2 genes in oxaliplatin-resistant cells, respectively. The above-mentioned genes exhibit reverse expression pattern in two datasets to down-regulate in GSE42387 and up-regulate in GSE76092. DEG: Differentially expressed gene.
