We were able to obtain RNA-seq data from 26 normal-tumor matched samples of colon adenocarcinoma (COAD) from TCGA and determine normalized expression values of SLC22A18. Consistent with RT-PCR results from our patient samples, virtually all tumor tissues showed lower expression of SLC22A18 than matched normal tissues (Figure 1C). The gene discussed is SLC67A1; the disease is colon adenocarcinoma.
