SLC9D1 and neoplasm: We obtained TMCO3 mRNA expression levels from the TCGA database and investigated them to identify differential expression patterns between tumor and normal tissues and found that in several tumor tissues, the expression of TMCO3 was higher than in the respective normal adjacent tissues, including ESCA, COAD, GBM, HNSC, LIHC, and LUAD (Figure 1A).
