In the TCGA microarray dataset of the Oncomine database with colorectal tumor and normal colorectal tissues, significant decreases were found in the mRNA expression of MT1B (a fold change of −7.717) (Figure 3A), MT1F (a fold change of −6.946) (Figure 3B), MT1G (a fold change of −10.010) (Figure 3C), MT1H (a fold change of −9.898) (Figure 3D), MT1L (a fold change of −9.108) (Figure 3E), and MT1X (a fold change of −5.364) (Figure 3F) in CRC tissues (n = 101) compared to normal colon tissues (n = 19). Here, MT1B is linked to colorectal carcinoma.
