FABP1 and colorectal carcinoma: We also present in boxplot visualizations comparisons of the expressions of FABP genes in normal, colon adenocarcinoma (COAD), and rectal adenocarcinoma (READ) tissues (Figure 4), which showed that the FABP1, FABP4, and FABP6 genes had significantly different expression levels in normal and CRC tissues (Figure 4A).
