We revealed that stromal expression of COL6A3 was upregulated significantly in the CRC tissues comparing with the normal tissues (p = 2.4E-13) (Figure 5E), whereas the epithelial expression of COL6A3 was downregulated in the CRC tissues (p = 3.7E-20) (Figure 5F). The gene discussed is COL6A3; the disease is colorectal carcinoma.
