Interestingly, a significant correlation was found between the expression of TGF-β, IL-6, TLR-2 and TLR-4 by the primary CRC tumor and FN1 expression in the metastatic intrahepatic tumor (Figure 6F–I) but no correlation to the local primary CRC tumor (Figure 6J–M). The gene discussed is TGFB1; the disease is colorectal carcinoma.
