Figure 9B shows the results of qPCR detection, indicating that versus the CRC stem cell group, the relative expression levels of TLR4, TNF-α, IL-1β and IL-8 in the YGS group and the Gomisin B group were significantly reduced, with highly significant statistical differences (P < 0.01). This evidence concerns the gene CXCL8 and colorectal carcinoma.
