For LoVo cells, the mean anti-adhesion efficacy of G6-5S, G6-5A and G6-5A-5S were 44.90%, 61.09% and 65.70%, respectively (Figure 6b), suggesting that antiEpCAM and antiSlex antibodies might play the synergistic effects in inhibiting the adhesion of cancer cells to Fn-coated substrates, and the antiEpCAM was the key factor with this respect. This evidence concerns the gene FN1 and cancer.
