Disrupting integrin-EDIL3 ligation deprives HCC of anoikis resistance induced by EDIL3 in SMMC-7721 and MHCC-LM3. A, Cilengitide (10 μM) reduces the WST-8 value and increased casepase3/7 of the EDIL3 overexpressing group back to levels of control group, suggesting a blockage of EDIL3’s effect. There was not any effect observed in the control group in WST-8 and caspase3/7 assay. Both the two cell lines show consistent results. B, when integrin αV was knocked down to a very low level in both cell lines by two siRNAs (Si2 and Si3), the alteration in WST-8 and casepase3/7 value of EDIL3-overexpressing cells compared with control cells disappear. Interestingly, the WST-8 value and casepase3/7 intensity results suggest the overall anoikis significantly declined upon integrin αV silencing in both siRNA knock-down groups compare with si-control group. **: P < 0.01.
