Interleukin-6 Promotes Epithelial-Mesenchymal Transition and Cell Invasion through Integrin β6 Upregulation in Colorectal Cancer

IL-6 promotes invasion of human CRC cells through IL-6R. (a) Transwell invasion assays to assess the effect of IL-6 with different concentrations on the invasion of HT-29 and Colo205 cell lines for 24 h. (b–d) Transwell invasion assays to validate the role of IL-6R in IL-6-induced cell invasion. CRC cells were pretreated for 1 h and maintained thereafter with neutralizing antibody (10 μg/ml) of IL-6R (b) or pretreated for 24 h with siRNA targeting IL-6R (c, d) to inhibit IL-6R, followed by stimulation with 20 ng/ml IL-6 for 24 h. (a, b, d) Data represent the . independent experiments. versus no IL-6 treatment control. # versus IL-6-treated group. (c) Data shown is representative of 3 independent experiments.
