The colon cancer cells lines used were HT-29, SK-CO-1 and WiDr. 1Real-time PCR was used to determine miRNA and target mRNA levels; the log2 (fold change) values are shown. 2Western blotting was used to determine protein levels and the values were expressed relative to those of normal tissues. In both real-time PCR and western analysis, data were derived from three independent experiments. **p < 0.01.
