miR-522-3p was highly expressed in human colorectal cancer (CRC) tissues and cell lines. (A) Expression of miR-522-3p in 15 paired CRC tissues and matched adjacent nontumor tissues was measured by quantitative real-time polymerase chain reaction (qRT-PCR). (B) Expression of miR-522-3p in normal human colon epithelial cell line (FHC) and five human CRC cell lines (LoVo, HCT-116, HT29, SW480, and SW620) was measured by qRT-PCR. *p < 0.05, **p < 0.01, ***p < 0.001.
