miR-491 is downregulated in CRC tissues. (A) miR-491 expression was significantly decreased in 457 cancer tissues compared with 8 normal tissues. (B) Expression of miR-491 in the early (T1/2) and late T stages (T3/4). (C) Expression of miR-491 in the early (N) and late N stages (N1/2). miR, microRNA; CRC, colorectal cancer.
