IGF2 and malignant colon neoplasm: Quantitative real‐time polymerase chain reaction was used for examining the expression levels of miR‐185‐5p, IGF2, and NEAT1 in 10 colon cancer tissues and matched normal tissues, and showed a high expression of NEAT1 and IGF2 and a low expression of miR‐185‐5p in colon cancer tissues relative to the controls (Figure 1a–d).
