miR-139-5p was downregulated in colorectal cancer.
(A) Heat map. miRNA microarray analyses were performed in six paired tumour and normal tissues. The green in the legend represents downregulation and the red represents upregulation. (B) Determination of miR-139-5p expression levels in eight colon cell lines and NCM460 cells (meanā±āSEM). (C,D) Downregulation of miR-139-5p expression in primary colorectal cancer tissue compared their normal tissue (paired Studentās t-test). (E) miR-139-5p expression levels decreased significantly with the advance of the tumour stage.
