Abstract

MicroRNAs are noncoding RNAs that regulate multiple cellular processes during cancer progression. Among various microRNAs, miR-630 has recently been identified to be implicated in many critical processes in human malignancies. We investigated the expression pattern and prognostic value of miR-630 in human colorectal cancer by utilizing cancer and adjacent normal specimens from 206 patients. Quantitative real-time PCR assay was used to detect the expression of miR-630, and appropriate statistical analysis was used to evaluate the association of miR-630 with overall survival. It was found that miR-630 expression was significantly increased in colorectal cancer specimens compared with that in adjacent normal specimens. It was also proved that miR-630 expression in colorectal cancer was associated with tumor invasion, lymph node metastasis, distant metastasis, and tumor-node-metastasis (TNM) stage. The Kaplan-Meier survival analysis proved that increased miR-630 expression was associated with poor overall survival of patients with colorectal cancer. Multivariate analysis proved that miR-630 was an independent prognostic marker after adjusted for known prognostic factors. These results confirmed the overexpression of miR-630 in human colorectal cancer and its association with tumor progression. It also suggested that miR-630 expression might serve as a prognostic biomarker for patients with colorectal cancer.
