Circulating plasma MiR-141 is a novel biomarker for metastatic colon cancer and predicts poor prognosis.

ABSTRACT:

Background

Colorectal cancer (CRC) remains one of the major cancer types and cancer related death worldwide. Sensitive, non-invasive biomarkers that can facilitate disease detection, staging and prediction of therapeutic outcome are highly desirable to improve survival rate and help to determine optimized treatment for CRC. The small non-coding RNAs, microRNAs (miRNAs), have recently been identified as critical regulators for various diseases including cancer and may represent a novel class of cancer biomarkers. The purpose of this study was to identify and validate circulating microRNAs in human plasma for use as such biomarkers in colon cancer.

Methodology/principal findings

By using quantitative reverse transcription-polymerase chain reaction, we found that circulating mi
