Significance of LINC00641 and miR-378 as a potential biomarker for colorectal cancer

AbstractIn colorectal cancer (CRC), dysregulation of noncoding RNA expression is a distinguishing factor. Owing to the conflicting results and the insufficient studies on serum microRNA-378 (miR-378) and long intragenic noncoding RNA00641 (LINC00641) expression patterns, we aimed to explore their expression profiles and diagnostic ability in colorectal cancer.  Blood samples were collected from 30 healthy controls and 70 CRC patients. miR-378 and LINC00641 expression levels were determined using quantitative real-time reverse transcription-polymerase chain reaction (qRT-PCR), carcinoembryonic antigen (CEA) levels assessed by the enzyme-linked immunosorbe nt assay (ELISA) method. The expression levels of the studied miR-378 and LINC00641 correlated with patients’ CEA levels. LINC00641 expression was dramatically upregulated, and miR-378 expression was significantly downregulated in colorectal cancer compared to the healthy controls. The differentia l expression of miR-378 and LINC00641 was inversely correlated, whereas the expression folds of both LINC00641 and CEA directly correlated with the advanced stages of colorectal cancer. Receiver operator characteristic (ROC) curve analysis disclosed the highest diagnostic potential for LINC00641 to discriminate colorectal cancer patients from the control and the highest diagnostic potential for discrimination between colorectal cancer stages.
