RT Journal Article T1 Downregulated microRNAs in the colorectal cancer: diagnostic and therapeutic perspectives. A1 Hernandez, Rosa A1 Sanchez-Jimenez, Ester A1 Melguizo, Consolacion A1 Prados, Jose A1 Rama, Ana Rosa K1 Biomarkers K1 Colorectal cancer K1 Diagnosis K1 miRNA K1 Therapeutic target AB Colorectal cancer (CRC), the third most common cancer in the world, has no specific biomarkers that facilitate its diagnosis and subsequent treatment. The miRNAs, small single-stranded RNAs that repress the mRNA translation and trigger the mRNA degradation, show aberrant levels in the CRC, by which these molecules have been related with the initiation, progression, and drug-resistance of this cancer type. Numerous studies show the microRNAs influence the cellular mechanisms related to the cell cycle, differentiation, apoptosis, and migration of the cancer cells through the post-transcriptionally regulated gene expression. Specific patterns of the upregulated and down-regulated miRNA have been associated with the CRC diagnosis, prognosis, and therapeutic response. Concretely, the downregulated miRNAs represent attractive candidates, not only for the CRC diagnosis, but for the targeted therapies via the tumor-suppressing microRNA replacement. This review shows a general overview of the potential uses of the miRNAs in the CRC diagnosis, prognosis, and treatment with a special focus on the downregulated ones.
