miRNAs in colorectal cancer

Sunday 5 January 2014


- MicroRNAs (or miRNAs) are small transcripts of 20-24 nucleotides that have emerged as important regulators of gene expression in cancer cells.
- Overexpression of specific miRNAs has been linked to the stepwise disease progression during the normal-adenoma-cancer sequence in the colorectal cancer (CRC).
- Given their cancer-specific pattern of expression, remarkable stability and presence in blood and other body fluids, miRNAs are considered to be highly promising cancer biomarkers.

- Some infrequently expressed miRNAs, when expressed at higher levels, appear to have significant biological meaning in terms of tumor molecular phenotype and gene expression profiles. (28548123)
