Abstract 484: Epigenetic regulation of hsa-miR-3663 in colon cancer
2017
Colon Cancer is the third most common cancer in the world and a major cause of morbidity and mortality. Molecular mechanisms of colon carcinoma have been deeply studied and current evidences indicate that microRNAs play a pivotal role in its tumorigenesis and progression. MicroRNAs (miRNAs) are small 19 to 22 nucleotides of RNA classified as non-coding RNAs that negatively regulate gene expression at the post-translational level controlling numerous biological processes including development, cell proliferation, apoptosis, differentiation and cell migration. Aberrant expression of miRNAs due to epigenetic alterations has been associated with carcinogenesis. Aimed to identify epigenetically regulated miRNAs involved in colon cancer, we analyzed DNA methylation profiles available in The Cancer Genome Atlas. One of the main hits identified was hsa-miR-3663, hypermethylated in 26% of colon cancer patients (n=286, p Note: This abstract was not presented at the meeting.
