MIR20A and colonic neoplasm: When comparing mean expression levels of the eight analyzed miRNAs between incident colon cancer cases and healthy controls, we observed that almost all miRNAs (Let7, Mir21, Mir155, Mir181, Mir222, Mir145, and Mir20) were upregulated in controls, while only one miRNA (Mir92) showed a higher mean expression level in cases compared to controls.
