Outline of Final Research Achievements |
Mismatch repair-deficient colorectal cancers display widespread instability at DNA microsatellite sequences (MSI). But MSI has been reported to commonly occur at coding repeats, leading to alterations in the function of a number of genes encoding cancer-related proteins, nothing is known about the putative impact of this process on non-coding microRNAs. We considered whether genetic mutation due to MSI changed the structure of miRNA hairpin loop by using thermodynamic free energy.Our results provide evidence that DNA repeats contained in human miRNA gene are relatively rare and preserved from mutations due to MSI.
