MicroRNA (miR-155) Linked To Shut-Down Of DNA-Repair Genes
In research:
"The study, led by researchers at the Ohio State University Comprehensive Cancer Center-Arthur G. James Cancer Hospital and Richard J. Solove Research Institute, shows that microRNA-155 (miR-155) can inhibit the activity of genes that normally correct the damage when the wrong bases are paired in DNA.
The loss or silencing of these genes, which are called mismatch repair genes, causes inherited cancer-susceptibility syndromes and contributes to the progression of colorectal, uterine, ovarian and other cancers."
"Overall, Croce says, "Our findings suggest that miR-155 expression might be an important stratification factor in the prognosis and treatment of cancer patients and provide an additional analytical test for exploring the etiology of microsatellite-instability tumors when the standard tests do not provide a conclusive diagnosis."
