New research shows for the first time that molecules called microRNA can silence genes that protect the genome from cancer-causing mutations. 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...
