U-M researchers discover gene switched off in cancer can be turned on

...from lung, esophageal, ovarian, bladder, colon and breast cancers. The researchers were able to use existing drugs, which showed some usefulness in turning on the BRM gene. But new drugs would need to be developed to be more effective in reactivating this gene in cancer cells. Still, researchers are exci...
