Chains of small RNA cause cancer cells to self destructResearchers from the California Institute of Technology, with support from the National Science Foundation (NSF), have developed conditional small RNA molecules that could treat cancer cells without causing negative side effects. Cancer is a personal disease that varies with each case and is based on one's own environmental and genetic factors. It is normally treated with chemotherapy, which consists of giving patients one or more types of drugs in hopes of this diagnosing and treating cancer cells.
