Key Advance Toward Treatment For Most Common Adult Form Of Muscular Dystrophy - Journal Of The American Chemical Society
In the study, Benjamin Miller and colleagues point out that MMD differs from typical hereditary diseases. They result from mutated DNA in genes that encodes an erroneous message that RNA picks up and passes along. As a result, cells produce faulty proteins. Those proteins disrupt cells' activity and cause symptoms of the disease. Rather, MMD is caused by wayward or "toxic" strands of RNA.
The researchers describe discovery of a family of drug-like molecules that target the errant strands of RNA, preventing production of the defective protein. The discovery, they said, provides scientists for the first time with substances that target the root cause of MMD and represent molecules that could be developed into drugs. They note that drugs more commonly target DNA or proteins, with the RNA approach offering a different and potentially valuable route to developing new medications for certain diseases.
