Researchers have used designer molecules to correct problems with a cellular process associated with breast cancer and many other diseases.

Called pre-messenger RNA splicing, the process is part of the method cells use to create proteins.

Pre-messenger RNA is a representation of a DNA sequence that, for reasons scientists don’t completely understand, contains excess information. Pre-messenger RNA splicing removes the excess information to produce messenger RNA, which forms templates that cells use to make proteins.

Genetic mutations can cause errors in the splicing process, producing messenger RNA that in turn causes the production of abnormal proteins.
