Biologists discover a new type of control over RNA splicing

Biologists have identified a new type of regulation that influences the expression of about half of all human genes by targeting specific introns. This discovery adds complexity to the process of gene expression and suggests potential therapeutic targets for diseases such as blood cancers and spinal muscular atrophy.
