title: Micromanaging alternative splicing during muscle differentiation.
abstract: A recent report in Genes & Development by Boutz et al. (2007) demonstrates that muscle specific microRNAs (miRNAs) downregulate the alternative splicing regulator nPTB during skeletal muscle differentiation to control a potential network of splicing transitions. The results illustrate how two modes of posttranscriptional regulation combine to direct skeletal muscle development.
