The Hox cluster microRNA miR-615: a case study of intronic microRNA evolution

<strong>Background: </strong> Introns represent a potentially rich source of existing transcription for the evolution of novel microRNAs (miRNAs). Within the Hox gene clusters, a miRNA gene, miR-615, is located within the intron of the Hoxc5 gene. This miRNA has a restricted phylogenetic...
