RNA-seq and ChIRP-seq analysis performed on Charme muscle specific lnc-RNA


ABSTRACT: The main function of chromatin-associated long non coding RNAs (lncRNA) is to tether specific combinations of regulatory factors to target genomic sites. Here we show the characterization of a conserved lncRNA, Charme, that acts as an architectural scaffold to bring together distantly located genomic loci. The functional knock-down of Charme revealed a direct link between the formation of chromosomal loops and the down-regulation of genes therein contained, which are crucial for the correct control of muscle homeostasis. Notably, several Charme-target genes were previously linked to human cardiomyopathies and Charme deficiency in mice indeed resulted in a very strong cardiac phenotype. Altogether, these data disclose that the chromosomal architecture controlled by Charme is relevant for fine tuning the myogenic programme and for proper tissue homeostasis in vivo.
