    ..This is the first direct demonstration that DNA methylation of exon-encoding regions is directly involved in regulation of alternative splicing. ..
  2. Naftelberg S, Schor I, Ast G, Kornblihtt A. Regulation of alternative splicing through coupling with transcription and chromatin structure. Annu Rev Biochem. 2015;84:165-98 pubmed publisher
    ..We focus on evidence for how the kinetics of RNA polymerase II (RNAPII) elongation and the recruitment of splicing factors and adaptor proteins to chromatin components act in coordination to regulate alternative splicing. ..

    ..Our results demonstrate DNA methylation's significant global influence on mRNA splicing and identify a specific mechanism of splicing regulation mediated by HP1. ..

    ..These two mechanisms, however, regulate only a fraction of such events, implying that more underlying mechanisms remain to be found. ..

    ..Therefore, compounds that activate the MAPK/ERK signaling pathway could constitute potential treatments for FD. ..

    ..Our results suggest that PS has potential for use as a therapeutic agent for FD. Understanding its mechanism of action may reveal the mechanism underlying the FD disease. ..

    ..Our findings suggest that the association of SF3B1 with nucleosomes is functionally important for splice-site recognition and that SF3B1 conveys splicing-relevant information embedded in chromatin structure. ..

    ..This may explain how RNAPII and chromatin are involved in spliceosome assembly and how introns lengthened during evolution with a relatively minimal compromise in splicing. ..
