PRMT4 is a novel coactivator of c-Myb-dependent transcription in haematopoietic cell lines.

Protein arginine methyltransferase 4 (PRMT4)-dependent methylation of arginine residues in histones and other chromatin-associated proteins plays an important role in the regulation of gene expression. However, the exact mechanism of how PRMT4 activates transcription remains elusive. Here, we identify the chromatin remodeller Mi2α as a novel interaction partner of PRMT4.

E-box-independent regulation of transcription and differentiation by MYC.

MYC proto-oncogene is a key player in cell homeostasis that is commonly deregulated in human carcinogenesis(1). MYC can either activate or repress target genes by forming a complex with MAX (ref. 2).

Epigenetics and senescence: learning from the INK4-ARF locus.

Cellular senescence is the biological consequence of aging. However, the same mechanisms that provoke senescence during aging have been proven to act in tumor suppression and thus to occur in premalignant cells. All the diverse aspects of the senescent phenotype, as are observed for many other cell fates, arise from alterations of the chromatin architecture.
