Hypomethylation of miR-17-92 cluster in lupus T cells and no significant role of genetic factors in the lupus-associated DNA methylation signature

Comment on: Coit, et al., Ann Rheum Dis 16 June 2022. doi:10.1136/annrheumdis-2022-222656 Comment by: Marta E. Alarcón-Riquelme Epigenetics, and particular the study of the methylation of the CpG nucleotides in DNA has shown that lupus CD4+ T cells have aberrant methylation patterns1 and are poised towards activation of interferon-regulated genes2. DNA methylation is an important … Read more
