However, the molecular basis for sex disparity in SLE remains poorly understood. To examine the role of X-linked transcription in SLE adaptive immune cells, we performed RNA-seq in T cell and B cell subsets from either healthy donors or patients with SLE. Analyses of allelic expression (AE) profiles identified a pattern of increased allelic imbalance across the entire X chromosome in SLE lymphocytes. X-linked genes exhibiting AE in SLE had an extensive overlap with genes known to escape X chromosome inactivation (XCI). XIST RNA was overexpressed in SLE patients. Differential XIST expression correlated with AE profiles more positively at X-linked genes than the genome-wide background. Analysis of three independent RNA-seq data verified the XIST-associated skewed AE on X chromosome in SLE. Integrative analyses of DNA methylation profiles showed an increased variability of DNA methylation levels at these AE-related X-linked genes. In cultured lymphoblastic cells, knockdown of XIST specifically altered allelic imbalance patterns between X chromosomes. Our study provides genetic evidence that upregulation of XIST accompanied with more skewed allelic expression on X chromosome is associated with the pathogenesis of SLE and may provide mechanistic insights into the increased incidence of SLE in females.<\/jats:p>","DOI":"10.1093\/hmg\/ddaa131","type":"journal-article","created":{"date-parts":[[2020,7,2]],"date-time":"2020-07-02T19:11:59Z","timestamp":1593717119000},"page":"2523-2534","source":"Crossref","is-referenced-by-count":24,"title":["Skewed allelic expression on X chromosome associated with aberrant expression of XIST on systemic lupus erythematosus lymphocytes"],"prefix":"10.1093","volume":"29","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3859-3839","authenticated-orcid":false,"given":"Yanfeng","family":"Zhang","sequence":"first","affiliation":[{"name":"HudsonAlpha Institute for Biotechnology, Huntsville, AL 35806, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xinrui","family":"Li","sequence":"additional","affiliation":[{"name":"Division of Clinical Immunology and Rheumatology, Department of Medicine, University of Alabama at Birmingham, Birmingham, AL 35294, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew","family":"Gibson","sequence":"additional","affiliation":[{"name":"Division of Clinical Immunology and Rheumatology, Department of Medicine, University of Alabama at Birmingham, Birmingham, AL 35294, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeffrey","family":"Edberg","sequence":"additional","affiliation":[{"name":"Division of Clinical Immunology and Rheumatology, Department of Medicine, University of Alabama at Birmingham, Birmingham, AL 35294, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert P","family":"Kimberly","sequence":"additional","affiliation":[{"name":"Division of Clinical Immunology and Rheumatology, Department of Medicine, University of Alabama at Birmingham, Birmingham, AL 35294, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Devin M","family":"Absher","sequence":"additional","affiliation":[{"name":"HudsonAlpha Institute for Biotechnology, Huntsville, AL 35806, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2020,7,6]]},"reference":[{"key":"2020090402222846000_ref1","doi-asserted-by":"crossref","first-page":"404","DOI":"10.1016\/j.cell.2015.03.025","article-title":"Systematic discovery of Xist RNA binding proteins","volume":"161","author":"Chu","year":"2015","journal-title":"Cell"},{"key":"2020090402222846000_ref2","doi-asserted-by":"crossref","first-page":"542","DOI":"10.1038\/nrg3035","article-title":"Gene silencing in X-chromosome inactivation: advances in understanding facultative heterochromatin formation","volume":"12","author":"Wutz","year":"2011","journal-title":"Nat.
