Expression and methylation data from SLE patient and healthy control blood samples subdivided with respect to ARID3a levels

Ward, J.M., Ratliff, M.L., Dozmorov, M.G. et al.

Previously published studies revealed that variation in expression of the DNA-binding protein ARID3a in B lymphocytes from patients with systemic lupus erythematosus (SLE) correlated with levels of disease activity ("Disease activity in systemic lupus erythematosus correlates with expression of the transcription factor AT-rich-interactive domain 3A" (J.M. Ward, K. Rose, C. Montgomery, I. Adrianto, J.A. James, J.T. Merrill et al., 2014) [1]). The data presented here compare DNA methylation patterns from SLE peripheral blood mononuclear cells obtained from samples with high numbers of ARID3a expressing B cells (ARID3a(H)) versus SLE samples with normal numbers of ARID3a(+) B cells (ARID3a(N)). The methylation data is available at the gene expression omnibus (GEO) repository, "Gene Expression Omnibus: NCBI gene expression and hybridization array data repository" (R. Edgar, M. Domrachev, A.E. Lash, 2002) [2]. Isolated B cells from SLE ARID3a(H) and ARID3a(N) B samples were also evaluated via qRT-PCR for Type I interferon (IFN) signature and pathway gene expression levels by qRT-PCR. Similarly, healthy control B cells and B cells stimulated to express ARID3a with the TLR agonist, CpG, were also compared via qRT-PCR. Primers designed to detect 6 IFNa subtype mRNAs were tested in 4 IFNa, Epstein-Barr Virus-transformed B cell lines ("Reduced interferon-alpha production by Epstein-Barr virus transformed B-lymphoblastoid cell lines and lectin-stimulated lymphocytes in congenital dyserythropoietic anemia type I" (S.H. Wickramasinghe, R. Hasan, J. Smythe, 1997) [3]). The data in this article support the publication, "Human effector B lymphocytes express ARID3a and secrete interferon alpha" (J.M. Ward, M.L. Ratliff, M.G. Dozmorov, G. Wiley, J.M. Guthridge, P.M. Gaffney, J.A. James, C.F. Webb, 2016) [4].
