(Submitter supplied) Epigenetic alternations in addition to genetic factors are important contributors to the pathogenesis of Systemic Lupus Erythematosus (SLE). Recent studies revealed that aberrant changes in DNA methylation occur in SLE patients, and potentially contributes to the pathogenesis. Using genome-wide DNA methylation microarray, the Illumina Infinium HumanMethylation450 BeadChip, we compared the DNA methylation level of white blood cells between Chinese female SLE patients with that of healthy controls. more...

(Submitter supplied) Our study has demonstrated that significant number of differential genes in SLE was involved in IFN, TLR signaling pathways and inflammatory cytokines. The enrichment of differential genes has been associated with aberrant DNA methylation, which may be relevant to the pathogenesis of SLE. Our observations laid the groundwork for further diagnostic and mechanistic studies of SLE and LN.

(Submitter supplied) Objective: Systemic lupus erythematosus (SLE) has limited monozygotic (MZ) twin concordance, implying a role for other pathogenic factors than genetic variation, such as epigenetic changes. Using the disease discordant twin model, we investigated genome-wide DNA methylation changes in sorted CD4+ T-cells, monocytes, granulocytes and B-cells in twin pairs with at least one SLE-affected twin. Methods: Peripheral blood from 15 SLE twin pairs (six MZ, nine dizygotic (DZ)) was processed using gradient density centrifugation for the granulocyte fraction. more...

(Submitter supplied) Background: Patients with paediatric-onset systemic lupus erythematosus (SLE) often present with more severe clinical courses than adult-onset patients. Although genome-wide DNA methylation (DNAm) profiling has been performed in adult-onset SLE patients, parallel data on paediatric-onset SLE are not available. Therefore, we undertook a genome-wide DNAm study in paediatric-onset SLE patients across multiple blood cell lineages. more...

(Submitter supplied) This study performed Illumina Methylation450 analysis of CD4+ T-cells, CD19+ B-cells and CD14+ Monocytes from lupus patients and controls. A validation cohort was further analyzed with the same platform using CD4+ T-cells, CD45RO-CD45RA+ naive T-cells, CD45RO+CD45RA- memory T-cells, and CD25+CD127- regulatory T-cells.

(Submitter supplied) Systemic lupus erythematosus (SLE) is a chronic-relapsing autoimmune disease of incompletely understood etiology. Recent evidence strongly supports an epigenetic contribution to the pathogenesis of lupus. To understand the extent and nature of dysregulated DNA methylation in lupus T cells, we performed a genome-wide DNA methylation study in CD4+ T cells from 12 lupus patients and 12 normal healthy controls. more...

(Submitter supplied) SLE patients are always with various disease manifestation. Various cytokines are pointed interacting and playing pathological roles in SLE although the etiopathology is still obscure. In this study, we aimed to investigate the effects of cytokine interactions in the immune response of SLE patients. Overexpressed interferon-inducible(IFI) genes were confirmed in peripheral blood from SLE patients. Using network-based analysis on the immune response-related genes, several networks including cytokines such as TNF and IFN-γ, or beta-estradiol(E2), were constructed. more...
