(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) 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) Systemic lupus erythematosus (SLE) is a chronic relapsing autoimmune disease characterized by the production of autoantibodies and multiple organ involvement. In this study, we investigated genome-wide DNA methylation changes in the CD8+ T cells from 8 pairs of lupus patients compared to age, sex, and ethnicity matched healthy controls.

(Submitter supplied) Male patients with systemic lupus erythematosus (SLE) experience severe disease compared to female patients, despite the disease being more prevalent in females. For the time, we compared genome-wide differential methylation in CD4+ T cells between male (n=12) and female (n=10) SLE patients.

We investigated changes in the methylome in isolated circulating CD4+ T cells in non-pregnant and pregnant women, during the 1st and 2nd trimester, using the Illumina Infinium Human Methylation 450K array, and explored how these changes were related to autoimmune diseases that are known to be affected during pregnancy. more...

(Submitter supplied) Background/Purpose: Systemic lupus erythematosus (SLE) is a complex multi-system autoimmune disease of uncertain etiology. Patients from different ancestral backgrounds demonstrate differences in clinical manifestations and autoantibody profiles. In this study we examined genome-wide transcriptional patterns in major immune cell subsets across different ancestral backgrounds. Methods: Peripheral blood was collected from 21 African-American (AA) and 21 European-American (EA) SLE patients, 5 AA controls, and 5 EA controls. more...

(Submitter supplied) We compared genomic DNA methylation patterns and gene expression in African American children with persistent atopic asthma versus healthy controls. We identified 119 differentially methylated regions (DMRs) and 118 differentially methylated probes (DMPs) after adjustment for age, gender, race/ethnicity, batch effects, inflation, and multiple comparisons (false discovery rate-adjusted q<0.05). Genes differentially methylated include those with established roles in asthma and atopy, components of the extracellular matrix, genes related to immunity, cell adhesion, epigenetic regulation, and airway obstruction. more...

We hypothesized that epigenetic marks regulate gene expression of the nasal epithelia and consequently may provide a novel target for allergic asthma.
