Description
Hyperthyroidism is a kind of common autoimmune disease. It is widely accepted that B lymphocytes play a significant role in GD as they are the source of autoantibodies (TRAb) against the thyroid-stimulating hormone receptor (TSHR). We previously observed B cells infiltrated in the thyroid tissue from GD patients was significantly higher than that in healthy controls.In this study, our flow cytometry results indicated that the proportion of B cells in GD patients is much higher than that in control. To explore the underlying pathological function of B cells in GD, a microarray profiles was performed in these isolated B cells.

Description
The renewing human epidermis constantly senses and adapts to a wide range of mechanical cues that are ubiquitous throughout life. The mechanisms of how mechanical forces are responded by interfollicular epidermal stem cells (IFESCs) and are transmitted directly into nucleus to modify gene expression remain incompletely defined. In vitro, human IFESCs were cultured on the collagen I coated silicon rubber membrane and then subjected to the mechanical stretched. Cyclic mechanical tension at 0.5 Hz sinusoidal curve at 10% elongation was applied using an FX-5000T Flexercell Tension Plus unit (Flexcell International Corporation). In mechanical unloading groups, cells were cultured on the same plates in the same incubator with the mechanical stretched groups but not subjected to stretch. Combining genome-wide microarray and functional analyses, we made transcriptome analysis of samples from the mechanical unstretched or stretched isolated human IFESCs.

Description
Hyperphosphatemia is an independent risk factor for cardiovascular mortality in chronic kidney disease. High inorganic phosphorus can induce endothelial cell apoptosis, but the exact mechanism is not fully understood. This study addresses this knowledge gap.Microarray analysis was used to identify differentially expressed gene profiles in human umbilical vein endothelial cells (HUVECs) in high phosphate (3.0 mM) normal phosphate (1.0 mM) medium and low phosphate( 0.5mM).

Rheumatoid arthritis (RA) is a systemic autoimmune disease and its underlying molecular mechanisms are still poorly understood. Previously a CD4 T-cell microarray study has only focused arthritis patients. We aimed to compare the molecular profiles of active RA versus healthy control in CD4 T cells.

Description
DNA methylation of C5-cytosine (5mC) in the mammalian genome is a key epigenetic event that is critical for various cellular processes. However, how the genome-wide 5mC pattern is dynamically regulated remains a fundamental question in epigenetic biology. The TET family of 5mC hydroxylases, which convert 5mC to 5-hydroxymethylcytosine (5hmC), have provided a new potential mechanism for the dynamic regulation of DNA methylation. The extent to which individual Tet family members contribute to the genome-wide 5mC and 5hmC patterns and associated gene network remains largely unknown. Here we report genome-wide mapping of Tet1 and 5hmC in mESCs and reveal a mechanism of action by which Tet1 controls 5hmC and 5mC levels in mESCs. In combination with microarray and mRNA-seq expression profiling, we identify a comprehensive yet intricate gene network influenced by Tet1. We propose a model whereby Tet1 controls DNA methylation both by binding to CpG-rich regions to prevent unwanted DNA methyltransferase activity, and by converting the existing 5mC to 5hmC through its enzymatic activity. This Tet1-mediated antagonism of CpG methylation imparts differential maintenance of DNA methylation status at Tet1 target loci, thereby providing a new regulatory mechanism for establishing the epigenetic landscape of mESCs, which ultimately contributes to mESC differentiation and the onset of embryonic development.

Description
Histone methylation occurs on both lysine and arginine residues and its dynamic regulation plays a critical role in chromatin biology. Here we identify the UHRF1 PHD domain (PHDUHRF1), an important regulator of DNA CpG methylation, as an unanticipated histone H3 unmodified arginine 2 (H3R2)-recognition modality. This conclusion is based on binding studies and co-crystal structures of the PHDUHRF1 bound to histone H3 peptides, where the guanidinium group of unmodified R2 forms an extensive intermolecular hydrogen bond network, with methylation of H3R2, but not H3K4 or H3K9, disrupting complex formation. We have identified direct target genes of UHRF1 from microarray and ChIP studies. Importantly, we show that UHRF1s ability to repress its direct target gene expression is dependent on PHDUHRF1 binding to unmodified H3R2, thereby demonstrating the functional importance of this recognition event and supporting the potential for crosstalk between histone arginine methylation and UHRF1 function.
