View SamplesGlobal gene expression in TET2 mutant and Wild type patients. We performed an integrated analysis of global DNA methylation and gene expression data to investigate the effects of DNA hypermethylation on gene expression.

View SamplesResting B cells were isolated from WT or KMTD KO mice by immunomagentic depletion of with anti-CD43 beads. Gene expression use determined by RNAseq in resting B cells or B cells stimulated with LPS, IL4, and anti-mouse CD180 for 3 days. Overall design: RNAseq was used to profile unstimulated resting B cells (n=3) and B cells stimulated for 3 days (n=3).
The histone lysine methyltransferase KMT2D sustains a gene expression program that represses B cell lymphoma development.

View SamplesWe report here senescent changes in the structure and organization of the mucociliary pseudostratified epithelium of the mouse trachea and the main stem bronchi. We confirm previous reports of the graduate appearance of age-related, gland-like structures (ARGLS) in the submucosa, espeically in the intercartilage regions and carina. Immunohistochemistry shows these structures contain ciliated and secretory cells and Krt5+ basal cells, but not the myoepithelial cells or ciliated ducts typical of normal submucosal glands. Data suggests they arise de novo by budding from teh surface epithelium rather than by delayted growth of small or cryptic submucosal glands. In old mice the surface epithelium contains fewer cells per unit length than in young mice and the proportion of Krt5+, p63+ basal cells is reduced in both males and females. However, there appears to be no significant difference in the ability of basal stem cells isolated from individual young and old mice to form clonal tracheospheres in culture or in the ability of the pithelium to repair after damage by inhaled sulfur dioxide. Gene expression analysis by Affymetrix microarray and quantitative PCR, as well as immunohistochemistry and flow sorting studies, are consistent with low-grade chronic inflammation in the tracheas of old versus young mice. The significance of these changes for ARGL formation are not clear since several treatments that induce acute inflammation in young mice did not result in budding of the surface epithelium.

View SamplesThe conducting airway epithelium of the rodent and human lung is made up of about equal proportions of ciliated and secretory cells. In addition, in regions where the epithelium is pseudostratfied, ~30% of the epithelium consists of undifferentiated basal cells (BCs). Evidence suggests that these BCs are multipotent stem cells that can self renew over the long term and give rise to both ciliated and secretory lineages. The goal of this project is to identify cellular and molecular mechanisms by which the basal cells normally maintain the epithelium and repair it after injury.

View SamplesThe conducting airway epithelium of the rodent and human lung is underlaid by mesenchymal cells that include vasculature, smooth muscle, fibroblasts and cartilage. The goal of this project is to identify cellular and molecular changes in the mesenchyme after injury to the epithelium by exposure to SO2 and which may participate in repair of the epithelium

View SamplesWe identified DCIR2+DCs but not DEC205+DCs as able to induce peripheral T cell tolerance in pre-diabetic autoimmune NOD mice. To determine what distinct genetic programs are elicited in the auto-reactive CD4 T cells early after stimulation by these two DC subsets, we utilized adoptive transfer of BDC2.5 CD4 T cells into NOD mice, which were then given chimeric antibody to deliver the beta-cell specific antigen to either DCIR2+DCs or DEC205+DCs, leading to BDC2.5 CD4 T cell specific stimulation in vivo. The analysis shows that the negative transcriptional factor Zbtb32 (ROG) is up-regulated more in BDC2.5 CD4 T cells after stimulated with a antigen via DCIR2+DCs presentation, compared with DEC205+DCs, suggesting the involvement of Zbtb32 in DCIR2+DCs-mediated auto-reactive T cell tolerance in disease ongoing NOD mice.

View SamplesWe investigated the global gene expression changes in normal and Brg1-deleted mesoderm differentiation of mouse embryonic stem cells. Overall design: RNAseq analysis of poly-adenylated RNA levels for 3 conditions: Day2 of differentiation, Day4 THF (Control), and Day4 4OHT (Brg1-deleted). 2 replicates per condition.

View SamplesObesity-associated metabolic complications are generally considered to emerge from abnormalities in carbohydrate and lipid metabolism, whereas the status of protein metabolism is not well studied. Here, we performed comparative polysome and associated transcriptional profiling analyses to study the dynamics and functional implications of endoplasmic reticulum (ER)-associated protein synthesis in the mouse liver under conditions of obesity and nutrient deprivation.
