Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
The objective of this experiment was to determine global gene expression change in triple negative cell line upon knockdown of TGFBR3. Genotype specific differences in expression profiles have been evaluated using human HuGene1.0-ST affymetrix array. RNA was extracted from SUM159 controls and SUM159 TGFBR3KD cells cultured in 3-dimensional in vitro system.

Description
Epigenetic alterations may provide important insights into gene-environment interaction in inflammatory bowel disease (IBD). Here we observe epigenome-wide DNA methylation differences in 240 newly-diagnosed IBD cases and 190 controls. These include 439 differentially methylated positions (DMPs) and 5 differentially methylated regions (DMRs), which we study in detail using whole genome bisulphite sequencing. We replicate the top DMP (RPS6KA2) and DMRs (VMP1, ITGB2, TXK) in an independent cohort.

Description
Norwalk virus (NV) is a prototype strain of the noroviruses (family Caliciviridae) which have emerged as major causes of acute gastroenteritis worldwide. We have developed NV replicon systems using reporter proteins such as a neomycin resistant protein (NV replicon-bearing cells) and a green fluorescent protein (pNV-GFP), and demonstrated that these systems were excellent tools to study virus replication in cell culture. In this study, we first performed DNA microarray analysis of the replicon-bearing cells to identify cellular factors associated with NV replication. The analysis demonstrated that genes in lipid (cholesterol) or carbohydrate metabolic pathways were significantly (p< 0.001) changed by the gene ontology analysis. Among genes in the cholesterol pathways, we found that mRNA levels of hydroxymethylglutaryl-CoA (HMG-CoA) synthase, squalene epoxidase and acyl-CoA:cholesterol acyltransferase(ACAT) 1, ACAT 2, small heterodimer partner, and low density lipoprotein receptor (LDLR)-related proteins were significantly changed in the cells.

Description
Oxidative injury and inflammation have been implicated in the genesis of hypertension but the mechanisms involved are not fully understood. We describe a new pathway in which angiotensin II promotes dendritic cell (DC) activation of T cells and ultimately hypertension. NADPH oxidase-dependent superoxide production is increased 5-fold in DCs isolated from hypertensive mice as compared to sham-treated mice. This is associated with DC accumulation of protein-isoketal adducts and production of IL-6, IL-1 and IL-23. DCs from hypertensive mice but not sham mice promote survival and proliferation of CD8+ T cells in culture. Chemically diverse isoketal scavengers not only prevent activation and immunogenicity of DCs, but also attenuate angiotensin II-induced hypertension. Moreover, adaptive transfer of DCs from hypertensive mice prime development of hypertension in response to a subpressor dose of angiotensin II. Exposure of DCs to tert butyl hypdroperoxide promoted isoketal formation, DC stimulation of CD8+ T cell proliferation and primed hypertension in response to low dose angiotensin II. Serum isoprostanes, precursors to isoketals, were found to be elevated in humans with treated hypertension and were markedly elevated in patients with resistant hypertension. These studies show that angiotensin II-induced hypertension activates DCs, in large part by causing superoxide production and formation of isoketals. They define a new mechanism of hypertension and identify a potential new therapeutic approach for this disease.

Description
Vascular smooth muscle cells (VSMCs) are derived from distinct embryonic origins. Vessels originating from differing smooth muscle cell populations have distinct vascular and pathological properties of calcification, atherosclerosis, and structural defects such as aneurysm and coarctation. We hypothesized that domains within a vessel vary in phenotype based on embryonic origin.

Description
The ductus arteriosus (DA) is a fetal vascular shunt that is located between the main pulmonary artery and the aorta. Oxygenated fetal blood from the placenta is shunted past the uninflated fetal lungs, crosses the DA, and is then available to the peripheral organs. In utero closure of the DA is deleterious, but postnatal closure of the DA is necessary for establishment of pulmonary circulation and the transition to newborn life.
