Gene expression changes associated with resistance to intravenous corticosteroid therapy in children with severe ulcerative colitis

Project description:Although corticosteroids remain a mainstay of therapy for UC, a meta-regression of cohort studies in acute severe ulcerative colitis (UC) showed that 29% of patients fail corticosteroid therapy and require escalation of medical management or colectomy. We aimed to determine whether genes expressed in whole blood early following initiation of intravenous corticosteroid treatment can be associated with response. 20 corticosteroid responsive (PUCAI < 35 by day 5) and 20 corticosteroid resistant patients (PUCAI ≥ 35 by day 5 and need for 2nd line medical therapy or colectomy by hospital discharge) were selected from a prospectively accrued cohort of patients hospitalized for intravenous corticosteroid treatment of severe UC. Total RNA was extracted from blood samples collected on day 3 of intravenous corticosteroid therapy. The eluted transcriptomes were quantified on Affymetrix Human Gene 1.0 ST arrays. The data was analysed by the local-pooled error method for discovery of differential gene expression and false discovery rate correction was applied to adjust for multiple comparisons. P-values less than 0.05 after correction were considered significant.

A Biodistribution Study of OTV vs. ASO by Intravenous or Intrathecal Administration in Cynomolgus Monkeys

Project description:The objective of this study is to evaluate ASO biodistribution and pharmacodynamic response following intravenous delivery of conjugated OTV, which utilizes transferrin-receptor binding to deliver ASO, vs. intrathecal delivery of naked ASO in cynomolgus monkeys, the current gold standard for ASO delivery. Three groups were included for comparison: 1) Negative control cohort = Four biweekly intravenous doses of saline (n=3); 2) IT cohort = Single intrathecal dose of 4mg MALAT1 ASO (n=3); 3)  OTV multi dose cohort = Four biweekly intravenous doses of 30mpk OTV:MALAT1 (n=3). Tissues were collected two weeks after the final dose to allow sufficient time for target knockdown. Brain, spinal cord, and peripheral tissues were dissected and frozen for molecular analysis. Compared to an intrathecal injection of ASO, systemic administration of OTV resulted in significantly more homogenous biodistribution of ASO in the central nervous system as measured by a probe-based hybridization assay as well as staining with an anti-ASO antibody. One potential consequence of heterogeneous ASO distribution is heterogeneous target knockdown throughout the CNS. We observed more consistent target knockdown throughout the cortex, subcortical areas, and spinal cord of monkeys dosed peripherally with OTV. By contrast, monkeys dosed intrathecally with naked ASO showed much more knockdown in the spinal cord compared to the brian, consistent with ASO distribution.

Gene expression profiles of 16 relapsed/refractory CLL patients treated with lenalidomide in a phase II clinical trial

Project description:The aim of the study is to identify differentially expressed genes between chronic lymphocytic leukemia (CLL) patients who will respond to lenalidomide treatment and non responsive patients. We performed a whole genome gene-expression analysis of pre-treatment samples collected from 16 CLL patients included in a phase II clinical trial. The pre-treatment sample comprises purified CD19 cells from peripheral blood. Ten (37%) patients achieved partial responses (PR) and were classified as responders (R), 2 (7%) stable diseases (SD) and 4 (15%) progressive diseases (PD) and were classified as non responders (NR). Supervised analysis identified 78 genes up-regulated and 119 genes down-regulated in R compared with NR (Fold change [FC]≥2, p<0.01, Figure 4). Different expression levels of genes involved in interferon (INF) and Wnt signaling pathways characterized patients who will respond to lenalidomide. In particular, R showed a 23-fold increase in Wnt inhibitor Shisa homolog 3 (SHISA3), whereas a decrease of WISP3, CDH4, HOXB7 and WNT10A. Moreover, leukemic cells collected from R down-regulated interferon-induced proteins (IFI44, -6.6; IFI44L, -9.3; IFIT2, -2) and STAT1 (-2.4 fold change). NR group up-regulated lipoprotein lipase (LPL, +7.5). The baseline expression levels of cereblon (CRBN) were not dissimilar between R and NR subsets

Gene expression profiles in nineteen Kawasaki Disease (KD) patients before and after intravenous immunoglobulin (IVIG) treatment

Project description:In this study, we compared global gene expressions between pre- and post- intravenous immunoglobulin (IVIG) administration in nineteen Kawasaki disease (KD) patients. Peripheral blood mononuclear cells (PBMCs) obtained from nineteen patients before and after IVIG treatment was extracted using a PAXgene blood RNA isolation kit. Amplified cRNAs of each patient were analyzed using with Agilent Whole Human Genome Microarray 4x44K G4112F array.

Intravenous lipopolysaccharide infusion and the bovine metabolome

Project description:The effects of lipopolysaccharides (i.e., endotoxin; LPS) on metabolism are poorly defined in lactating dairy cattle experiencing hyperlipidemia. Our objective was to explore the effects of acute intravenous LPS administration on metabolism in late-lactation Holstein cows experiencing hyperlipidemia. Ten non-pregnant lactating Holstein cows (273 ± 35 d in milk) were administered a single bolus of saline (3 mL of saline; n = 5) or LPS (0.375 μg of LPS/kg of body weight; n = 5). Simultaneously, cows were intravenously infused a triglyceride emulsion and fasted for 16 h to induce hyperlipidemia in an attempt to model the periparturient period. Blood was sampled at routine intervals. Changes in circulating total fatty acid concentrations and inflammatory parameters were measured. Plasma samples were analyzed using untargeted lipidomics and metabolomics. Endotoxin increased circulating serum amyloid A, LPS-binding protein, and cortisol concentrations. Endotoxin administration decreased plasma lysophosphatidylcholine (LPC) concentrations and increased select plasma ceramide concentrations. These outcomes suggest modulation of the immune response and insulin action. Lipopolysaccharide decreased the ratio of phosphatidylcholine to phosphatidylethanomanine, which potentially indicate a decrease in the hepatic activation of phosphatidylethanolamine N-methyltransferase and triglyceride export. Endotoxin administration also increased plasma concentrations of pyruvic and lactic acids, and decreased plasma citric acid concentrations, which implicate the upregulation of glycolysis and downregulation of the citric acid cycle (i.e., the Warburg effect), potentially in leukocytes. Acute intravenous LPS administration decreased circulating LPC concentrations, modified ceramide and glycerophospholipid concentrations, and influenced intermediary metabolism in dairy cows experiencing hyperlipidemia.
