Project description:The experiments were carried out to further understand the mechanism of action of ILB, a low molecular weight dextran sulphate, in glial cell. The experiments were carried out with ILB concentrations that are relevant to the therapeutic concentrations of the drug. The results indicate that ILB regulates the expression of genes to enhance cell survival and differentiation is a dose dependent manner. Upstream regulator analysis indicates that the gene expression changes are due to enhanced activity of growth factors and cytokines.

Project description:Here we describe our unprecedented approach in proposing parsley (PAR) as a nutraceutical intervention in inflammatory bowel disease (IBD) using a mouse model of dextran sodium sulphate (DSS)-induced colitis, following a multi-integrated-omics analysis. PAR supplementation (n=7) significantly improved colon shortening and increased the disease activity index compared to the DSS group (n=7). The colonic transcriptome revealed the down-regulation of inflammatory cytokines, and the hepatic transcriptome and metabolome revealed the up-regulation of fatty acid synthesis genes, thereby improving body weight loss. Down-regulated cancer markers were observed in the hepatic transcriptome and proteome. A global plasma metabolite analysis indicated shifts in the citric cycle and urea cycle, implicating improved impaired glycolysis and oxidative stress. Our integration of three omics analyses highlighted the involvement of the methionine-recycling pathway and PARM-bM-^@M-^Ys role in decreasing the risk of IBD. This pioneering use of multi-integrated-omics in the evaluation of nutrientsM-bM-^@M-^Y effects on physiology is expected to be widely useful and informative, shaping the future of nutritional research.

Total hepatic and colonic RNA from each respective group were pooled (n=7). The microarray analysis was carried as out as described by Jia et al. 8 Mouse Genome 430 2.0 Array GeneChips (Affymetrix, Santa Clara, CA) containing over 30,000 gene probe sets were used for genome-wide expression profiling.

Project description:Background & Aims: Dextran sulphate sodium (DSS) induced colitis in rats is one of the most widely used models of inflammatory bowel disease. Animal models can provide new insights into the pathogenesis of intestinal inflammation, which is still unknown. We have performed a genomic analysis of the DSS rat colitis including an acute and a recovery phase. Methods: Expression profile of 6 control rats were compared with colitic rats at day 1 every other day until day 23 after DSS treatment using the GeneChip Rat Genome 230 2.0 Array (Affymetrix). Functional and pathways analysis were made with the differentially expressed genes. Experiment Overall Design: Experimental design: DSS was administered to animals in drinking water as follows:5%DSS from day 1 to 7, 3%DSS from day 8 to 15, 0% DSS from day 16 to 23. Samples were recovered at days 1, 3, 5, 7 (5%DSS), 9, 11, 13, 15 (2%DSS), 17, 19, 21 and 23 (0%DSS). According to inflammatory markers (Myeloperoxidase activity activity, body weight loss, colonic weigth/length ratio), three replicates at each time point were selected for genomic analysis and 6 control healthy rats (42 arrays). Experiment Overall Design: RNA was extracted from homogenized full-thickness colonic tissues in Trizol® reagent (Invitrogen) and purified with RNeasy affinity columns (Qiagen), according to manufacturer´s protocol. The microarray analysis was performed by Progenika Biopharma (Bilbao, Spain) on GeneChip® Rat Genome 230 2.0 Array (Affymetrix). All sample labeling (biotin), hybridization, staining and scanning procedures were carried out using Affimetrix, standard protocols (www.affymetrix.com). Normalization was carried out using Bioconductor sofware (affyPLM package).

Project description:The current trend worldwide is searching plant extracts towards prevention of neurodegenerative disorders. This study aimed to investigate the neuroprotective effect of Alpinia galanga leaves (ALE), Alpinia galanga rhizomes (ARE), Vitis vinifera seeds (VSE), Moringa oleifera leaves (MLE), Panax ginseng leaves (PLE) and Panax ginseng rhizomes (PRE) ethanolic extracts on human neuroblastoma (SHSY5Y) cells. The 1-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging of VSE and MLE were 81% and 58%, respectively. Ferric-reducing antioxidant power (FRAP) of ALE and MLE (33.57 ± 0.20 and 26.76 ± 0.30 μmol Fe(ΙΙ)/g dry wt., respectively) were higher than for the other extracts. Liquid chromatography coupled to quadrupole time-of-flight mass spectrometry (LC-QTOF/MS) revealed MLE active compounds. Intracellular study by nitro-blue tetrazolium (NBT) test showed that MLE and VSE had high O2- scavenging (0.83 ± 0.09 vs. 0.98 ± 0.08 mg/mL, respectively). MLE had the highest ROS scavenging followed by PRE (0.71 ± 0.08 vs. 0.83 ± 0.08 mg/mL, respectively), by 2,7-dichlorodihydrofluorescein diacetate (DCFHDA) assay. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) cytotoxicity and neuroprotection tests on SHSY5Y showed that PRE had a better neuroprotective effect but higher cytotoxicity compared to MLE (viable cells 51% vs. 44%, IC50 1.92 ± 0.04 vs. 2.7 ± 0.2 mg/mL, respectively). In conclusion, among the studied plants, MLE has potential for developing as a neuroprotective agent.

Project description:Increased levels of tissue inhibitor of metalloproteinase-1 (TIMP-1) have been detected in fibrotic strictures in Crohnâs disease. In a murine model of chronic inflammation, fibrosis was associated with an increase in TIMP-1 and inhibition of matrix metalloproteinase (MMP)-mediated degradation. We investigated the effect of TIMP-1 deficiency on the colonic gene expression in acute and chronic murine models of colitis, using whole genome gene expression arrays. Colitis was induced via oral administration of dextran sodium sulphate (DSS) to B6.129S4-Timp1tm1Pds/J knock-out (KO) and C57BL/6J wild-type (WT) mice. Total RNA extracted from snap frozen colon was used to analyze mRNA expression via Affymetrix Mouse Gene 1.0 ST Arrays

Project description:Colorectal cancer (CRC) was induced in Foxp3/eGFP reporter mice by the azoxymethane/dextran sulphate sodium salt (AOM/DSS) protocol. Mice were injected i.p. with the procarcinogen AOM (12.5 mg/kg of body weight). After 1 week, mice received drinking water supplemented with 2.5% DSS for 5 to 7 days, followed by 2 weeks of regular water. The DSS administration was repeated twice with 2% DSS. Mice were sacrificed at week 11 and lamina propia lymphocytes (LPLs) from the colon were isolated. CD4+FOXP3+ (eGFP+) ST2+ or ST2- Tregs were separated from colonic LPLs of CRC induced mice using a FACSAria II cell sorter. Microarray analysis was performed to analyze if ST2+ FOXP3+ Tregs from the colon of CRC mice present a distinct transcription pattern compared to ST2- FOXP3+ Tregs. By this, the role of ST2 for Treg function during intestinal tumorigenesis should be characterized.

Project description:siRNA knockdown of NONO mRNA followed by RNA-seq was carried out in the KELLY neuroblasotma cell line. In order to determine potential regulatory targets of NONO protein, we performed differential expression analysis. To identify the RNA targets of NONO in neuroblastoma, we carried out PAR-CLIP (Photoactivatable Ribonucleoside-Enhanced Crosslinking and Immunoprecipitation) using an antibody recognising NONO protein.

Project description:To understand the mechanism of action of ILB we have used gene expression analysis to document the changes induced by the drug in Schwann like cells. Human Schwann-like cells (ATCC-CRL-2884) were treated with ILB (0.01 mg/ml) for 48 hours. Control samples were cultured parallel with no drug added. The expression data was used to identify the ILB-regulated genes.

Project description:The lack of suitable animal models reflecting chronically relapsing inflammation and tissue remodeling have hindered fibrosis research in inflammatory bowel diseases (IBD). This study investigated changes in connective tissue in a chronic murine model using different cycles of dextran sodium sulphate (DSS) to mimic the relapsing nature of the disease. We used whole gene expression arrays to study differences in colonic gene expression levels between acute and more chronic DSS colitis,
