Abstract
To investigate the differential expression of genes after Gum Arabic (Acacia senegal) administration by microarray study.The microarray was performed using colonic tissue of BALB/c s at 8 weeks of age treated with10% (w/w) GA dissolved in drinking water and control had a normal tap water for 4 days. A total 100 genes were analyzed by the pathway, gene ontology (GO) enrichment analysis, construction of protein-protein interaction (PPI) network, module analysis, construction of target genes-miRNA interaction network, target and genes-transcription factor (TF) interaction. We discuss key issues pertaining to experimental design, data preprocessing, and gene selection methods. Common types of data representation are illustrated. A total of 100 differentially miRNAs were screened and identified by microarray according to fold change the top genes which were significantly 59 genes with up-regulation and 41 genes down regulation, after Gum Arabic administration for 4 days. The data may unravel the future molecular mechanisms of Gum arabic by applying various bio-informatical approaches, we have revealed top score upregulation genes were 23, and down regulated genes with top score were 38. To the best of our knowledge we are the first to apply Microarray of several genes expression with their top functions after Gum arabic administration. These studies also highlighted that several additional, and as of yet unidentified, gene interactions may be responsible for the multiple beneficial effects of GA. The aim of our current study was to identify novel regulated genes, gene networks and pathways in Colonic tissue of BALB/c mice by applying microarray gene expression analysis subsequent to 4 days GA treatment.
