Project description:Many genes involve in pathogenicity and virulence are induced only in plant or in the presence of host components. Bean leaf extract was obtained from healthy bean leaves. In this work we investigated the effect of bean leaf extract on the transcriptomic profile of the bacterium, when grown at low temperature in minimal medium with or without extract from healthy bean leaves.
Project description:The water extract of the leaf of B. racemosa had been reported to posses high phenolic content and showed high antioxidant activities. However, scientific data on the molecular mechanisms underlying the beneficial properties of the leaf extract are still lacking. In this study, the effects of the leaf extract on the expression of genes in cultured HepG2 cells were investigated using microarray technology. The leaf extract significantly regulated the expression of genes involved with consequential impact on the glycolysis, gluconeogenesis and metabolism of xenobiotics.
Project description:The leaf extract of T. indica had been reported to posses high phenolic content and showed high antioxidant activities. However, scientific data on the molecular mechanisms underlying the beneficial properties of the leaf extract are still lacking. In this study, the effects of the leaf extract on the expression of genes in cultured HepG2 cells were investigated using microarray technology. The leaf extract significantly regulated the expression of genes involved with consequential impact on the coagulation system, cholesterol biosynthesis, xenobiotic metabolism signaling and antimicrobial response.
Project description:To get deeper insights into the GSH-triggered systemic defense signaling events in plants, we performed transcriptome profiling on leaf 6 collected after one hour application of GSH to leaf 1 of WT plants. To further investigate the relations between GSH and Glu in plant wound response, we generated transcriptome data sets from leaf 6 one hour after wounding leaf 1 or application of Glu to leaf 1 of WT plants.
Project description:The water extract of the leaf of B. racemosa had been reported to posses high phenolic content and showed high antioxidant activities. However, scientific data on the molecular mechanisms underlying the beneficial properties of the leaf extract are still lacking. In this study, the effects of the leaf extract on the expression of genes in cultured HepG2 cells were investigated using microarray technology. The leaf extract significantly regulated the expression of genes involved with consequential impact on the glycolysis, gluconeogenesis and metabolism of xenobiotics. HepG2 cells were seeded and treated with an 50 µg/ml of the water leaf extract of B. racemosa for 24 h. Following this, cells were trypsinized and then preciptated by centrifugation. Cells were washed with phosphate buffer saline (PBS) before total cellular RNA (tcRNA) were extracted from the cells. tcRNA from both untreated and B. racemosa leaf-treated HepG2 cells were selected for RNA extraction and hybridization on Affymetrix microarrays. All experiments were done in triplicate. The microarray analysis was performed on Affymetrix Human Gene 1.0 S.T Array according to the manufacturer's protocol. The gene sets were then subjected to analysis of variance (ANOVA) in the Partek Genomics Suite software to determine significantly expressed genes which was set according to P value less than 0.05 and fold change difference of equal to or greater than 1.5.
Project description:We investigated the effect of pterocarpan-rich extract from soybean leaf on metabolic syndrome and elucidated anti-inflammation mechanism based on RNA-seq transcriptomic profiles in overweight and obese subjects
Project description:The leaf extract of T. indica had been reported to posses high phenolic content and showed high antioxidant activities. However, scientific data on the molecular mechanisms underlying the beneficial properties of the leaf extract are still lacking. In this study, the effects of the leaf extract on the expression of genes in cultured HepG2 cells were investigated using microarray technology. The leaf extract significantly regulated the expression of genes involved with consequential impact on the coagulation system, cholesterol biosynthesis, xenobiotic metabolism signaling and antimicrobial response. HepG2 cells were seeded and treated with an IC20 concentration of the methanol leaf extract of T. indica for 24 h. Following this, cells were trypsinized and then preciptated by centrifugation. Cells were washed with phosphate buffer saline (PBS) before total cellular RNA (tcRNA) were extracted from the cells. tcRNA from both untreated and T. indica leaf-treated HepG2 cells were selected for RNA extraction and hybridization on Affymetrix microarrays.
