Project description:Chayote (Sechium edule) fruits are rich in flavonoids, folate, and low-calorie food. However, studies about the flavonoids and regulatory mechanism of flavonoid synthesis in chayote fruits was still unclear. In present study, a transcriptome analysis and metabolite profiling of chayote fruits at three different storage stages were conducted to explore the flavonoid compositions and gene expression associated with flavonoid synthesis. Through the UPLC-MS/MS analysis, a total of 57 flavonoid compounds were detected. Of these, 42 flavonoid glycosides were significantly differential accumulation in chayote fruits at three different storage stages. Many genes associated with flavonoid synthesis were differentially expressed in chayote fruits at three different storage stages through RNA-seq analysis, including structural genes and some TFs. There was a high correlation between RNA-seq analysis and metabolite profiling, and the expression level of candidate genes in the flavonoid synthesis pathway were consistent with the dynamic changes of flavonoids. In addition, one R2R3-MYB transcription factor, FSG0057100, was defined as the critical regulatory gene of flavonoid synthesis. Furthermore, we treated chayote fruits during storage with phenylalanine, and the results show exogenous phenylalanine applications might promote the flavonoid synthesis. Phenylalanine is a effective additive to maintain or improve the total content flavonoids in chayote fruit during storage, can apply the phenylalanine in the postharvest storage of chayote. The above results not only make us better understand the molecular mechanism of flavonoid synthesis in chayote fruits, but also contribute to the promotion and application of chayote products.

Project description:Mucopolysaccharidosis VII (MPS VII) is due to mutations within the gene encoding the lysosomal enzyme beta-glucuronidase, and results in the accumulation of glycosaminoglycans. MPS VII causes aortic dilatation and elastin fragmentation. In this study we performed microarray analysis of ascending aortas from normal and MPS VII mice, trying to find out possible genes responsible for the phenotype observed. In addition, during our breeding strategy, we noticed that some MPS VII mice had less dilated aortas, and we proposed that an yet-unidentified gene could be responsible for the difference observed. We therefore included in the analysis two MPS VII mice with aortas that were not dilated. Total RNA extracted from ascending aortas from 3 Normal mice, 3 MPS VII mice with dilated aortas and 2 MPS VII mice with aortas that were not dilated.

Project description:We used microarray to detect pathway differences in the various brain regions in a monogenic in mucopolysaccharidosis type VII ( MPS VII ), a mouse model of a lysosomal storage disease A number of changes revealed unexpected system and process alterations, such as upregulation of the immune system with few inflammatory changes (a significant difference from the closely related MPS IIIb model), down-regulation of major oligodendrocyte genes even though white matter changes are not a feature histopathologically, and a plethora of developmental gene changes. 94 samples, no replicates, made up of half normals and half MPS mutant mice for the MPS VII mutation backcrossed on a C3h-heouj background

Project description:An initializing step in the rhizobia-legume symbiosis is the secretion of flavonoids by plants that leads to the expression of nodulation genes in rhizobia. Here we report the genome-wide transcriptional response of Bradyrhizobium japonicum to genistein, an isoflavone secreted by soybean. About 100 genes were induced in the wild type. This included all nod box-associated genes, the flagellar cluster and several genes that are likely to be involved in transport processes. To elucidate the role of known regulators, we analysed mutant strains. This revealed that the two-component response regulator NodW is essential for induction of almost all genistein-inducible genes, with the exception of 8 genes. The phenotype of the nodW mutant could be partially suppressed by overexpression of NwsB, which is also a two-component response regulator. These data indicate that genistein has a much broader function than mere induction of nod genes. Keywords: transcriptional analysis, genistein induction 3 biological replicates of wild type uninduced and wild type induced with genistein were compared.
