Project description:p/CIP binds to many nuclear receptors and plays a major role in hormone dependent transcription of genes. Recently, p/CIP was shown to affect mouse stem cell pluripotency. Microarray gene expression analysis was conducted to assess the role of p/CIP in mouse embryonic stem cells.

Project description:To know whether the microarray technique could be used to detect bacterial gene expression in soil, large quantity of RNA was extracted from soil cultures of Pseudomonas putida KT2440 containing a chloroaromatic degrading plasmid at the presence or absence of the growth substrate, 3-chlorobenzoate (3CB). The quality and quantity of the extracted RNA were proper for a typical microarray analysis. Gene expression patterns of soil cultures were analyzed by DNA microarray using the extracted RNA. Among 5346 genes on the array, 5% and 4.5% of genes showed up- or down-regulation. Analysis done at the DAVID Bioinformatics Resources server suggested that the benzoate degradation via hydroxylation pathway had the most significant changes after treatment with 3CB. Expression of the 3CB degradation genes located in the genome was confirmed by real-time RT-PCR. In addition, real time RT-PCR analysis revealed that the fluorescent signals from plasmid genes on the microarray were saturated so that the induction ratio of the genes located in the plasmid was underestimated in microarray analysis. To our best knowledge, this report represents the first trial to use microarray technique to detect genome-wide bacterial gene expression in soil. A study using total RNA extracted from soil cultures of Pseudomonas putida KT2440/pSL1. Each chip measures the expression level of 5,341 genes from Pseudomonas putida KT2440 genome and 5 genes from an introduced plasmid pSL1 with fourteen 60-mer probes per gene which have five-fold technical redundancy.

Project description:Genome-wide scanning of gene expression by microarray techniques was successfully performed on RNA extracted from a sterilized soil inoculated with Pseudomonas putida KT2440/pSL1, which contains a chloroaromatic degrading plasmid, in the presence or absence of 3-chlorobenzoic acid (3CB). The genes showing significant changes in their expression in both triplicate microarray analyses using amplified RNA and single microarray analysis using unamplified RNA were investigated. Pathway analysis revealed that the benzoate degradation pathway underwent the most significant changes following treatment with 3CB. Analysis based on categorization of differentially expressed genes against 3CB revealed new findings about the cellular responses of the bacteria to 3CB, including upregulation of the genes specifically involved in transport of 3CB, and induction of a K+/H+ antiporter complex, an universal stress protein, two cytochrome P450 proteins and an efflux transporter. Downregulated expression of some genes involved in carbon metabolism and the genes belong to a prophage in the presence of 3CB was observed. This study demonstrated the applicability of the method of soil RNA extraction for microarray analysis through a proof-of-concept experiment using a sterilized soil inoculated with Pseudomonas putida KT2440/pSL1. A study using total RNA extracted from soil cultures of Pseudomonas putida KT2440/pSL1. Each chip measures the expression level of 5,341 genes from the Pseudomonas putida KT2440 genome with two sets of six 60-mer probes per gene.

Project description:Heart failure is characterized by the inability of the heart to pump effectively and generate proper blood circulation to meet the body's needs; it is a devastating condition that affects more than 100 million people globally. In spite of this, little is known about the mechanisms regulating the transition from cardiac hypertrophy to heart failure. Previously, we identified a cardiomyocyte-enriched gene, CIP, which regulates cardiac homeostasis under pathological stimulation. Here, we show that the cardiac transcriptional factor GATA4 binds the promotor of CIP gene and regulates its expression. We further determined that both CIP mRNA and protein decrease in diseased human hearts. In a mouse model, induced cardiac-specific overexpression of CIP after the establishment of cardiac hypertrophy protects the heart by inhibiting disease progression toward heart failure. Transcriptome analyses revealed that the IGF, mTORC2 and TGFβ signaling pathways mediate the inhibitory function of CIP on pathologic cardiac remodeling. Our study demonstrates GATA4 as an upstream regulator of CIP gene expression in cardiomyocytes, as well as the clinical significance of CIP expression in human heart disease. More importantly, our investigation suggests CIP is a key regulator of the transition from cardiac hypertrophy to heart failure. The ability of CIP to intervene in the onset of heart failure suggests a novel therapeutic avenue of investigation forthe prevention of heart disease progression.

Project description:p/CIP binds to many nuclear receptors and plays a major role in hormone dependent transcription of genes. Recently, p/CIP was shown to affect mouse stem cell pluripotency. Microarray gene expression analysis was conducted to assess the role of p/CIP in mouse embryonic stem cells. p/CIP was downregulated using two different siRNAs and total RNA was extracted and hybridized to a microarray. As control, wild type cells were transfected with pooled non specific siRNAs. The expression difference was calculated between the control wild-type cells and cells having p/CIP downregulation. The experiments were carried out at London Regional Genomic Centre (http://www.lrgc.ca/).
