Androgen receptor (AR)-mediated oncogenic pathways have not been fully elucidated. In this study, we used high-throughput microarray analysis on two AR-positive prostate cancer (CaP) cell lines to identify 16 AR-responsive microRNAs (miRNA). We focused on miR-21 because of its previously reported oncogenic activity in other cancers. We show androgen-induced AR binding to the defined miR-21 promoter, miPPR-21, suggesting direct transcriptional regulation. Inhibition of miR-21 diminished androgen- ...[more]

Project description:Objective is to identify microRNAs regulated by KIT signaling in mast cells. miRNA profiles of murine bone marrow derived mast cells with and without SCF treatment were compared. In addition, miRNA profiles of the P815 mutant KIT cell line with and without the KIT inhibitor, imatinib, were compared. We identified miRNAs that were differentially regulated by KIT signals. Two systems were used to identify microRNAs regulated by KIT. RNA was collected from primary murine bone marrow derived mast cells (BMMC) treated and not treated with KIT ligand (SCF). In addition, RNA was harvested from the P815 (activating KIT mutation positive) cell line treated and not treated with the KIT inhibitor, imatinib. Samples were harvested after 24 hours of treatment

Project description:Human bone marrow mesenchymal stromal cells are capable of limited self-renewal and multi-lineage differentiation in vitro. Several studies have demonstrated that microRNAs, post-transcriptional modifiers of protein expression, play crucial roles in the regulation of these complex processes. To gain knowledge regarding the role of microRNAs in human adipocyte regulation, we examined the microRNA expression profile of the immortalized human bone marrow-derived stromal cell line hMSC-Tert20. We identified 12 microRNAs that were differentially expressed during adipogenesis, of which several have previously been shown to play important roles in adipocyte biology. The expression of miR-155, miR-221 and miR-222 decreased during the adipogenic program, suggesting that they act as negative regulators of differentiation. Interestingly, adenovirus-mediated expression of either miR-155 alone or miR-221 plus miR-222 significantly inhibited adipogenesis and repressed induction of the master regulators C/EBP? and PPAR?. Our study provides the first experimental evidence that miR-155, miR-221 and miR-222 function in human adipocyte differentiation. The telomerase immortalized human bone marrow-derived stromal cell line hMSC-Tert20 was differentiated towards adipocytes, and total RNA was harvested at various time points (0, 8, 24, 32, 48 and 72 hours, and 7, 14 and 21 days). All hybridizations, except for 0h, 8h and 32h, were performed twice. The expression of each miRNA at a given time point was calculated as a ratio relative to its level on day 0. No dye swaps.

Project description:Intracellular pH affects many cellular systems but its mechanisms of regulation and perception are mostly unknown. Weak organic acids such as acetate are potent fungistatic agents used in food preservation, but their intracellular targets are poorly understood. We thus searched for transcriptional response in Saccharomyces cerevisiae to intracellular acidification caused by two hours 30mM acetic acid treatment. Two independent experiments were performed for both acid-treated/non-treated cells. The experimental design for both cases was a Balanced Block Design with four biological replicates, two of them dye swaps.

Project description:293 cells were tranfected with Myc-tagged argonaute family members and associated microRNAs quantitated by microarray analysis of immunoprecipitates. Human argonaute 1, 2, and 3, and a control immunoprecipitation were done. Two independent immunoprecipitations were performed, with two replicate points per immunoprecipitation. Ch1and Ch2 net values are median intensity, background subtracted, unnormalized. Normalized Ch2 values for argonaute immunoprecipitations are median center normalized. Normalized Ch2 values for control immunoprecipitates are normalized by a constant that is the average of the constants used for argonaute immunoprecipitates.

Project description:The function of the Staphylococcus aureus eukaryotic-like serine/threonine protein kinase PknB was investigated by transcriptome analysis using DNA-microarray technology and biochemical assays. The transcriptional profile reveals a strong regulatory impact of PknB on the expression of genes encoding proteins which are involved in purine and pyrimidine biosynthesis, cell wall metabolism, autolysis, and glutamine synthesis. To investigate the functional role of PknB in S. aureus DNA microarray experiments were performed. In this experiment, the impact of the deletion of PknB was investigated. Each experiment was performed 5 times including a dye swap resulting in five chips per competitive comparison to increase reproducibility. All hybridizations were done with equal amounts of cDNA probes.

Project description:β-lapachone (b-lap) is an anticancer agent that selectively induces cell death in human cancer cells. A mechanism for b-lap cytotoxicity was shown to be mediated by the NQO1 NAD(P)H dehydrogenase and radical oxygen species (ROS) generation in several tumour cells. To further characterise the molecular effects of b-lap action, we compared the gene expression profile of yeast cells treated or not with b-lap using cDNA microarrays. Genes involved in tolerance to oxidative stress were enriched in the set of differentially expressed genes. Accordingly, b-lap treatment generated reactive oxygen species (ROS), which were efficiently blocked by dicoumarol, and inhibitor of NADH dehydrogenases (NADH-DH). In addition, a mutant defective in the mitocondrial NADH dehydrogenase Nde2p was found to be resistant to b-lap treatment, thus resembling tumour cell responses to b-lap exposure. However, b-lap treatment elicited similar ROS production in WT and nde2 cells, and dicoumarol did not affect cell viability in b-lap treated yeasts. Most interestingly, DNA damage responses triggered by b-lap were abolished in the nde2 mutant. Furthermore, the nde2 mutant was sensitive to DNA damaging agents other than b-lap. These data indicated that ROS production did not mediate b-lap cytotoxicity and highlighted a role of Nde2p in DNA damage checkpoints. Amino acid biosynthesis genes were also differentially expressed in b-lap treated cells, suggesting that b-lap exposure somehow triggered the General Control of Nutrients (GCN) pathway. Supporting this, b-lap treatment increased phosphorylation of eIF2 alpha in a Gcn2p-dependent manner. eIF2alpha phosphorylation required Gcn1p and Gcn20p and surprisingly Nde2p. Gcn2p was also shown to be required for the G1 checkpoint triggered by b-lap and for cell survival. Remarkably, b-lap treatment also increased phosphorylation of eIF2 alpha in breast tumour cells, which was partially dependent on the Nde2p orthologue AMID. These findings i) suggest that Gcn2p and Nde2p are key determinants of b-lap toxicity in yeast and human cells, ii) uncover a new functional connection between Nde2p, Gcn2p and DNA damage checkpoints conserved throughout evolution and iii) suggest that pharmacological modulation of Gcn2p could provide an effective strategy for antitumour drug discovery. Direct comparison between wt samples and b-lapachone treated-wt samples. Four biological replicates. Dye was swapped in two of them

Project description:The goal of this experiment was to identify gene expression changes that are common in different heart failure (HF) types or specific to an etiology of HF. HF groups studied include doxorubicin induced cardiomyopathy, familial dilated cardiomyopathy, hypertrophic cardiomyopathy, idiopathic dilated cardiomyopathy, ischemic heart disease, peripartum cardiomyopathy, and viral induced cardiomyopathy. Non-diseased left ventricles (LV) were obtained from donor hearts not used for transplantation (these were considered to be unsuitable for transplantation for a variety of reasons including the lack of a tissue-compatible recipient). Failing LV were obtained from patients undergoing heart transplantation. Transmural sections of LV anterior free wall were trimmed of fat, dissected into 1-1.5 gm pieces, and immediately frozen in the operating theater. 100-200 mg of frozen transmural LV was ground to a fine powder in liquid nitrogen using a mortar and pestle. Then total RNA was isolated by a method described by Wei and Khan (A Molecular Cloning Manual). The purity of the RNA extract was assessed by measuring the absorbance at 260 nm and 280 nm. Its quantity and integrity was then examined using RNA Nano Chips on a 2100 Bioanalyzer (Agilent Technologies, Palo Alto, CA, USA). 10 ?g of RNA extracts and a universal human reference RNA (Stratagene, La Jolla, CA, USA) were reverse transcribed with Cy3-dUTP and Cy5-dUTP, respectively, to produce labeled cDNA probes using Thermoscript reverse transcriptase according Hwang JJ et. al. (Physiological Genomics 10: 31-44, 2002). Raw scanned images were processed using ScanAlyze version 2.50 (Michael Eisen, Stanford University, CA, USA). Cy3 and Cy5 scans were superimposed, local backgrounds were subtracted, and the fluorescence intensities of each spot were quantified. All further analyses of CardioChips were done using GeneSpring version 6.1 (Silicon Genetics, Redwood City, CA, USA). The data from each array was normalized first to the reference RNA and then a LOWESS curve was fit to the log-intensity versus log-ratio plot for each array and for each gene across all experiments. 40.0% of the data was used to calculate the LOWESS fit at each point. Differentially expressed genes in each HF group compared to donor hearts were identified by a one-way ANOVA test (P <0.05) with the benjamini and hochberg multiple testing corrections and we selected those genes with an average difference greater than 1.5 fold. A hierarchical clustering analysis was performed using pearson correlation with the separation ratio of 1.0 and minimum distance of 0.001 as similarity measure. Using a cardiovascular-specific gene array (CardioChip) of 42 heart failure (HF) patients from a wide range of etiology groups and 8 non-failing donors, we have identified down-regulation of LIM domain protein which may be an important pathway for the clinical progression of HF. We identified six genes, encoding LIM domain and Homer proteins, that are down-regulated in terminally failing hearts. The LIM and cysteine rich domain 1 (LMCD1) gene, in particular, was significantly down-regulated in all HF samples. This novel finding suggests that the LMCD 1 is a universal biomarker for end-stage HF. Other LIM domain genes were also down-regulated but only in non-familial dilated forms of cardiomyopathy. This is probably due to the fact that down-regulation of LIM protein expression may disrupt the cytoskeletal architecture, leading to dilated cardiomyopathy. In addition to identifying the LIM domain genes as possible regulatory genes involved in HF, we also demonstrated that the gene expression profile was able to classify multiple HF patients groups. This paper is the first to examine viral-induced cardiomyopathy, doxorubicin toxicity cardiomyopathy and perimartum cardiomyopathy and to perform the clustering analysis of those HF types providing new insights into human HF.
