Transcription profiling of human embryonic kidney cells HEK293 overexpressing the transcription factors HNF4a2 or mutant forms HNF4a2 C106R and HNF4a2 R154X to identify HNF4a regulated genes in kidney cells being several of these genes deregulated in renal cell carcinoma

ABSTRACT: Analysis of gene expression in human embryonic kidney cells HEK293 overexpressing the transcription factors HNF4a2 or mutant forms HNF4a2 C106R and HNF4a2 R154X, which were introduced by FRT/FLP recombination. The analysis was performed 24 hours following 1sg/ml tetracycline treatment to induce the expression of the genes. Results identify HNF4a regulated genes in kidney cells being several of these genes deregulated in renal cell carcinoma.

Hepatocyte nuclear factor 4alpha (HNF4alpha) is a tissue-specific transcription factor known to regulate a large number of genes in hepatocytes and pancreatic beta cells. Although HNF4alpha is highly expressed in some sections of the kidney, little is known about its role in this organ and about HNF4alpha-regulated genes in the kidney cells. The abundance and activity of HNF4alpha are frequently reduced in renal cell carcinoma (RCC) indicating some tumor suppressing function of HNF4alpha in rena ...[more]

Transcription profiling of human macrophages and dendritic cells exposed to phylogenetically distinct parasites

Project description:Monocyte-derived dendritic cells (DC) and macrophages (MÎ¦) generated in vitro from the same individual blood donors were exposed to five different pathogens, and gene expression profiles were assessed by microarray analysis. Responses to Mycobacterium tuberculosis and to phylogenetically distinct protozoan (Leishmania major, L. donovani, Toxoplasma gondii) and helminth (Brugia malayi) parasites were examined, each of which produces chronic infections in humans yet vary considerably in the nature of the immune responses they trigger.

Transcription profiling of mouse KO Clcn5-/- model for Dents disease in kidney, bone and intestine

Project description:Mutations in ClC-5 cause Dent's disease, a disorder associated with low molecular weight proteinuria, hyperphosphaturia and kidney stones. ClC-5 is a Cl /H+-exchanger predominantly expressed in the kidney, where it facilitates the acidification of proximal tubular endosomes. The reduction in proximal tubular endocytosis resulting from a lack of ClC-5 raises the luminal concentration of filtered proteins and peptides like PTH. We used gene expression profiling to identify possible signaling pathways that might be changed in ClC-5 KO kidneys, bones and intestines.<br%gt; Mouse model described in Piwon et al, ClC-5 Cl--channel disruption impairs endocytosis in a mouse model for Dent's disease, Nature 408, 369-373 (16 November 2000),doi: 10.1038/35042597

TGFß1-driven epithelial to mesenchymal transition in human kidney cell line

Project description:TGFbeta is the major cytokine driver of fibrosis in the kidney and other tissue. Epithelial-mesenchymal transition has been postulated to contibrute to renal fibrosis in diseases such as diabetic nephropathy. We wished to identify novel genes that were upregulated in human kidney epithelial cells in response to TGFb1.The transcriptional responses for human proximal tubule epithelial cells to 10 ng/ml TGFbeta1 was examined over 24 and 48 hr There were three treatment groups: vehicle, 24hr TGFb1, 48 hr TGFb1. Each treatment was carried out in triplicate 10 cm plates and the experiment was carried out in triplicate using consecutive passages of cells.

Transcription profiling time series of human skeletal muscle samples from metabolic syndrome patients following defined exercise (STRRIDE study)

Project description:STRRIDE is an exercise intervention study of different doses and intensities in overweight women and men with the metabolic syndrome. We profiled biopsies from 3 female and 3 male STRRIDE subjects in the âhighâ exercise group (2,200 kCal/wk). Muscle biopsies were profiled at entry (0h), and after 9 months of aerobic training (24 hrs post-last bout, 96 hrs post last bout, and 336h (14 days) de-training). Included also are pilot expression data from 3 male subjects. Note that files GSM19162.txt and GSM20659.txt as downloaded from GEO are identical.

Transcription profiling of rat heart samples from animals with physiological or pathological cardiac hypertrophy

Project description:Dahl salt-sensitive (DS) rats were obtained from Harlan Sprague Dawley Laboratory at 5 weeks of age. At 6 weeks of age, physiologic cardiac hypertrophy was generated by a; vigorous daily exercise regimen for 6 weeks (e group). The exercise protocol is based on those described previously with modifications (Wisloff U et al., 2001; Jin H et al., 1994). Rats were exercised daily for 6 weeks on a rodent treadmill (Exer-6M; Columbus Instruments). The exercise program consisted of three weeks of progressively strenuous exercise regimens; followed by three weeks of maintenance period, during which the rats were exercised at 16 m/min at a 5o incline for 90 minutes/day. All rats completed the exercise protocol. Pathological cardiac hypertrophy was generated by feeding a 6% NaCl diet to DS rats at 6 weeks of age (h group) (Inoko M et al., 1994). Control rats (c group) were age matched and sedentary DS rats fed normal rat chow.

Nanoceria modulates kidney bean proteomic response and compromises its seed quality

Project description:There is inadequate understanding of the environmental fate and effects of engineered nanoparticles, including nanoceria. Also, knowledge about the influence of environmental factors on the bioavailability of these particles and resulting impacts on the nutritional quality of crops is limited. Alterations in mineral and macromolecular composition of some grains and fruits under nanoceria exposure have been reported recently; however, the cellular mechanisms associated with the effects are unknown. Here, we show that the impact of nanoceria at 62.5 to 500 mg/kg soil on kidney bean (Phaseolus vulgaris) productivity and seed quality are influenced by soil organic matter content. Seeds obtained from plants exposed to nanoceria at 125 mg/kg showed unique and contrasting response in terms of nutritional quality under varying soil organic matter content. Additionally, quantitative proteomic analysis provides evidence for dose-dependent down-regulation of some major proteins associated with nutrient storage and carbohydrate metabolism, including phaseolin and lectins in the exposed seeds. This study suggests that nCeO2 exposure negatively impacts the nutritional quality of kidney beans. This altered seed quality may have significant implications for food production and human health.

Transcription profiling of embryonic kidneys from wild type and Hoxa11, Hoxd11 compound null mice throughout development to characterize Hoxa11/Hoxd11 mutant kidney development

Project description:Complete (whole) embryonic kidneys were dissected from wild type and Hoxa11, Hoxd11 compound null embryos throughout development. Targets from two biological replicates of each were generated and the expression profiles were determined using Affymetrix MOE430A and MOE430B arrays. Comparisons between normal and mutant and comparisons of development samples identified global patterns of gene regulation in kidney development Experiment Overall Design: Embryonic metanephric kidney samples throughout development were analyzed based on normalization to adult kidney samples. In addition, Hoxa11, Hoxd11 compound null embronic kidneys were normalized to wild type embryonic controls. All developmental and adult stages were represented in biological (seperate embryo/animal replicate). Normalized data files were not included because there appears to be a mismatch between the composite sequence identifiers in some of them and the array design selected.
