Expression profiling of Pkd1cko mice: A model of Polycystic Kidney Disease
Ontology highlight
ABSTRACT: Polycystic Kidney Disease (PKD) is a genetic disease of the kidney characterized by the gradual replacement of normal kidney parenchyma by fluid-filled cysts and fibrotic tissue. Autosomal Dominant Polycystic Kidney Disease (ADPKD) is caused by mutations in the PKD1 or PKD2 gene. Here we present an RNASeq experiment designed to investigate the effect of a kidney specific and Tamoxifen inducible knockout of the Pkd1 gene in mice. 7 mice were grouped into two groups, 4 Tamoxifen treated mice which develop an adult onset Polycystic Kidney Disease phenotype and 3 untreated mice which have WT phenotype.
Project description:Transcriptome analysis of two independent transgenic lines expressing a construct designed to suppress BdBAHD01. Analysis is intended to quantify suppression, check for off-target effects and look for pleiotropic effects.
Project description:RNA-seq analysis of two Testicular Germ Cell Cancers (TGCC) of patients with chemotherapy-resistant disease. Purpose of the study was to resolve the early development and progression of the disease by whole genome sequencing, RNA-seq and methylation profiling of the primary tumor, and the targeted sequencing of purified tumor components (embryonal carcinoma (EC), teratoma (TE), and yolk sac tumor (YST), precursor lesion (Germ Cell Neoplasia In Situ (GCNIS)), and metastases. Whole genome sequencing for the two patients, T6107 and T3209, have been deposited with the European Nucleotide Archive under project accession number PRJEB20644 / study accession ERP022815 ( http://www.ebi.ac.uk/ena/data/search?query=ERP022815 ).
Project description:We evaluated the role of Arkadia and ESRP2 in HEK293T cells Expression of mRNA in HEK293T cells under the knockdown of Arkadia or ESRP2
Project description:TTF-1/NKX2-1 was expressed by adenoviral vector and changes in gene expression were determined by RNA-sequencing. A549 cells were infected with Ad-TTF-1 or Ad-LacZ vectors and stimulated with TGF-beta for 24 hours or left untreated. Expression of polyA RNA was determined.
Project description:We identified RNA binding motif protein 47 (RBM47) as a target gene of transforming growth factor (TGF)-beta in mammary gland epithelial cells (NMuMG cells) that have undergone the epithelial-to-mesenchymal transition (EMT). TGF-beta repressed RBM47 expression in NMuMG cells and lung cancer cell lines. Expression of RBM47 correlated with good prognosis in patients with lung, breast, and gastric cancer. RBM47 suppressed the expression of cell metabolism-related genes, which were the direct targets of nuclear factor erythroid 2-related factor 2 (Nrf2; also known as NFE2L2). RBM47 bound to KEAP1 and Cullin3 mRNAs, and knockdown of RBM47 inhibited their protein expression, which led to enhanced binding of Nrf2 to target genomic regions. Knockdown of RBM47 also enhanced the expression of some Nrf2 activators, p21/CDKN1A and MafK induced by TGF-beta. Both mitochondrial respiration rates and the side population cells in lung cancer cells increased in the absence of RBM47. Our findings, together with the enhanced tumor formation and metastasis of xenografted mice by knockdown of the RBM47 expression, suggested tumor suppressive roles for RBM47 through the inhibition of Nrf2 activity. Effect of shRNA for RBM47 and TGF-beta on gene expression was evaluated by RNA-seq and RBM47-bound RNAs were identified by RIP-seq in A549 cells.
Project description:Changes in gene expression levels were identified by microarray. Samples were human kidney epithelial cell lines derived from patients with Autosomal Dominant Polycystic Kidney Disease (ADPKD) and unaffected controls. Autosomal Dominant Polycystic Kidney Disease (ADPKD), the most common inherited kidney disease, is due to mutations in PKD1 (85%) or PKD2 (15%) but has a highly variable phenotypic disease expression. We conducted parallel microarray profiling in normal and diseased human PKD1 cystic kidney cells to identify altered signatures of microRNA and mRNA target genes potentially implicated in disease expression.

The Pkd1cko mice were harvested at different time points 2-weeks, 3-weeks, 5-weeks, 10.5-weeks, 11-weeks and 15-weeks after gene inactivation.

Project description:We report the gene expression profiles by NGFR knockdown in H460 and H1299 cell lines and reveal that NGFR ablation activates p53 target gene expression. We examined gene expression in two different non-small-cell lung cancer cell lines, one with wild-type p53 and the other without p53.
Project description:The aim was to determine the changes in cell wall composition and transcriptome changes following treatment with the stress hormone precursor methyl jasmonate (MeJA) in the model grass Brachypodium distachyon. The correlation between transcript changes and cell wall composition changes allowed identification of candidate genes responsible for grass-specific features of the cell wall that are specifically changed in response to MeJA.
