Description
Asbestos has been shown to cause chromosomal damage and DNA aberrations. The fiber is associated with many different lung diseases such as asbestosis, malignant mesothelioma, and lung cancer, but the disease-related processes are still largely unknown. Our aim was to identify specific gene expression profiles by using Affymetrix arrays, in human cell lines A549, Beas-2B, and MeT5A exposed to asbestos in a time-dependent manner. The hybridization data was analyzed using an algorithm specifically designed for clustering short time series expression data, a canonical correlation analysis (CCA) for identifying correlations between the cell lines, and a Gene Ontology (GO) analysis method for the identification of enriched differentially expressed biological processes.

Description
Progressive myoclonus epilepsy of Unverricht-Lundborg type (EPM1) is an inherited neurodegenerative disease with myoclonus, seizures and ataxia, caused by the mutations in cystatin B (CSTB) gene. In an approach towards understanding the molecular basis of pathogenic events in EPM1 we have utilized the cystatin B deficient mice (Cstb-/-), a model for the disease. We have characterized the gene expression changes from the cerebellum of Cstb-/- mouse at postnatal day 7 (P7) and P30 as well as in cultured cerebellar granule cells using a pathway-based approach. A marked upregulation of immune response genes was seen at P30, reflecting the ongoing neuropathology, however, the observed alterations in complement cascade genes could also imply defects in synaptic plasticity. Differentially expressed genes in pre-symptomatic Cstb-/- animals at P7 were connected to synaptic function and plasticity and in cultured cerebellar granule cells to cellular biogenesis, cytoskeleton and intracellular transport. Especially GABAergic pathways were affected.

Description
Mutations in the genes encoding isocitrate dehydrogenase 1 and 2 (IDH1/2) occur in a variety of tumor types, resulting in production of the proposed oncometabolite, 2-hydroxyglutarate (2-HG). How mutant IDH and 2-HG alter signaling pathways to promote cancer, though, remains unclear. Additionally, there exist relatively few cell lines with IDH mutations. To examine the effect of endogenous IDH mutations and 2-HG, we created a panel of isogenic epithelial cell lines with either wild-type IDH1/2 or clinically relevant IDH1/2 mutations. Differences were noted in the ability of IDH mutations to cause robust 2-HG accumulation. IDH1/2 mutants that produce high levels of 2-HG cause an epithelial-mesenchymal transition (EMT)-like phenotype, characterized by changes in EMT-related gene expression and cellular morphology. 2-HG is sufficient to recapitulate aspects of this phenotype in the absence of an IDH mutation. In the cells types examined, mutant IDH-induced EMT is dependent on upregulation of the transcription factor ZEB1 and downregulation of the mir-200 family of microRNAs. Furthermore, sustained knockdown of IDH1 in IDH1 R132H mutant cells is sufficient to reverse many characteristics of EMT, demonstrating that continued expression of mutant IDH is required to maintain this phenotype. These results suggest mutant IDH proteins can reversibly deregulate discrete signaling pathways that contribute to tumorigenesis

Description
A transgenic TMPRSS2:ERG mouse model was engineered in FVB background and compared to its wildtype counterpart in the absence of any treatment This experiment is designed to look at ERG-dependent changes in phenotype and gene expression Overall design: A loxP-GFP-loxP-hERG exon 4-11 cassette was inserted into a BAC clone containing the TMPRSS2 locus using a recombineering kit. This modified BAC was used for pronuclear injection and generation of germline-transmitting mice. One line expressing high GFP was used for pronuclear injection of Cre protein and one sub-line that transmitted the TMPRSS2:ERG transgene into the germline was subsequently bred to homozygosity.
