Constraint based modeling of
metabolism allows finding metabolic cancer hallmarks and
identifying personalized therapeutic windows

Abstract:
In order to choose optimal personalized anticancer
treatments, transcriptomic data should be analyzed within the
frame of biological networks. The best known human biological
network (in terms of the interactions between its different
components) is metabolism. Cancer cells have been known to have
specific metabolic features for a long time and currently there
is a growing interest in characterizing new cancer specific
metabolic hallmarks. In this article it is presented a method
to find personalized therapeutic windows using RNA-seq data and
Genome Scale Metabolic Models. This method is implemented in
the python library, pyTARG. Our predictions showed that the
most anticancer selective (affecting 27 out of 34 considered
cancer cell lines and only 1 out of 6 healthy mesenchymal stem
cell lines) single metabolic reactions are those involved in
cholesterol biosynthesis. Excluding cholesterol biosynthesis,
all the considered cell lines can be selectively affected by
targeting different combinations (from 1 to 5 reactions) of
only 18 metabolic reactions, which suggests that a small subset
of drugs or siRNAs combined in patient specific manners could
be at the core of metabolism based personalized treatments.

Project description:Inflammatory tissues are characterized by low oxigen concentrations (hypoxia). These conditions are very different from that usually present in tissue cultures where transcriptomic profiles of human fibroblasts from inflammatory tissues have been previously analysed. The aim of this study was to characterize the changes on gene expression induced by hypoxia in human synovial fibroblasts. We used microarray expression profiling in paired normoxic and hypoxic cultures of healthy and rheumatoid arthritis (RA) synovial fibroblasts (HSF and RASF). Hypoxia induces significant changes on the expression of large groups of genes in both HSF and RASF. The hypoxic and normoxic profiles are also different between both groups. These data demonstrate that hypoxia induces significant changes on gene expression in HSF and RASF and identify differences between RASF and HSF. Synovial fibroblasts obtained from 6 patients with rheumatoid arthritis (RASF) and 6 sex and age matched adult healthy donors (HSF) were used. SF cultures were incubated for 22 hours under normoxic or hypoxic (0.5% O2) conditions. Nine experiments per group were performed, single experiments with three SF lines, and duplicated in other three lines per group. All 18 normoxia-hypoxia experiments (36 microarray data) were used for paired analysis of the changes induced by hypoxia in HSF or RASF.

Project description:Expression profiling of 29 untreated breast cancer cell lines using Agilent 4x44K V1 (G4112F) dual color oligonucleotide microarrays The primary study objective was to establish a research resource for comparative transcriptomic analysis of a series of commercially available breast cancer cell lines representative of diverse histopathologic and molecular subtypes, generated on the Agilent oligonucleotide platform. A specific study objective was to perform a comparative transcriptional analysis of three cell lines established from a patient with triple negative metaplastic inflammatory breast cancer developed by Drs. Felding Habermann and Smider at the Scripps Research Institute, San Diego, CA. Cancer Res 2011;71(24 Suppl):Abstract nr PD03-07.

Project 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. Keywords: time course, gene expression, cell line, asbestos

Project description:To investigate the molecular mechanism that triggers endoplasmic reticulum (ER) stress-induced cellular senescence in breast cancer cells, we established MCF7 cell lines exposed to ATF6α ectopic expression. We then performed gene expression profiling analysis using data obtained from RNA-seq of 9 different cells at three time points.
