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:Time course data of normoxia- and hypoxia-treated prostate tumor cell lines (DU145, PC3, LNCaP, 22RV1) and primary prostate epithelial cells (four different donors) in three biological replicates.
Project description:Analysis and visualization of time-series transcriptomic data revealed Sudden TRanscriptomic Irregular Profile Expression changes (STRIPEs), characterized by anomalous transcript level values across the transcriptome in a given time point. We developed quantitative methods for detection and correction of STRIPEs in time-series. Correction of STRIPEs improves the quality of downstream analyses and reproducibility.Here we present cell-cycle transcriptomic time-series experiments containing STRIPEs from two different organisms/experimental conditions: Saccharomyces cerevisiae (BF264-15D background) in YEP 2% Dextrose at 38.5°C (mild chronic heat stress) and the K562 human cell line in RPMI + 10% BCS (bovine calf serum) + P/S.

Project description:This study investigated the differences in secreted proteins from cancer-associated fibroblasts (CAF) cultured under hypoxic and normoxic conditions. Culture supernatants from three CAF cell lines cultured under hypoxia and three CAF cell lines cultured under normoxia were analyzed by shotgun proteomics using LC-MS/MS to identify and quantify differentially expressed proteins.
Project description:The hypoxic tumor microenvironment is a critical driver of pancreatic ductal adenocarcinoma (PDAC) progression and chemoresistance. However, a comprehensive, multi-omics resource systematically profiling the molecular alterations induced by chronic hypoxia across diverse cellular components of PDAC is currently lacking. Here, we present a deeply characterized dataset generated from three PDAC cell lines, one pancreatic stellate cell line, and one normal pancreatic ductal epithelial cell line cultured under normoxic and chronic hypoxic (1% O₂) conditions. The dataset includes matched transcriptomic (RNA-Seq), proteomic, and phosphoproteomic profiles from biologically triplicated samples, all supported by phenotypic validation data confirming hypoxia-induced proliferation and gemcitabine resistance.
Project description:Purpose: To study differential mRNA and precursor miRNA expression under hypoxia exposure in cancer cells. We treated ovarian cancer cell line A2780 under hypoxia condition at different time points. Normoxi acultured cells at corresponding time point were used as controls.
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.
