Affymetrix Mouse Gene 2.0 ST Array (mogene20st)
Description
STAT2 is an essential transcription factor in type I interferon (IFN) signaling. STAT2 mediates the antigrowth and apoptotic effects of IFN as demonstrated in cell lines thus leading to the hypothesis that STAT2 has tumor suppressor function.

Description
In our studies we were searching for the new factors engaged in mitochondrial nucleic acids metabolism under stress conditions in humans. Quantitative proteomic approach revealed C6orf203 protein as a potential new factor engaged in response to perturbed mitochondrial gene expression. We showed that C6orf203 is a mitochondrial RNA binding protein which is able to rescue diminished mitochondrial transcription in stress conditions. Overall design: The dataset corresponds to RNAseq studies and comprises experiment performed in triplicate. The aim of this study was to examine the influence of C6orf203 silencing on mitochondrial transcriptome. To this end we engineered two stable cell lines with the use of human 293 Flp-In T-Rex cells as parental. First cell line inducible expressed miRNAs silencing endogenous copy of C6orf203 gene while second one expressed additionally transgenic version of FLAG-tagged C6orf203 which contained silent mutations causing insensitivity to miRNA. We also analyzed RNA isolated from parental 293 Flp-In T-Rex cells. RNAseq libraries were prepared with the use of strand-specific library preparation procedures. RNAs were random fragmented and reverse transcribed using random oligomers as primers (dUTP-based protocol, see PMID: 29590189, PMID: 22609201; this pipeline enables analysis of RNAs (> ~100 nucleotides)). RNA was isolated from unfractionated cells using TRI-Reagent. Before preparation of the libraries total RNA was subjected to depletion of nuclear-encoded rRNAs (Ribo-Zero rRNA Removal Kit (Human/Mouse/Rat), Epicenter). Libraries were sequenced with the help of Illumina sequencing platform.

Description
The concept of tumor stem cells (TSCs) provides a new paradigm for understanding tumor biology, although it remains unclear whether TSCs will prove to be a more robust model than traditional cancer cell lines. We demonstrate marked phenotypic and genotypic differences between primary human tumor-derived TSCs and their matched glioma cell lines. TSCs derived directly from primary glioblastomas harbor extensive similarities to normal NSC and recapitulate the genotype, gene expression patterns and in vivo biology of human glioblastomas. By contrast, the matched, traditionally grown tumor cell lines do not secondary to in vitro genomic alterations. These findings suggest that TSCs may be a more reliable model than many commonly utilized cancer cell lines for understanding the biology of primary human tumors. Analysis of gene expression data is described in Lee et al., Cancer Cell, 2006.
Publication Title
Tumor stem cells derived from glioblastomas cultured in bFGF and EGF more closely mirror the phenotype and genotype of primary tumors than do serum-cultured cell lines.

Description
Gliomas are mostly incurable secondary to their diffuse infiltrative nature. Thus, specific therapeutic targeting of invasive glioma cells is an attractive concept. As cells exit the tumor mass and infiltrate brain parenchyma, they closely interact with a changing micro-environmental landscape that sustains tumor cell invasion.
Publication Title
Identification of molecular pathways facilitating glioma cell invasion in situ.

Description
We analysed the effect of depriving the human cell of the catalytic activity of the nuclear 5' to 3' exoribonuclease XRN2. Catalytic amino acids in this protein had been defined previously, so it was possible to design a mutated catalytically inactive form of the protein (XRN2D233A-D235A) (PMID: 19194460). We created 293 Flp-In T-REx stable cell lines that induciby silence endogenous XRN2, and concomitantly express wild-type or inactive XRN2 in fusion with EGFP at the C-terminus. Thus, complementation of silencing of endogenous XRN2 with the expression of mutant version of the protein allows to directly link potential phenotypes with the lack of XRN2 enzymatic activity. To this end we isolated total RNA from tetracycline-treated cells, depleted it from rRNA and conducted strand-specific deep sequencing. Overall design: 6 samples were analysed. 3 replicates of control cells (endogenous copy of XRN2 gene is silenced and catalytically active exogenous XRN2-EGFP is expressed) and 3 replicates of cells deprived of XRN2 ribonucleolytic activity (endogenous copy of XRN2 gene is silenced and catalytically inactive exogenous XRN2(D233AD235A)-EGFP is expressed)
