Project description:Objectives: The aim of this study was to investigate the prognostic significance of thirteen anticancer drug-relevant solute carrier transporters (SLCs) in pancreatic cancer in the context of clinical-pathological characteristics and the KRAS mutation status of tumors. Methods: Tumors and non-neoplastic pancreatic tissues were obtained from 32 histologically verified patients with pancreatic ductal adenocarcinoma. The transcript profile of SLCs was assessed using quantitative real-time PCR. KRAS mutations in exon 2 were assessed by high resolution melting analysis and confirmed by sequencing. Results: SLC22A3 was upregulated and SLC22A1, SLC22A2, SLC22A11, SLC28A1, SLC28A3 and SLC29A1 were downregulated when compared with non-neoplastic pancreatic tissues. Moreover, significantly lower levels of SLC22A1, SLC22A11 and SLC29A1 were found in tumors with angioinvasion. There was also a significantly higher transcript level of SLC28A1 in tumors with regional lymph nodes affected by metastasis. The study found that a high expression of SLC22A1 or SLC28A1was significantly associated with poor overall survival in unselected patients. In contrast, a high expression of SLC22A3 or SLC29A3 was significantly associated with longer overall survival in patients treated with nucleoside analogs. Finally, SLC levels were not found to be associated with KRAS mutation status in exon 2. Conclusions: This study identified a number of associations of SLCs with prognosis of pancreatic cancer patients. Transcript levels of thirteen anticancer drug-relevant solute carrier transporters (SLCs) were determined by qPCR in pancreatic ductal adenocarcinomas and non-neoplastic tissue samples from 32 pancreatic cancer patients. MRPL19, ELF1 and POLR2A were used as reference genes for data normalization.

Project description:To investigate whether BRD4-chromatin binding is modulated by purine levels, we performed BRD4 ChIP-seq in cells with SLC nucleoside transporters knockout, or cells with de novo purine synthesis inhibitor 6-MP treatment. (+)-JQ1, an inhibitor which disrupts BRD4 and acetylated histone binding, was used as a positive control.

Project description:The series were performed to study the changes in gene expression upon diploidization of KBM7 cancer (CML) cell line. The line can exist either as a clone with 24 chromosomes (nearly haploid) or with 48 chromosomes (nearly diploid). Gene expression patterns are largely ploidy-independent, as suggested by this experiment Single cell derived clones of KBM7 cell line were grown. Included 7 haploid and 10 diploid clones, each with 2 independent total RNA extraction/microarray run. Also included peripheral blood mononuclear cells (PBMC) samples for comparison purposes.

Project description:Many thousand long non-coding (lnc) RNAs are mapped in the human genome. Time consuming studies using reverse genetic approaches by post-transcriptional knock-down or genetic modification of the locus demonstrated diverse biological functions for a few of these transcripts. The Human Gene Trap Mutant Collection in haploid KBM7 cells is a ready-to-use tool for studying protein-coding gene function. As lncRNAs show remarkable differences in RNA biology compared to protein-coding genes, it is unclear if this gene trap collection is useful for functional analysis of lncRNAs. Here we use the uncharacterized LOC100288798 lncRNA as a model to answer this question. Using public RNA-seq data we show that LOC100288798 is ubiquitously expressed, but inefficiently spliced. The minor spliced LOC100288798 isoforms are exported to the cytoplasm, whereas the major unspliced isoform is nuclear localized. This shows that LOC100288798 RNA biology differs markedly from typical mRNAs. De novo assembly from RNA-seq data suggests that LOC100288798 extends 289kb beyond its annotated 3' end and overlaps the downstream SLC38A4 gene. Three cell lines with independent gene trap insertions in LOC100288798 were available from the KBM7 gene trap collection. RT-qPCR and RNA-seq confirmed successful lncRNA truncation and its extended length. Expression analysis from RNA-seq data shows significant deregulation of 41 protein-coding genes upon LOC100288798 truncation. Our data shows that gene trap collections in human haploid cell lines are useful tools to study lncRNAs, and identifies the previously uncharacterized LOC100288798 as a potential gene regulator. We cultured and processed 8 KBM7 cell lines in one batch. These cell lines were: two wild type KBM7 cells (WT2 and WT3), two monoclonal KBM7 cell lines with gene trap cassette insertions outside of the body of LOC100288798 (C1 and C2), two independently obtained KBM7 clones with gene trap cassette insertion 3kb downstream LOC100288798 transcriptional start site (TSS) (3kb1 and 3kb2), one independently obtained KBM7 clone with gene trap cassette insertion 100kb downstream LOC100288798 TSS replicated twice at the thawing step (100kb1 and 100kb2). We isolated total RNA from all th 8 cell lines, applied DNAseI treatment and ribosomal RNA depletion, and thhen prepared strand-specific RNA-seq libraries, which were pooled in equal molarities and sequenced using Illumina HiSeq 2000 (8 pooled samples were sequence on 2 lanes). We performed 50bp single-end RNA-seq. We used these 8 samples (4 untreated: WT2, WT3, C1, C2 and 4 treated:3kb1, 3kb2, 100kbk1, 100kb2) to analyze genome-wide gene deregulation associated with LOC100288798 lncRNA truncation

Project description:Transcriptional response of KBM7 cells to IFN-gamma or TNF-alpha was investigated in control or cells with genetrap insertions in JAK2 or TNFRS1A, respectively. The experiment shows that, as expected, cells lacking JAK2 or TNFRS1A expression display a severly blunted response to the tested cytokines. KBM7 genetrap mutant cells stimulated with TNF-alpha and IFN-gamma Sample WT_1 corresponds with the control sample for the IFN-gamma stimulation; Sample WT_2 corresponds with the control sample for the TNF-alpha stimulation. As the expected differences between the samples was large, only single replicates were performed for each condition
