Expression data for cultured NCI-H1299 parental and spheroid cells as well as their derived xenograft models

ABSTRACT: Current approaches to the preclinical investigation for novel cancer therapies rely heavily on the use of traditional cancer cell lines maintained in serum-containing conditions. The discrepancy between promising preclinical efficacy and clinical outcome of most novel anticancer agents emphasizes a need for developing predictive preclinical models that preserve the integrity of original patient tumors, including cancer stem cell (CSC) compartment. In this study, we isolate and characterize CSCs from a non-small cell lung cancer cell line, NCI-H1299, by selectively propagating the cells in a stem-cell culture condition. Isolated CSCs proliferated as nonadherent spheroids, displayed capacity to differentiate and self-renew and exhibited higher tumorigenic potential compared to the parental cells. The gene expression profiles of NCI-H1299 parental cells (serum-containing medium), CSCs (stem-cell medium), and xenograft tumor derived from both cell types were studied by Affymetrix array analysis

Lentiviral shRNA knockdown of PTK7 in lung adenocarcinoma cell lines NCI-H1299 and NCI-H2009

Project description:PTK7 was identified from a meta-analysis of 1905 non-small-cell lung cancer (NSCLC) samples across 12 datasets to be one of seven genes commonly up-regulated in lung adenocarcinoma (ADC). Using ADC cell lines NCI-H1299 and NCI-H2009, disruption of PTK7 resulted in decreased cell viability and induction of apoptosis. A xenotransplantation model of the cell lines with PTK7 knock-down also resulted in decreased tumor burden. We assayed gene expression in these cell lines after PTK7 knock-down by shRNA to uncover deregulated pathways and genes. 8 samples were analyzed. In each cell line, we knocked down PTK7 with 2 independent hairpins, and 2 control hairpins targeting luciferase and GFP. Thus, NCI-H1299 has 2 samples of PTK7 knock-down, and 2 samples of control knock down. NCI-H2009 has similar samples.

NCI-H1299 cell line transfected with human DENND2D and vector

Project description:Gene expression for NCI-H1299 cell line transfected with human DENND2D and vector (pcDNA3.1/V5-His TOPO TA vector) respectively. The microarray experiment was designed to perform four replicates for each H1299-DENND2D and H1299-vector sample. cRNA used in replication 1 and 2 was from the same label reaction to perform the hybridization replicates.

NCI-H1299 lung cancer cell line transfected with miR-34a and ghR-34a

Project description:Analysis NCI-H1299 lung cancer cells transfected with synthetic oligo mimics for microRNAs (miRNAs) miR-34a and ghR-34a. We developed a 30-nucleotide single-strand RNA (ssRNA), termed “guide hairpin RNA (ghR),” that has a physiological function similar to that of miRNA and siRNA. The ghR caused no innate cytokine response either in vitro or in vivo. In addition, its structure does not contain a passenger strand seed sequence, reducing the potential for off-target effects relative to existing short RNA reagents. Systemic injection of ghR-form miR-34a (ghR-34a) suppressed tumor growth in a mouse model of RAS-induced lung cancer. Furthermore, ghR-34a functioned in a Dicer- and Ago2-independent manner. This novel RNAi technology may provide a novel, safe, and effective nucleic acid drug platform that will increase the clinical usefulness of nucleic acid therapy. MiR-34a–targeted mRNAs regulated by mRNA degradation rather than translational inhibition were identified using microarray data from miR-34 and ghR-34a transfectants.

PNAs-A15 effects on non-small cell lung cancer cell line

Project description:Expression profile of parental wild type non-small cell lung cancer, NCI-H460, and cancer stem cell-rich (CSC-rich) populations treated with PNAs-A15 for 6 h. Results provide the information that PNAs-A15, a peptide nucleic acid of A-repeats length 15 bp, suppressed up-regulated A-repeats containing genes in both parental wild type and CSC-rich cells. In this study, we isolate cancer stem cell-rich (CSC-rich) population from a non-small cell lung cancer (NSCLC) cell line, NCI-H460, by selectively propagating the cells in a spheroid culture condition. The parental wild type H460 and CSC-rich cells were maintained at 37Â°C in 5% CO2 under sterile conditions in Roswell Park Memorial Institute (RPMI) 1640 medium. Cells were treated with PNAs-A15 in 6-well microplates for 6 h. Total RNA was isolated and hybridized on the HumanHT-12 v4 Expression BeadChip. The RNA expressions were evaluated.

Expression data from NCI-H1299 and NCI-H1299/CDDP cells

Project description:Non-small cell lung cancer (NSCLC) patients are prone to drug resistance during chemotherapy. Therefore, in order to compare the changes in the gene expression profiles of NSCLC cells before and after drug resistance, we constructed cisplatin-resistant cells (NCI-H1299/CDDP), and compared the gene expression profiles with those of the parental NCI-H1299 cells. We used microarrays to study in detail the global gene expression changes before and after drug resistance in NSCLC cells and identified genes that were up- or down-regulated during this process.

H1299 cells: p53 transcriptional response in hypoxia

Project description:Transcriptional profiling of H1299 non-small cell lung carcinoma cells transfected with either wt p53 or mut(175) p53 driven by the 5xHRE promoter (5 repeats of hypoxia-inducible factor response elements) and treated for 16 h with normoxia (21% O2) or hypoxia(<0.1% O2). 5xHRE promoter ensures that p53 expression is induced in hypoxic conditions only. Goal was to determine the transcriptional response of p53 in hypoxia and the 175 p53 mutant was used as a control as it is DNA-binding defective and transcription-incompetent mutant. Four-condition experiment: wt p53-transfected H1299 cells treated with normoxia, mut p53-transfected H1299 cells treated with normoxia, wt p53-transfected H1299 cells treated with hypoxia, mut p53-transfected H1299 cells treated with hypoxia. Biological replicates: 1 normoxic sample with wt p53, 1 normoxic sample with mut p53, 3 hypoxic samples with wt p53, 3 hypoxic samples with mut p53.

Evaluation of NCI-7 Cell Line Panel

Project description:Reference materials are vital to benchmarking the reproducibility of clinical tests and essential for monitoring laboratory performance for clinical proteomics. The reference material utilized for mass spectrometric analysis of the human proteome would ideally contain enough proteins to be suitably representative of the human proteome, as well as exhibit a stable protein composition in different batches of sample regeneration. Previously, The Clinical Proteomic Tumor Analysis Consortium (CPTAC) utilized PDX-derived comparative reference (CompRef) materials for the longitudinal assessment of proteomic performance, however, inherent drawbacks of PDX-derived material has resulted in efforts to identify a new source of CompRef material. In this study, we examined the utility of using a panel of seven cancer cell lines, NCI-7 Cell Line Panel, as a reference material for mass spectrometric analysis of the human proteome. Our results showed that not only is the NCI-7 material suitable for benchmarking laboratory sample preparation methods, but NCI-7 sample generation is highly reproducible at both the global and phosphoprotein levels. In addition, the predicted genomic and experimental coverage of the NCI-7 proteome suggests the NCI-7 material may also have applications as a universal standard proteomic reference.
