Project description:H69M cells derive from H69 small cell lung cancer cells subjected to prolonged treatment with HGF. Among the whole population of cells, a subset of more fibroblastic cells was isolated (H69M-mesenchymal). In this experiment we compared expression profiles of both cell lines Keywords: Expression Profiling by array We analyzed 3 arrays from each condition:H69 versus H69M SCLC cell lines

Project description:In cells derived from a genetically engineered Rb1 and Trp53 loss mouse model of SCLC (RP) expression of one of the three MYC family members induced from the endogenous locus using CRISPR activation. Cells were first stably transfected with the lenti-MS2-p65-HSF1 activator plasmid. Respective sgRNAs targeting either Myc, Mycl or MYCN were then cloned into the lentiSAMv2 system and transfected separately into the MS2-p65-HSF1 cells using lentiviral delivery.

Project description:Insulin-like growth factor receptor-1 (IGF-1R) inhibition could be a relevant therapeutic approach in small cell lung cancer (SCLC) given the importance of an IGF-1R autocrine loop and its role in DNA damage repair processes. We assessed IGF-1R and pAkt protein expression in 83 SCLC human specimens. The efficacy of R1507 (a monoclonal antibody directed against IGF-1R) alone or combined with cisplatin or ionizing radiation (IR) was evaluated in H69, H146 and H526 cells in vitro and in vivo. Innovative genomic and functional approaches were conducted to analyze the molecular behavior under the different treatment conditions. A total of 53% and 37% of human specimens expressed IGF-1R and pAkt, respectively. R1507 demonstrated single agent activity in H146 and H526 cells but not in H69 cells. R1507 exhibited synergistic effects with both Cisplatin and IR in vitro. The triple combination R1507-Cisplatin-IR led to a dramatic delay in tumor growth compared to Cisplatin-IR in H526 cells. Analyzing the apparent absence of antitumoral effect of R1507 alone in vivo, we observed a transient reduction of IGF-1R staining intensity in vivo, concomitant to the activation of multiple cell surface receptors and intracellular proteins involved in proliferation, angiogenesis and survival. Finally, we identified that the nucleotide excision repair pathway (NER) was mediated after exposure to R1507-CDDP and R1507-IR in vitro and in vivo. In conclusion, adding R1507 to the current standard Cisplatin-IR doublet reveals remarkable chemo- and radiosensitizing effects in selected SCLC models and warrants to be investigated in the clinical setting. We used microarrays to investigate the effect of IGF-1R targetting on the global gene expression.

We used microarrays to investigate the effect of IGF-1R targetting on the global gene expression. Gene expression data from H526 xenografts under various treatment and time conditions Total mRNA from 33 NCI-H526 SCLC (small-cell lung cancer) xenografts was hybridized to Affymetrix HGU133 Plus 2.0 expression arrays. Log2 gene expression values were calculated using RMA. (A) To identify the molecular mechanisms involved in the response to R1507 alone along the treatment time, we performed global gene expression profiling in H526 xenografts at the following time points: baseline (vehicle), R1507 day 1 and R1507 day 7. (B) To identify the molecular mechanisms involved in the response to CDDP- and IR-R1507 combinations, we performed global gene expression profiling on mice bearing H526 xenografts treated with the following treatment conditions: vehicle, R1507 CDDP, IR, CDDP-R1507 and IR-R1507.

Project description:Aim: To determine the miRNA expression profile of SCLC cell lines vs. normal lung tissue. Keywords: disease state analysis Total RNA isolated from SCLC cell lines H69, HTB-172, HTB-173 and HTB-184 were compared to a mixed RNA sample derived from 6 normal lung tissue samples (fresh surgical material), from 6 tumor-free patients. The same reference sample (normal lung) was used on all 4 microarrays.

Project description:The response of tumors to PDT treatment is expected to provide information on effects of oxygen depletion, induced apoptosis, induction of an inflammatory response and induction of an ani-tumor immune response. Experiment Overall Design: NCI-H69 human SCLC xenografts were induced in SCID mice. Three pairs of xenograft tumors, PDT treated and untreated controls, were harvested four hours after PDT treatment. RNA was isolated and prepared for hybridization to human Affymetrix GeneChip arrays.
