MiRNA expression profile of SCLC cell lines vs. normal lung

ABSTRACT: 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.

Human lung cancer cell lines DMS-273 (SCLC) and NCI-H1437 (NSCLC): scrambled vs. shRNA clones

Project description:Transcriptional profiling of two human lung cancer cell lines, DMS-273 (small cell lung cancer) and NCI-H1437 (non-small cell lung cancer), stably transfected either with innocuous scrambled shRNAs or SETDB1-specific.The objective was to identify global gene expression changes due to the depletion of the H3K9me3 methyltransferase SETDB1. 3 replicates for DMS-273 and 1 Control; 2 replicates for NCI-H1437 and 1 Control

Hodgkin lymphoma cell lines are characterized by a specific miRNA expression profile.

Project description:Hodgkin lymphoma (HL) is derived from preapoptotic germinal center B cells, although a general loss of B cell phenotype is noted. Using quantitative reverse transcription-polymerase chain reaction and miRNA microarray, we determined the microRNA (miRNA) profile of HL and compared this with the profile of a panel of B-cell non-Hodgkin lymphomas. The two methods showed a strong correlation for the detection of miRNA expression levels. The HL-specific miRNA included miR-17-92 cluster members, miR-16, miR-21, miR-24, and miR-155. Using a large panel of cell lines, we found differential expression between HL and other B-cell lymphoma-derived cell lines for 27 miRNA. A significant down-regulation in HL compared to non-Hodgkin lymphoma was observed only for miR-150. Next, we performed target gene validation of predicted target genes for miR-155, which is highly expressed in HL and is differentially expressed between HL and Burkitt lymphoma. Using luciferase reporter assays, we validated 11 predicted miR-155 target genes in three different HL cell lines. We demonstrated that AGTR1, FGF7, ZNF537, ZIC3, and IKBKE are true miR-155 target genes in HL.

miRNA profile of radioresistant pancreatic cancer cell lines

Project description:We established radioresistant cell sublines, named as BxPC3/RR1 and BxPC3/RR2 which were derived from parental human pancreatic cancer cell line BxPC3. The miRNA expression profiles of the radioresistant pancreatic cancer cells were then compared with their parental cells. Three samples were analysed. miRNAs that were differentially expressed (increased or decreased in expression by ≥1.5-fold) between the radioresistant and parental cells were identified.

Alterations in exosomal miRNA profile upon epithelial-mesenchymal transition in human lung cancer cell lines.

Project description:BackgroundEpithelial-mesenchymal transition (EMT) is regarded as a critical event during tumor metastasis. Recent studies have revealed changes and the contributions of proteins in/on exosomes during EMT. Besides proteins, microRNA (miRNA) is another important functional component of exosomes. We hypothesized that the miRNA profile of exosomes may change following EMT and these exosomal miRNAs may in return promote EMT, migration and invasion of cancer cells.ResultsThe small RNA profile of exosomes was altered following EMT. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis revealed that the specific miRNAs of M-exosomes have the potential to drive signal transduction networks in EMT and cancer progression. Co-culture experiments confirmed that M-exosomes can enter epithelial cells and promote migration, invasion and expression of mesenchymal markers in the recipient cells.ConclusionOur results reveal changes in the function and miRNA profile of exosomes upon EMT. M-exosomes can promote transfer of the malignant (mesenchymal) phenotype to epithelial recipient cells. Further, the miRNAs specifically expressed in M-exosomes are associated with EMT and metastasis, and may serve as new biomarkers for EMT-like processes in lung cancer.

Gene expression from H69M versus H69 SCLC cell lines

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

Normal vs. Tumor Prostate miRNA

Project description:Comparison of miRNA expression profiles in a small set of prostate needle core biopsies or fine needle aspirates. Keywords: Expression profiling of prostate needle core biopsies MicroRNA expression was compared between a pooled normal sample consisting of 10 separate normal adjacent to tumor prostate needle core biopsies, two prostate tumor cell lines (PC3 and LNCaP), two needle core biopsies, and a fine needle aspirate of a prostate tumor metastasis to the supraclavicular lymph node. MicroRNA was isolated from fresh frozen tissue sections of the needle core biopsies using the mirVana miRNA Isolation kit from Ambion per the manufacturer's instructions. MicroRNA was amplified using 10 ng input and 750 ng of amplified material was subsequently labeled for hybridization. All samples were normalized to the same normal prostate control.

Gene expression of samples derived from normal lung and patients with small cell lung cancer (SCLC) or non-small cell lung cancer (NSCLC)

Project description:Differences in gene expression profiles regarding the expression of genes encoding for proteins with G protein-coupled receptor (GPCR) activity between SCLC and NSCLC and normal lung samples was successfully examined. In the present study, 8 SCLC, 16 NSCLC and 14 normal lung RNA samples (human) had been purchased from OriGene Technologies. Gene expression analysis was performed using Affymetrix microarrays (Human Exon 1.0 ST Array).
