Project description:Knockdown LRRK1-CAPT in NCI-H1299 lung cancer cell line by two independent siRNAs, to investigate the mechanism of LRRK1-CAPT in regulation of cell proliferation.
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.

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.
Project description:To investigate the tumor suppressor roleof CYB5R3 in lung cancer, we infected with adenoviral empty vector (EV) or CYB5R3 in NCI-H1299 cells.
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.
