Transcriptional profiles of TIMP-2 and Ala+TIMP-2 A549 overexpressing cells and in tumor xenografts.

Project description:TIMP-2 is an endogenous angiogenesis inhibitor, i.e. inhibits endothelial cell proliferation and tumor angiogenesis. As a result, TIMP-2 inhibits tumor growth and progression to metastasis. Understanding, therefore, the mechanisms of TIMP-2-mediated tumor growth inhibition would provide further support on the use of TIMP-2 as a novel biological agent for cancer therapy. We used microarray analysis to determine the TIMP-2 and Ala+TIMP-2 transcriptional profiles of A549 cancer cells in order to understand how TIMP-2 inhibits tumor growth and angiogenesis. We overexpressed TIMP-2 and its mutant (does not inhibit MMP) in A549 human lung cancer cells and determined TIMP-2 and Ala+TIMP-2 transcriptional profiles, groups of genes and associated biological functions. We then injected the cells in NOD-SCID mice and RNA from tumors were isolated for further analysis to identify genes that are associated with tumor growth inhibition.

Transcription profiling of human A549 lung cancer cells and their isogenic mitochondrial DNA (mtDNA)-depleted rho zero counterparts grown in cell culture and as tumor xenografts in immune-deficient mice.

Project description:Interactions between the gene products encoded by the mitochondrial and nuclear genomes play critical roles in normal eukaryotic cellular function. Here, we characterized the metabolic and transcriptional properties of A549 lung cancer cells and their isogenic mitochondrial DNA (mtDNA)-depleted rho zero counterparts grown in cell culture and as tumor xenografts in immune-deficient mice. A manuscript summarizing our conclusions is under review. Experiment Overall Design: A549 rho zero and their parental A549 cells were grown in culture and as xenografts in nude mice. All experiments conducted in culture were performed in triplicate (6 experiments total) and all experiments conducted in xenografts were performed in quadruplicate (8 experiments total). A manuscript summarizing our experimental design is under review.
