Five progressive sub-clones namely, CL1-1, CL1-2, CL1-3 CL1-4, and CL1-5 were selected using transwell and displayed increasing invasion potential (Chu et al, 1997). Here, we used microarrays to analyze and compare gene expression profiles between CL1-0 and CL1-5 for the identification of invasion/metastasis associated gene signatures. CL1-0 and CL1-5 lung cancer cell lines were used for RNA extraction and hybridization on Affymetrix microarrays. A total of 6 chips were used for microarray analysis including three biological repeats from CL1-0 and three biological repeats from CL1-5.", "source": "http://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-42407", "species": "human", "sample_source": "http://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-42407/samples/"}
