Transcriptomic differences between OVCAR3 and SKOV3 and PCA after interaction with the mesenchymal cells. A. Ingenuity pathway analysis network obtained when the differentially regulated genes genes between SKOV3 and OVCAR3 were overlaid on the gene list related to mesenchymal phenotype. Genes in green are over-expressed by at least 5 fold in SKOV3, genes in red are over-expressed in OVCAR3 (by at least 5 folds). B. PCA analysis for the ovarian cancer cells lines alone or post-contact with the Mesenchymal cells.
