In vitro cell cultures are frequently used to define the molecular background of drug resistance. In this study our major aim was to compare the gene expression signature of 2D and 3D cultured BRAFV600E mutant melanoma cell lines. We successfully developed BRAF-drug resistant cell lines from paired primary/metastatic melanoma cell lines in both 2D and 3D in vitro cultures. Using Affymetrix Human Gene 1.0 ST arrays, we determined the gene expression pattern of all cell lines. Our study highlights gene expression alterations that might help to understand the development of acquired resistance in melanoma cells in tumour tissue.

View SamplesMetastatic process is considered the predominant cause of melanoma-specific death, decreasing survival dramatically, and resulting in difficulties in the effective treatment. Large variety of molecular pathways associated with disease development and progression suggests that no individual molecular alteration is crucial in these processes per se.
