Human A375 melanoma cell line treated with ciclopirox and crizotinib

To generate drug signatures in human A375 melanoma cell lines. A375 cell line was plated at 4 x 105 cells/mL overnight and treated with ciclopirox or crizotinib at 75% inhibitory concentrations (IC75, determined previously at 72h of treatment) or DMSO (vehicle) for 8h or 24h before harvest. To find out whether drug signatures generated in human melanoma cell lines are predictive of outcome in melanoma patients, we generated ciclopirox and crizotinib signatures in cell lines A375 . The expression of drug signatures were then tested by using GSSA (Gene Signature Survival Analysis) method to find out correlation with clinical outcome of melanoma patients.
