[BioC] DESeq analysis of resistance data

I am analysing RNASeq data from cancer cell lines.  I have 3 groups with n=5 in each group.  One group is sensitive to a drug, the second group has been selected for clones which have become resistant to the drug.  The third group is a control, vehicle-treated group.  I have used DESeq2 before to compare two groups but I'd be interested in advice on how to analyse these data please.  I am interested in identifying differential changes in the resistant group which might be leading to the acquired resistance.  Would analysing these data using an ANOVA model be appropriate?
