The molecular profiling of drug-sensitive and drug-resistant cells may be helpful to clarify if altered expression of miRNAs can contribute to the drug-resistant phenotype. The expression pattern of miRNAs of three ovarian carcinoma cell lines was examined. The analysis revealed the modulation of several miRNAs in the two platinum-resistant cell lines as compared to parental platinum-sensitive cells. The integration of the information obtained through miRNA expression analysis may be useful to clarify the specific molecular alterations of factors and pathway favouring survival of tumor cells.
