“…Recent studies have clearly stated the crucial role of ABC transporters in cellular resistance to anticancer, anti-inflammatory and antiviral drugs [4]. Failure of chemotherapy on cancer cells is often linked to the expression and efflux activity of ABC transporters [3,5]. On the basis of the ability of ABC transporters to extrude xenobiotics outside the cell, nine of the known ABC transporter proteins were observed to be linked to multidrug resistance (MDR) phenotype.…”
