               Sorcin is overexpressed in MD-resistant cancer cells, co-amplified with ABCB1, ABCB4 and other
               proteins involved in the resistance to chemotherapy in cancer cells. Sorcin overexpression induces
               resistance to many different chemotherapeutic drugs, while Sorcin silencing reverts drug resistance, by
               acting on many pathways.

               Sorcin is therefore an important MDR marker and may represent a therapeutic target for reversing MDR.
