Title: Assessing the Combined Effect of Targeting ILK Signaling and Chemotherapy in Rhabdomyosarcoma

Abstract: The pediatric sarcoma alveolar rhabdomyosarcoma (ARMS) is highly aggressive with a poor prognosis for diagnosed patients. Here, we demonstrate that targeting the unique oncogene integrin-linked kinase (ILK) in ARMS cells in conjunction with the common chemotherapy agent vincristine, a synergistic effect is found in the reduction of cell viability in vitro. This result was achieved by both RNAi-mediated depletion of ILK and using a small molecule kinase inhibitor specific for ILK. Both techniques were found to disrupt important protein interactions at the site of the centrosome. Combination ILK disruption and vincristine treatment of cells induced the expression of apoptotic markers and arrested cells in the G2/M stage of the cell cycle. Interestingly, protein levels of JNK and its target c-Jun were regulated with combined treatment. Altogether, these findings indicate that the use of molecular targets like ILK may further improve the clinical treatment of ARMS.
