COMPOSITIONS AND METHODS FOR TREATING CANCER USING COMPOSITIONS COMPRISING AN INHIBITOR OF ENDOTHELIN RECEPTOR ACTIVITY

摘要

Elevated ETRB activity, BCL-2A1 activity and/or PARP-3 activity was detected in cancer cells, and determined to be associated with growth and proliferation of the cancer cells. Accordingly, methods are provided for treating cancer by reducing or inhibiting the ETRB activity, BCL-2A1 activity and/or PARP-3 activity. Also provided are methods of determining the responsiveness of cancer cells to treatment with inhibitors of ETRB activity, BCL-2A1 activity and/or PARP-3 activity. Further, decreased cell viability was observed to correlate with reduction in ETRB expression, and reduction in ETRB protein levels by siRNA led to an increase in cell death.
