Dual drug targeting to kill colon cancers.

By combining a Wnt signaling inhibitor (pyrvinium phosphate) and a pro-survival inhibitor (ABT263) colon cancer cells can be killed. Combinations of Wnt signalling inhibitors with an inhibitor of the Bcl pro-survival protein family should be considered for the treatment of patients with precancerous colon adenomas or advanced colorectal cancers with APC mutations.
