Cancer Cell article shows first evidence for targeting of Pol I as new approach to cancer therapy
Date:7/10/2012

The Cancer Cell publication highlighted a number of potential competitive advantages of CX-5461. An unanticipated finding was that malignant cells are considerably more dependent upon maintenance of high levels of Pol I activity than previously believed, and even modest inhibition of Pol I triggers cancer cell death. These results suggest that selective activation of a surveillance pathway to activate p53, using Pol I inhibitors such as CX-5641, is likely to be therapeutically useful in the treatment of a wide range of tumors. In addition, as a cancer-specific inducer of p53, CX-5461 was shown to be 300 times more potent than currently studied non-genotoxic p53 activators with alternate mechanisms.
