Combining Notch inhibition with current therapies for breast cancer treatment

Over recent years, there has been an increasing interest in targeting Notch signalling for the treatment of breast cancer. This has stemmed from the realization that many Notch pathway components display altered expression in breast cancer, and that Notch signalling impacts on many of the cellular properties associated with tumour initiation and progression. Consequently, Notch pathway inhibitors are now entering the initial stages of clinical trials. However, there is a definite need to consider how best to use these inhibitors and therefore which treatment strategies are likely to yield the most promising results. In particular, recent studies suggest that the greatest success will come from combining Notch pathway inhibitors with current breast cancer therapies.
