The Non-Wnt Functions of APC: Unravelling the Link between APC and Apoptosis
… was combined with the Bcl-2 inhibitor, ABT-737. One possible explanation is the increase in Bcl-2 protein upon <i>Apc </i>depletion. However, I found that ABT-737, Taxol® and <i>Apc </i>depletion each cause activation of the unfolded protein response. This suggests that these treatments …
