Therefore, we tested human cell lines derived from melanoma, HCC, and pancreas-CA for their nuclear NOTCH activity by EMSA and evaluated their sensitivity to the representative GSI DAPT and to the Aspergillum derived canonical NOTCH2/CSL transactivation inhibitor gliotoxin which efficiently induced apoptosis in CLL cells (Hubmann et al., 2013). The gene discussed is NOTCH2; the disease is melanoma.
