Among these, DT2216, a candidate in phase I/II clinical trials, has demonstrated antitumoral activity in preclinical cancer models from different origins, not including melanoma.<h4>Methods</h4>By using several established and patient-derived BRAF wild type and mutated melanoma cells, we performed western blot analysis and MTT assay to study DT2216 effect on Bcl-xL protein levels and cell viability, respectively. This evidence concerns the gene BRAF and melanoma.
