Furthermore, the A375, HT-144 and M74 human melanoma cell lines harbouring the mutation V600E of BRAF, also express the mutated form of several common and different proteins such as ATM in HT-144 cells, instead, in A375 and M74 cells the promoter of TERT is mutated [32,33,34], thus eliciting the reported different sensitivity to the treatment with (Bu2Sn)2TPPS and (Bu3Sn)4TPPS. Here, BRAF is linked to melanoma.
