Popis: Many anticancer strategies rely on efficient induction of apoptosis. The need for development of drug combinations with a strong pro-apoptotic activity is of particular interest in melanoma resistant to currently available chemotherapeutic regimes. We studied the pro-apoptotic properties of combination of tanespimycin + tipifarnib in five melanoma cell lines representing various stages of tumor progression. Our results show that in cells derived from vertical- and metastatic-phase the combination of tested drugs is strongly cytotoxic and efficient in inducing apoptosis, as evidenced by activation of caspase-9 and caspase-3 and enhanced fragmentation of DNA.
