Neuroblastoma (NB) expresses the tyrosine kinase receptors c-Kit, PDGFR-alpha and -beta-targets for STI-571. We investigated a possible combination therapy of STI-571 with retinoic acid (RA) and gamma-irradiation on NB cell viability in vitro. Expression of tyrosine kinase receptors and their ligands was examined in 6 NB cell lines by RT-PCR and FACS. The effect on cell viability was determined by MTT assay. Cell viability of all 6 NB cell lines was significantly inhibited after treatment with 20 microM STI-571 for 72h, two cell lines responding already to 10 microM. Cell lines responded irrespective of their mRNA status or cell surface expression of c-Kit, PDGFR-alpha and -beta. Co-incubation with 9-cis RA sensitized cells to the inhibitory effects of STI-571. However, pre-treatment with 9-cis RA resulted in resistance of NB cell lines to STI-571 and gamma-irradiation. Treatment of NB with STI-571 in combination with 9-cis RA might be a therapeutic strategy for patients in consolidation therapy who have completed gamma-irradiation therapy.
