Abstract
The sphingolipid composition and multidrug resistance status of three human neuroblastoma cell lines were established. SK-N-FI cells displayed high expression and functional (efflux) activity of P-glycoprotein, while multidrug resistance-related protein 1 was relatively abundant and most active in SK-N-AS cells. These two cell lines exhibited higher sphingolipid levels, compared to SK-N-DZ, which had the lowest activity of either ATP-binding cassette transporter protein. SK-N-DZ cells also differed in ganglioside composition with predominant expression of b-series gangliosides. In conclusion, these three neuroblastoma cell lines offer a good model system to study sphingolipid metabolism in relation to ATP-binding cassette transporter protein function.
