Fig. 5From: Melanoma cells replicate through chemotherapy by reducing levels of key homologous recombination protein RAD51 and increasing expression of translesion synthesis DNA polymerase ζCisplatin enhances the sensitivity of melanoma cells to PARP inhibitor olaparib. Five-day SRB growth assay on A375 melanoma cells in 96-well plates showing enhanced sensitivity to olaparib in the presence of 0.5 μM cisplatin. This cisplatin concentration is well below the IC50 value. In order to correct for the toxicity of cisplatin alone, for each curve growth is expressed as the percentage of the non-olaparib-treated control. Values plotted are mean % growth (±SEM) from three independent experimentsBack to article page
