Exposure of the BRCA1-mut HCC-1937 cell line to olaparib and selinexor for 72 hours resulted in apoptosis of 49% of the cells as compared to apoptosis of 32% of the cells after exposure to olaparib and 28% after exposure to selinexor for 72 hours (Figure 2B). The gene discussed is BRCA1; the disease is hepatocellular carcinoma.
