BRCA1 and hepatocellular carcinoma: Our cell proliferation assay (Figure 2C) showed that both BRCA1/2 wild-type (MDA-MB-231) and BRCA1/2 mutant (HCC 1806) TNBC cell lines were sensitive to PARPi when Cdh1 was depleted, suggesting that Cdh1 depletion can cause PARPi sensitivity independent of its effect on BRCA1.
