BAP1 and breast carcinoma: We confirmed these data by western blotting in a panel of BAP1-deficient cell lines from different entities reconstituted with an empty vector control or a vector encoding an HA-tagged wild-type BAP1 (or a catalytically inactive p.C91S mutant) [29], including the ccRCC cell line UMRC-6 (Figure 1C and S1B), the UM cell line UPMM2 (Figure 1D and S1C), the cholangiocarcinoma cell line TFK-1 (Figure S1D,E), and the breast cancer cell line HCC-1187 (Figure S1F,G).
