BAP1 and nonpapillary renal cell carcinoma: To ensure that this effect is not confined to one cell line, we knocked down the expression of BAP1 or SETD2 in RCC4 and BAP1 in A498 cells (A498 has an inactivating mutation in SETD2 so it is not suitable for SETD2 analysis), two additional VHL-deficient ccRCC cell lines.
