BAP1 and breast cancer: Moreover, we found a uniform reduced BAP1 protein levels in renal carcinoma cell lines (Fig. S1A), lung cancer cell lines (Fig. S1B), and breast cancer cell lines (Fig. S1C) in comparison with the normal renal cells (HK‐2 cells), lung cells (WI38 and 16HBE cells), and breast cells (MCF10A cells), respectively.
