FOXP3 and renal cell carcinoma: Consistent with the results showed in Figure 1B, the FoxP3 expression level was much higher in the BAP1 mutation (769-P and UM-RC-6) and SETD2 mutation RCC cell lines (A704, Caki-1, and A498) than their specific wild-type cell lines (OS-RC-2, Caki-2, and 786-O) (Figure 1F).
