To determine whether ARL4C knockdown affects the proliferative capacity of ccRCC cells, we first compared the cell proliferation of the si-NC group versus the si-ARL4C group using CCK-8 (Figures 6(a) and 6(b)) and colony formation assays (Figures 6(c) and 6(d)). Here, ARL4C is linked to nonpapillary renal cell carcinoma.
