RUNX2 and nonpapillary renal cell carcinoma: In order to explore the role RUNX2 played in MAPK11/P‐MAPK11‐mediated cellular proliferating, migrating and invasive behaviour of ccRCC, the MAPK11 knockdown cells were transfected with virosome that contains RUNX2 in full length (shRNA‐MAPK11/LV‐RUNX2).
