The level of pERK1/2 was affected by LCN2. HK-2 (A) and HEK-293 (B) were transfected with negative control (NC) siRNA or LCN2 siRNA 1/2/3, and the expressions of LCN2 and GAPDH were analyzed by western blot. (C) HK-2 and HEK-293 were transfected with NC siRNA or LCN2 siRNA1/2/3 pools, and the expressions of p-ERK1/2, ERK1/2, LCN2 and GAPDH were analyzed by western blot. (D) HK-2 and HEK-293 were transfected with vector or LCN2, and the expressions of p-ERK1/2, ERK1/2, LCN2 and GAPDH were analyzed by western blot. HK-2 (E) and HEK-293 (F) were treated with rhLCN2, and the expressions of p-ERK1/2 and ERK1/2 were analyzed by western blot. All experiments were repeated at least three times.
