The influences on the transfection efficiency when treated with specific endocytic inhibitors amiloride (a), chlorpromazine (b) and genistein (c) and cellular uptake of fluorescence labeled CaP (d, e, h) and CaP-MA-40 (f, g, i) nanoparticles after treated with specific endocytic inhibitors in HEK293T cells. Data were represented as the relative transfection efficiency to the untreated cells group. Data are displayed as mean ± SD (n = 3). *P < 0.05, compared with the untreated cells group, ^#P < 0.05, compared with the CaP group
