Effect of ABCG2 on the uptake of photosensitizer in SW480 and SW480/ABCG2 cells. a, Overexpression of ABCG2 in SW480 was confirmed by immunoblotting and immunocytochemical assay using ABCG2 antibody. b, MTT assay was performed in SW480 and SW480/ABCG2 cells. c, SW480 and SW480/ABCG2 cells were incubated with 200 nM PPa for 16 h and then immunocytochemical assay for anti-abcg2 (Green), PPa (Red), and DAPI (blue) was applied. Data are means ± SEM from three independent experiments (*P < 0.05, **P < 0.01, #P < 0.0001)
