NQO1 siRNA reduced KKU-100 cell proliferation. NQO1-knockdown cells using siRNA were subjected to clonogenic survival assay. NQO1-knockdown CCA cells were plated at cell densities of (A) 300 and (B) 600 cells/well and cultured for another 10 days. The cell colonies were counted at 6, 8 and 10 days. (C) Representative images of the clonogenic survival assay of the cell density at 600 cells/well cultured for 8 days. Data are presented as the mean ± standard error of the mean from three independent experiments. *P<0.05 vs. control. NQO1, NAD(P)H:quinone oxidoreductase 1; siRNA, small interfering RNA; NT, non-targeting siRNA.
