Cinobufagin inhibits colony formation of human CCA. (A,B) Cell colony formation assay in human CCA cell line QBC939 treated with cinobufagin is shown; (C,D) cell colony formation assay in human CCA cell line RBE treated with cinobufagin is shown. Mean ± SD of triplicate experiments were plotted, ***P<0.001. CCA, cholangiocarcinoma.
