The cytotoxic effect of varlitinib on CCA cells and cholangiocyte.
Notes: Four CCA cell lines and nonmalignant cholangiocyte were treated with varlitinib at concentrations ranging from 0.1 to 10 µM in 0.5% DMSO for 72 hrs. After incubation, cellular proteins of the viable cells were measured using the sulforhodamine B assay.
