To explore the effects of Piper retrofractum (PR) on CCA cells death, apoptosis, and migration. Two CCA cells, KKU-100 and KKU-M452, were used in this study. Cells were observed the growth by sulforhodamine B (SRB), colony formation, cell cycle arrest, and reactive oxygen species (ROS) formation. Migratory capability was determined by Wound healing and matrigel migration method. From the results indicated that PR significantly suppressed the growth of both CCA cells through reducing cancer cells number, inhibiting colony formation, and arresting cell cycle distribution at G0/G1 phase in KKU-100 cells and S to G2/M phase in KKU-M452 cells. Furthermore, PR strongly increased late apoptosis and necrosis in both cancer cells via increasing ROS formation and decreasing mitochondrial function. In line with this finding, PR extracts suppressed migration in Wound healing and matrigel migration assay, especially in KKU-100 cells. Collectively, the present study suggested PR serve as an anticancer drug for the prevention and treatment of CCA.
