Abstract
Phlogacanthus pulcherrimus T. Anderson (PPT) is an edible plant found in the northern and northeastern regions of Thailand. There is limited information about the anti-breast cancer activity of the ethanolic leaf extract of PPT. This study aimed to evaluate the effects of an ethanolic leaf extract of PPT on MCF-7 breast cancer cell lines. The biological effects, including cytotoxicity, cell apoptosis, colony formation, reactive oxygen species (ROS) formation and cell migration, were determined by a means of sulforhodamine B (SRB), acridine orange/ethidium bromide (AO/EB) staining, a clonogenic assay, flow cytometry and a scratch wound healing assay, respectively. The results demonstrated that the PPT extract showed cytotoxic on MCF-7 cells in a dose-dependent manner with 50% inhibitory concentration (IC50) values of 119.9 ± 12.1 and 51.3 ± 4.7 μg/mL at 24 h and 48 h incubation, respectively. In addition, the extract exhibited cell apoptosis in a dose-dependent manner when used at a concentration of 50–100 μg/mL and inhibited colony formation with an IC50 value of 26.0 ± 2.0 μg/mL when compared with the control group. The extract induced ROS formation in a dose-dependent manner when used at a concentration of 50–100 μg/mL. The extract suppressed MCF-7 cell migration, with significant effect at 25 μg/mL. These results indicate that PPT ethanolic leaf extract has an anticancer activity against MCF-7 breast cancer cells and may be useful for prevention and treatment of breast cancer.
