Oyaksungisan (OY) is a traditional herbal formula broadly used to treat beriberi, vomiting, diarrhea, and circulatory disturbance in Asian countries from ancient times. The effect of OY on cancer, however, was not reported until now. In this study, we have demonstrated that OY inhibits cell proliferation and induces cell deathviamodulating the autophagy on human colon cancer cells. In HCT116 cells, OY increased the ratio of LC3-II/LC3-I, a marker of autophagy, and treatment with 3-MA, an inhibitor of autophagy, and considerably reduced the formation of autophagosomes. In addition, OY regulated mitogen-activated protein kinase (MAPK) cascades; especially, JNK activation was closely related with autophagy effect by OY in HCT116 cells. Our results indicate that autophagy induction is responsible for the antiproliferative effect by OY, despite the weak apoptosis induction in HCT116 cells. In conclusion, OY might have a potential to be developed as an herbal anticancer remedy.

Zedoary turmeric oil (ZTO) is a volatile oil that is extracted from the dry rhizome of Curcuma zedoaria with a variety of biological activities, including anti-tumor activity. However, there is a lack of knowledge about the effect and mechanism of ZTO in human colon cancer cells. The aim of this study was to examine the potential efficacy of ZTO against human colon cancer cells (HCT116) and to uncover the molecular mechanisms of its anti-tumor effects. The anti-proliferative activity of ZTO was determined by the MTT assay, cell counts and colony formation assay. Senescent cells were detected using SA-β-Gal staining, while apoptosis and the CD44+ subpopulation were evaluated by flow cytometry. The expression levels of senescence- and apoptosis-related proteins were examined using western blotting. The results showed that treatment with ZTO significantly inhibited the growth of HCT116 cells and caused senescence and apoptosis in a dose- and time-dependent manner. Western blotting revealed that ZTO significantly increased the expression of senescence- and apoptosis-related proteins p16, p21, and p53 and the phosphorylation of ERK. Moreover, ZTO treatment reduced the cancer stem-like CD44 positive cell population. These findings suggest that ZTO inhibits human colon cancer cells by inducing senescence and apoptosis.
