Apoptotic activity of demethoxycurcumin in MG-63 human osteosarcoma cells

open access: yesInternational Journal of Oral Biology, 2021
Demethoxycurcumin (DMC), which is a curcuminoid found in turmeric, has anti-proliferative effects on cancer cells. However, the effect of DMC on osteosarcoma has not been established. The aim of this study was to examine the effects of DMC on cell growth and apoptosis induction in MG-63 human osteosarcoma cells.
