摘要：

In this report, we investigated the role of oxidative stress in Physalis angulata-induced apoptosis of human oral cancer cells. P. angulata-induced apoptosis was characterized by nuclear morphological changes, membrane blebbing and activation of caspase-9. Exposure of HSC-3 cells to P. angulata caused production of reactive oxygen species and up-regulation of oxidative stress markers heme oxygenase-1 (HO-1), Superoxide dismutase (SOD), heat shock protein 70 (HSP70) and caspase-4. Down-regulation of HO-1, SOD and HSP70 proteins expression by attenuation of oxidative stress, pretreatment with glutathione or N-acetylcysteine, significantly decreased P. angulata-triggered cell death. The present study also demonstrated that the mitochondria and the endoplasmic reticulum are the targets of P. angulata in HSC-3 cells. Our results revealed that: (1) reactive oxygen species may play a dominant role in this process, (2) A angulata induces oxidative stress in HSC-3 cells, (3) P. angulata-initiated apoptosis is caused through oxidative stress-dependent induction of heme oxygenase-1, Cu/Zn SOD and HSP70 proteins expression and (4) antioxidants inhibited P. angulata-induced cell death through inhibition of the proteins expression of HO-1, Cu/Zn SOD and HSP70.
