BACKGROUND/OBJECTIVES: The study was conducted to investigate the efficacy of the combination treatment of phytochemical resveratrol and the anticancer drug docetaxel (DTX) on prostate carcinoma LNCaP cells, including factors related to detailed cell death mechanisms.
MATERIALS/METHODS: Using 2-dimensional monolayer and 3-dimensional spheroid culture systems, we examined the effects of resveratrol and DTX on cell viability, reactive oxygen species (ROS) levels, mitochondrial membrane potential, apoptosis, and necroptosis by MTT, flow cytometry, and Western blotting.
RESULTS: At concentrations not toxic to normal human prostate epithelial cells, resveratrol effectively decreased the viability of LNCaP cells depending on concentration and time. The combination treatment of resveratrol and DTX exhibited synergistic inhibitory effects on cell growth, demonstrated by an increase in the sub-G0/G1 peak, Annexin V-phycoerythrin positive cell fraction, ROS, mitochondrial dysfunction, and DNA damage response as well as concurrent activation of apoptosis and necroptosis. Apoptosis and necroptosis were rescued by pretreatment with ROS scavenger N-acetylcysteine.
CONCLUSIONS: We report resveratrol as an adjuvant drug candidate for improving the outcome of treatment in DTX therapy. Although the underlying mechanisms of necroptosis should be investigated comprehensively, targeting apoptosis and necroptosis simultaneously in the treatment of cancer can be a useful strategy for the development of promising drug candidates.
