Abstract 4451: The effects of anthocyanins from the fruit of Vitis coignetiae Pulliat on NF-κB and NF-κB-regulated gene expressions in human lung cancer cells

Abstract

Abstract Vitis coignetiae Pulliat (Meoru in Korea) has been used as a remedy for inflammatory diseases and various cancers. We isolated anthocyanins from Meoru. We previously suggested that anthocyanins from fruits of Vitis coignetiae Pulliat (Meoru in Korea) should have anti-invasive effects through suppression of NF-κB activation. Here, we investigated their effects on NF-κB-regulated gene products and cellular responses in human lung cancer cells. The anthocyanins inhibited NF-κB activation in a dose-dependent manner. TNF-α augmented proliferation, migration and invasion of A549 cells. The anthocyanins inhibited the augmented proliferation, migration and invasion of the cancer cells by TNF-α. We also found that the anthocyanins suppressed NF-κB-regulated proteins involved in caner proliferation, metastasis and anti-apoptosis. The anthocyanins inhibit NF-κB activity by inhibiting IκBα phosphorylation. Taken together, this study suggested that the anthocyanins isolated from fruits of Vitis coignetiae Pulliat inhibit the NF-κB activation and downstream proteins, which may be a factor in their anticancer activities of fruit of Vitis coignetiae Pulliat.
