Research Abstract |
TRAIL is cytokine which can induce apoptosis against cancer cells, and has contributed to cancer prevention. We found that matrix metalloproteinase 8 (MMP-8) is one of the key factors responsible for the release of TRAIL, and we have shown that butyric acid bacterium promotes the release of MMP-8 and induces the release of endogenous TRAIL from neutrophils (Int J Oncol, 2013, 42:903). We therefore hypothesized that we could find the cancer preventive food factors by detecting factors to release MMP-8 with up-regulation of TRAIL. We then performed a screening for a variety of candidates such as the ingredients with immunostimulatory action. However, the candidate with sufficient effect was not found as compared with the butyric acid bacterium.
