| Research Abstract |
Biotin is a water-soluble B complex vitamin found in all organisms. To elucidate the mechanisms of inflammatory regulation by biotin, a holocarboxylase synthetase knock-down macrophage (HCS-KD cells) was constructed. The holocarboxylase synthetase (HCS) is a key-enzyme in cellular biotin metabolisms. The production of tumor necrosis factor-α, an important bioactive protein that involved with inflammation, was decreased in the HCS-KD cells. On the other hand, CD11b, an adhesive protein that involved with inflammation, was up-regulated in the HCS-KD cells.
