| Outline of Final Research Achievements |
Biotin is a water-soluble B complex vitamin and functions as a co-factor of five indispensable carboxylases in cells. It was reported that serum biotin concentrations are significantly lower in atopic dermatitis patients. In this study, we investigated the effects of biotin intake on atopic dermatitis by using mouse model. However, no significant differences were detected in symptoms of atopic dermatitis between biotin-deficient and biotin-sufficient mice.
On the other hand, concentrations of several amino acids, such as methionine and cysteine were significantly lower in liver taken from biotin-deficient mice than biotin-sufficient mice. Moreover, anti-oxidant capacities were significantly lower in biotin-deficient cells than biotin-sufficient cells.
