<P>PROBLEM TO BE SOLVED: To provide an enhancer for expressing a biological defense factor, which can be performed in novel applications of a licorice extract. <P>SOLUTION: The enhancer for expressing the biological defense factor comprises, as an active ingredient, the licorice extract soluble in water and ethanol and containing no glycyrrhizin nor glabridin, having an activity of enhancing the expression of BCL-XL, survivin, P53, SOD and HO-1 that are biological defense function factors, and also having an activity of inhibiting the expression of iNOS. The enhancer can be used as a BCL-XL expression enhancer, a survivin expression enhancer, a P53 expression enhancer, an SOD expression enhancer, an HO-1 expression enhancer or an inhibitor of the expression of iNOS that has an oxidative stress promoting activity. <P>COPYRIGHT: (C)2013,JPO&INPIT |
