Abstract

Korean mugwort herb is a preparation of dried leaves from Artemisia species and has been used as a traditional medicine in Asia. An oligosaccharide fraction, AVF3, purified from the preparation promoted survival of the mouse thymocytes in culture. A mouse gene array study suggests that the AVF3 may modulate Fas/FasL dependent apoptotic cell death and thus has influence on the survival of the thymocytes in culture. RT-PCR analysis confirmed the down-regulation of the Fas gene by the AVF3 treatment, supporting that the AVF3 modulated thymocyte death by suppressing the Fas gene expression.
