Glycyrrhiza ura lensis (Leguminosae) has long been known as an ant i-i nflammatory agent for gastric 띠cers ， arthri t is, and rheumaLism. 1'he f1avonoid glycyr ol isolated from Glycyrrhiza uralensis dramatically inhibits phorbol ester (PMA)-induced NF-kB-dependent transcriptional activity, as determined by luciferase activity in HEK293T cells To in vestigate the global gene expression profiling by glycyrol, we performed high-density oligonucleotide microarrays, Our microarray analysis showed that gl ycY I 이 inhi bited phorbol ester-induced NF-kB-dependent transcriptional activity in inflarnmatory-related gene expression, RT-PCR analysis based on microarry data showed that NF-kB-dependent genes such as CCL2‘ CCL7. CD44, and HSPB8 in addition to NF-kB itself were significantly down-regulated by glycyrol Treatment with glycyrol inhibited ]-kB degradation induced by PMA, suggesting that glycyrol has a potential anti-in flammatory activity by modulating NF-kB-dependent pathways. Also, the microarray data showed that glycyr이 appears to induce gene expression related to p53-dependent apoptosis t hrough ENDO G instead of CAD/DFF and AlF/PDCD8 as down stream apoptosis factor in HEK293T tumor cell s and to induce an added function as oncogenes in connection with apoptoslS
