Objective:To oberserve the effect of small molecule anatagonists of XIAP(Embelin)on the multidrug resistance cells SGC7901 in vitro and in vivo.Methods:in vitro two groups of cultured SGC7901 cells were used:SG7901(group A)
the SGC7901 cells treated with Embelin(group B)
XIAP mRNA and protein levels of the cells of both groups were determined by TR-PCR
Western blot.MTr assay was performed to examine the IC

and CI.In vivo nude mice were divided into four groups:control group
VCR group
Embelin group
VCR assistance with Embelin group
the weight of tumor growth in the nude mice were measured.Results:Between group A and group B there was a significant difference in the expression of XIPA (P
