Analysis of gene expression profile of multidrug resistant MCF/DOX cell line after benflumetol derivative LY980503 treatment / 中国病理生理杂志

AIM: To investigate the effect of LY980503(a benflumetol derivative)on multidrug resistance of tumor cell line using DNA microarray. METHODS: Total RNA was extracted from multidrug resistant MCF/DOX cell line. cDNA microarray containing 320 cDNAs was used to detect the gene expression profile. RESULTS: 9 down-regulated genes and 1 up-regulated gene were identified after multidrug resistant MCF/DOX cells were treated with LY980503. CONCLUSION: LY980503 can effectively reverse the resistance of MCF/DOX to DOX in vitro by adjusting the expression of multi-genes.
