Abstract:
30% was considered sensitive and the rate ≤30% was considered resistant;and the 6 specimens were divided into 2 group according to the above standard.cDNA microassay combined with clustering analysis was used to screen for resistance-related genes.Semi-quantitative RT-PCR was used for verification of HDAC1 gene expression.Results:Three of the 6 glioma specimens belonged to the drug resistance group and the other 3 to the drug sensitive group.cDNA microarray analysis combined with cluster analysis screened out 21 genes,with 6 up-regulated and 15 down-regulated.High expression of gene HDAC1 was noticed in all the 6 specimens by semi-quantitative RT-PCR,and the trend was similar to that by microassay.Conclusion:The primary drug resistance of glioma may be associated with the 21 genes screened by cDNA microarray;the detailed mechanisms for drug controlling still need to discussed in the future.
