ABSTRACT
Objective To isolate and identify differential expression genes associated with multidrug resistance of leukemia . Methods Differential expression genes between leukemia cell line K 562 and resistant cell lines K562/DOX were isolated by using suppression subtractive hybridization (SSH) technique .Total RNA were extracted .cDNA were synthesized and digested by restric-tion enzyme Rsa Ⅰ ,then connected with adopter1 and adopter2R ,and linked with pMD19-T vector .Constructed vectors were trans-ferred into E .coli .Subtracted cDNA library was constructed ,and the positive clones were screened according to base sequences and homologous sequences .The differential expression genes were indentified by comparison analysis of Gene Bank database .Results A total of 220 differential expression genes were sequenced ,including hemoglobin ,ribosomes and mitochondria related genes ,and heat shock factor binding protein 1 (HSPB1) gene and other genes .Conclusion SSH method and molecular cloning technique could be used to construct subtracted cDNA library of differential expression genes between drug resistant and not -resistant leukemia cells , which might be useful for further screening and cloning of differential expression genes of multidrug resistant tumor cells .
