Abstract
Docetaxel is one of effective chemotherapeutics in the last few years, however, it is interfered by drug resistance in its further application. The aim of this study is to screen differentially expressed genes of docetaxel resistant cell line SPC-A1/Docetaxel and its parent cell line SPC-A1 with gene chip technique. The cDNA retro-transcribed from equal quantity mRNA derived from SPC-A1/Docetaxel and SPC-A1 cell lines. The mixed probes were hybridized with Affymetrix GeneChip HG-U133A2.0. The acquired image was analyzed by Affymetrix GeneChip Operating Software Version 1.0. Then, part of these results were verified by RT-PCR. A total of 934 differentially expressed genes were screened out, in which up-and down-regulated genes were 428 and 506 respectively. These genes involved in ABC transporter, apoptosis regulator, tubulin, signal transducer, enzyme and so on. These differentially expressed genes may be related to the mechanisms of docetaxel resistance in SPC-A1/Docetaxel cell line.
