Abstract

Objective: To investigate the differential expression of RPL6/Taxreb107 between drug-resistant gastric cancer cell line SGC7901/ADR and gastric cancer cell line SGC7901 as well as its correlation with multiple-drug resistance (MDR) in gastric cancer cells.<br />Methods: Total RNA was extracted from SGC7901 and SGC77901/ADR, with internal control RT-PCR, Northern blot, gene cloning and expression, construction of eukaryotic expression vector, gene transfection by electroporation. The accumulation and retention of ADR in transiently transfected cell was detected by flow cytometry.<br />Results: The internal control RT-PCR and Northern blot showed high RPL6/Taxreb107 expression in SGC7901/ADR cell line. Sense and antisense eukaryonic expression vectors demonstrated by double enzyme digestion were successfully transfected into gastric cancer cell line SGC7901 and SGC7901/ADR respectively by electroporation. The accumulation and retention of ADR detected 48 hours after transfection showed that RPL6 gene had shown effect on drug resistance in gastric cancer cell.<br />Conclusion: The high expression of RPL6/Taxreb107 in drug resistant gastric cancer cell shows its correlation with multiple-drug resistance in gastric cancer.
