Objective To explore the regulatory effects of thioredoxin on chemosensitivity of gastric cancer cells. Methods RT-PCR was employed to clone the full-length cDNA of thioredoxin (Trx) from human drug-resistant gastric cancer cell line SGC7901/VCR. The sense and antisense eukaryotic expression vectors corresponding Trx were constructed and transduced into gastric cancer cells SGC7901 and SGC7901/VCR by lipofectamine, respectively. MTT assay was used to evaluate the sensitivity of gene-transfected gastric cancer cells and control cells to anti-cancer drugs in vitro. Results The results indicated that SGC7901 cells transfected with Trx sense vector showed significantly decreased sensitivity to vincristine, cisplatin and adriamycin, while SGC7901/VCR transfected with Trx antisense vector showed significantly increased sensitivity to these drugs. Conclusion All these data suggested that Trx might participate in the formation of multidrug resistance of gastric cancer cells and alteration of Trx could regulate chemosensitivity of gastric cancer cells.
