Abstract Background: Cisplatin (DDP)-based chemotherapy is the mainstay of first-line therapeutic strategy for the treatment of advanced non-small cell carcinoma (NSCLC). However, the anticancer efficacy of DDP is often limited by the existence or development of chemoresistance. Thus, we investigated the effect of interferon-γ on DDPresistant A549 cell. Methods: Semi-quantitative RT–PCR was used to compare the differences of SOCS3 mRNA expression in both cisplatin-resistant A549 (A549/DDP) cell and the parental A549 cell. The cellular sensitivity to cisplatin, cell viability and apoptosis were detected by MTT, flow cytometry and Western blotting. Results: Semi-quantitative RT–PCR and western blotting showed that SOCS 3 expression was significantly down-regulated in A549/DDP cell compared to the parental A549 and normal human bronchial epithelial cells BEAS-2B.
