Abstract
Background : This study was designed to examine how glutathione, one of the nucleophilic sulfur compounds, effects the cisplatin cellular toxicity in the non-small cell lung cancer cell lines and normal lung epithelial cell line. Materials and Methods : Three cultured cell lines, the lung adenocarcinoma cell(NCL-H23), the lung squamous carcinoma cell(SK-MES-1) and the normal lung epithelial cell(L-132) line were exposed to various concentrations of cisplatin with or without glutathione. The relative viability was estimated as a means of measuring the cisplatin cellular toxicity using the MTT method. Results : In NCI-23, the response to cisplatin was sensitive but glutathione markedly increased the relative survival of the tumor cells by removing the antitumor effect of cisplatin. In both SK-MES-1 and L-132, the responses to cisplatin were less sensitive, and the chemoprotective effect of glutathione compared to and equal cisplatin dose was significantly higher in L-132 than in SK-MES-1(p<0.05). Conclusion : The protective effectes of of glutathione on cisplatin-induced cellular toxicity is more significant in normal lung epithelial cells than in squamous carcinoma cells.
