Abstract: In other to investigate the relationship between DNA2protein crosslinks (DPC) and human lung cancer , we have used a sensitive 125Ⅰ2postlabelling assay to detect the formation of DPC in tissues to various cell type of human lung cancer. The results were showed that DPC was increased in lung cancer tissues comparing with its neighbored normal tissues , suggesting that DPC may play a part in the development of lung cancer. No significance differences were observed in DPC of tissues between adenocarcinoma and epidermoid carcinoma , and in DPC of lung cancer tissus between smoker and non2smoker.

Key words: DNA-protein crosslinks, lung cancer, smoking
