Abstract
Monoclonal antibody (McAb) is the key tool for cancer immunodiagnosis and immunotherapy. In this study, a cell clone which kept secreting high-titer IgG1-type McAb named NJ001 against human non-small cell lung cancer (NSCLC) cells was obtained. The antigen named SP70 of NSCLC specifically identified by NJ001 was proved to be a protein with the relative molecular mass (Mr) of 70kDa. The results of immuno histochemical staining indicated that NJ001 could positively react to NSCLC, but negatively or weak positively react to human small-cell lung cancer (SCLC), pulmonary pseudo tumor and other epithelial tumors. In soft agar assay, the colony formation efficiency in NJ001 groups decreased in a dose-dependent manner. For the concentration of 100 μg/ml, 200 μg/ml and 400 μg/ml, the inhibition ratio of colony formation was 23.4%, 62.5% and 100% respectively. Meanwhile, NJ001 caused significant reduction in tumor volume and tumor weight compared to control mice in lung cancer xenograft model. The tumor growth inhibition ratio in 200 μg, 400 μg and 800 μg NJ001 groups was 10.44%, 37.29% and 44.04%, respectively. NJ001 also led to obvious cytomorphological changes and induced the apoptosis of human lung adenocarcinoma cell line SPCA1 significantly. The newly developed NJ001 selectively reacted to NSCLC and exhibited anti- tumor activity both in vitro and in vivo . NJ001 is of great value concerning immunodiagnostics and immunotherapy for NSCLC and holds promise for further research regarding the mechanism underlying tumor progression of NSCLC.
