Abstract:
OBJECTIVETo investigate the feasibility of using cartilage link protein of hyaluronic acid (HA-CLP) for defining the tumor boundary in a mouse model of lung carcinoma.
METHODSLung carcinoma was induced in KM mice by chemical carcinogenesis. HA-CLP separated from bovine cartilage and purified by affinity chromatography was labeled with (125)I for autoradiography. Immunohistochemical analysis and Western blotting were used to examine the efficiency of HA-CLP in defining the boundaries of the lung tumors.
RESULTSWith autoradiography, the clearest image of lung cancer was obtained at 2 h. With immunohistochemical method, the tumor boundary was the most clearly displayed at 2 h when the strongest signals of HA-CLP was detected; Western blotting also showed the clearest bands of HA-CLP at 2 h.
CONCLUSIONHA-CLP has the immunogenicity of HABP, and can efficiently indicate lung tumor boundary in autoradiography and immunohistochemistry.
