Objective To screen the tumor specific antigens, and explore new methods for diagnosis and therapy of tumor. Methods Hela cells, the human cervical carcinoma cell line, were used to immunize the BALB/C mice, and the positive hybridomas were screened by rosette formation screening system in human carcinoma cell line Colo205, Burkitt lymphoma cell line, Raji, etc. The immunofluorescence staining and flow cytometry analysis were performed to characterize if the prepared monoclonal antibodies (mAb) could reorganize the natural membrane antigen expressed on Hela, Colo205, Raji, PLA801, 7901, Jurkat, 293T, ECV304 and resting or activated human peripheral blood mononuclear cells (PBMC). Furthermore, the membrane protein of Hela, Raji and Sp2/0 cells was segregated by ultracentrifugation and the mAbs were cross-linked with the Sepharose CL-4B. In order to identify the molecules which could be recognized by the prepared mAbs, immunoprecipitation was performed to purify the tumor antigen candidates with the cell membrane protein from Hela, Raji and SP2/0 (as negative control) through Sepharose CL-4B cross-linked with the prepared mAbs. Finally, western blotting was performed to detect the molecular weight of the products from the immunoprecipitation. Results Three mAbs were obtained which could recognize the tumor antigen candidates expressed in several human carcinoma cell lines, such as Hela, Raji and Colo205, and some embryonic cell lines, such as 293T and ECV304, but they could not bind to Jurkat, PLA801, 7901, SP2/0, resting or activated human PBMC. Western blotting results indicated that the three mAbs could recognize a 47kD molecule which expressed in Hela and Raji but not on SP2/0 cell membrane. Conclusion Three mAbs, which can recognize tumor membrane antigen candidates, are obtained, providing useful tools for screening and identify the tumor specific antigens.

Purpose To investigate the imaging characteristics and accuracy of diagnosing pilocytic astrocytoma (PA) with perfusion weighted imaging (PWI), diffusion weighted imaging (DWI), magnetic resonance sprectroscopy, susceptibility weighted imaging (SWI) and diffusion tensor imaging. Material and Methods MRI imaging of 11 patients with PA was retrospectively analyzed for functional imaging features. Results In 11 patients with PA, there were 9 mixed cystic and solid lesions, 1 case of cystic lesion and 1 case with solid lesion. Ten lesions showed mixed hypointensity on T1WI, and mixed hyperintensity on T2WI and FLAIR. One case was hypointense on T1WI, and hyperintense on T2WI and FLAIR. Prominent contrast enhancement was seen in the solid portion, capsular wall and mural nodules. On SWI 3 cases showed patchy low signal, 2 cases of dot-like low signal and 2 cases without low signal, with average intratumoral susceptibility signal intensity classification of 1.57. PWI findings were characterized by high perfusion with relative cerebral blood volume averaging 2.64±1.22. There was elevated choline component in the solid portion with significantly decreased NAA with average Cho/NAA ratio of 5.13±4.72 (1.46-15.26). Lactate peak was increased in 5 cases. On DWI there was limited diffusion in 1 case. 7 cases did not demonstrate limited diffusion with average relative apparent diffusion coefficient of 1.60±0.58. Conclusion Most MRI features of pilocystic astrocytoma are consistent with low grade glioma. There are characteristic functional imaging findings with higher perfusion than other gliomas. Functional MRI can evaluate tumor metabolism and prognosis.
