Proteomics studies will be done in both tumor tissue and the circulating exosome from blood specimens. Then, the potential prognostic and predictive biomarkers will be searched by bioinformatics to find the correlations between exosome biomarkers and gallbladder carcinoma.', 'detailedDescription': 'Background:\n\nExosomes are formed by inward budding of late endosomes, producing multivesicular bodies (MVBs), and are released into the environment by fusion of the MVBs with the plasma membrane. It has been demonstrated that the content and function of exosomes depends on the originating cell and the conditions under which they are produced. Tumor exosome production, transfer and education of bone marrow cells supports tumor growth and metastasis.\n\nAims of the study:\n\nProteomics studies will be done in both tumor tissue and the circulating exosome from the gallbladder carcinoma patients. Then, the potential prognostic and predictive biomarkers will be searched by bioinformatics to find the correlations between exosome biomarkers and gallbladder carcinoma.\n\nMaterials and Methods:\n\nThe investigators will conduct a case-control study in 11 hospitals from China. Cases will be the patients with newly-diagnosed gallbladder carcinoma. The controls will be matched (1:1)by sex,race and age which will be selected from the patients receiving cholecystectomy due to gallstones from the same hospital with the cases. A total of 50 patients with gallbladder carcinoma will be recruited. The investigators will obtain the blood and tumor tissue samples for further analysis of proteomics studies. Exosome from blood specimens will be isolated and purified by sucrose gradient ultracentrifugation. The potential prognostic and predictive biomarkers will be searched by bioinformatics to find the correlations between exosome biomarkers and gallbladder carcinoma.
