Using SELDI-TOF-MS technology for screening serum markers of hepatic carcinoma in rats

摘要

Objective: To identify potential serum markers of hepatic carcinoma in rats through Surface-Enhanced Laser Desorption Ionization-Time of Flight-Mass Spectrometry(SELDI-TOF-MS) Technology. Methods: A rat model of hepatic carcinoma was established. The serum samples of hepatic carcinoma and normal rats were analyzed via SELDI-TOF-MS Technology. The changes of the serum protein fingerprint patterns were observed between the experimental group of hepatic carcinoma and the controls. The analysis was conducted by statistical software-Biomarker Wizard. Results: Fifty-six protein peaks in the serums were found. Within m/z 0-20 000, the protein peaks of m/z 1158, 8 835 and 15 302 of hepatic carcinoma serums were obviously higher in the rat models compared with those in the controls(P ＜ 0.01). Conclusion: Three peaks were considered as potential biomarkers according to the serum protein fingerprint patterns of the hepatic carcinoma group and the control group.
