C57BL/6J mice have been widely used as a diet-induced obesity model because they trigger common feature of human metabolic syndrome. In the present study, C57BL/6J male mice were fed either high fat diet (HFD) or normal diet (ND) during 24-week period, and analyzed age-dependent liver proteome of mice in two groups using 2-DE combined with MALDI-TOF-MS. Among identified proteins, up-regulated proteins were subdivided to early (during the first 4 weeks) and late (20~24 weeks) markers that played a role in diet-induced obesity development. Important early markers included ketohexokinase, prohibitin, and late markers included 75 kDa glucose-regulated protein, citrate synthase, selenium-binding liver protein. Of these, 75 kDa glucose-regulated protein has already been linked to obesity; however, prohibitin protein involved in obesity were identified for the first time in this study. In order to validate the proteomic results and gain insight into metabolic changes between the two groups, we further confirmed the expression pattern of some proteins of interest by Western blot analysis. Combined results of proteomic analysis with Western blot analysis revealed that anti-oxidant enzymes were progressively decreased whereas cytoskeletal proteins were time-dependently increased with a higher magnitude in HFD mice.
