| Objective(s): Atherosclerosis is the main cause of cardiovascular disease (CVD) which has a key role in the development of coronary artery disease (CAD). Based on clinical studies, HSP60 is the only HSP that can cause atherosclerosis. In this paper, the expression level of HSP60 and the pathogenic degree of its cloned part was investigated in atherosclerosis condition. Materials and Methods: After the designation of the specific primers for HSP60, PCR was done by the Pfu enzyme. Subsequently, the PCR products were cloned into a prokaryotic expression vector pET-28a. The resultant recombinant vector was transferred in BL21 and purified. Purification of protein was done by the Nickel affinity column. After confirmation of Western blotting and HSP60 protein purification, purified protein concentration was measured by the Bradford method, and purity was analyzed by SDS PAGE 12%. New Zealand rabbits were tested as an animal model. At the next step, the recombinant protein was injected into the animal model that was on a fatty diet. Results: The prokaryotic expression plasmid pET28a-hps60 was successfully constructed, the HSP60 protein was expressed and purified in Escherichia coli BL21 (DE3). We found that the rabbit that was receiving the recombinant vaccine with the fatty diet showed a lower amount of fat deposition at the media endothelial level than the rabbit which received only the fatty diet. Conclusion: Taking recombinant protein concomitant with a fatty diet, causes betterment of atherosclerosis via decreasing aggregation of cholesterol and thickness of the endothelial media. | ||
