Abstract
Context
Hyperoside was used to treat cardiovascular disease for many years in China. It was shown great effect on regulation of lipid metabolism. But there is lack of reports about the effects of hyperoside on liver diseases.
Objective
This study was designed to investigate the potentially protective effects of hyperoside and the role of transcription factor nuclear factor-erythroid 2(NF-E2)-related factor 2 (Nrf2) signaling in the regulation on Carbon Tetrachloride (CCl4)-induced chronic liver fibrosis in mice.
Materials and methods
All mice were divided into six groups containing 6 animals per group. Mice in different group were given relative processing for 4 weeks. The potentially protective effects of hyperoside on CCl4-induced chronic liver fibrosis in mice were depicted histologically and biochemically.
Results
CCl4 administration caused a marked increase in the levels of serum aminotransferases, serum monoamine oxidase (MAO) and lipid peroxidation, MAO in mouse liver homogenates. Also decreased activities of cellular antioxidant defense enzymes were found after CCl4 exposure. Histopathological changes induced by CCl4 including regenerative nodules, deteriorated parenchyma. Hyperoside and silymarin reduced these changes and attenuated the pathological effects of CCl4 induced liver injury. In addition, hyperoside exhibited antioxidant effects in vitro. In Western blot analysis, the protein level of Nrf2 was downregulated after CCl4 administration and reversed by hyperoside.
Conclusion
Hyperoside increased the activity of the antioxidant and phase II detoxifying enzymes through the activation of Nrf2 nuclear translocated in the CCl4-induced liver fibrosis mice.
期刊介绍：
Cessation. The international multidisciplinary journal is devoted to the publication of studies covering the whole range of experimental research on disease processes and toxicology including cell biological investigations. Its aim is to support progress in the interdisciplinary cooperation of researchers working in pathobiology, toxicology, and cell biology independent of the methods applied. During the past decades increasing attention has been paid to the importance of toxic influence in the pathogenesis of human and animal diseases. This is why Experimental and Toxicologic Pathology meets the urgent need for an interdisciplinary journal felt by a wide variety of experts in medicine and biology, including pathologists, toxicologists, biologists, physicians, veterinary surgeons, pharmacists, and pharmacologists working in academic, industrial or clinical institutions.
