WANG Bin, et al. Histone deacetylase inhibitors down-regulate hepatic expression of adhesion molecules in septic mice[J]. Journal of Chongqing Medical University, 2011,36(1):8-11. DOI: 10.13406/j.cnki.cyxb.2011.01.037.
Objective:To investigate the effects of histone deacetylase(HDAC) inhibitors on the expression of adhesion molecules in liver tissue and the infiltration of leukocytes in liver tissue during the progression of sepsis.Methods:C57BL/6 mice were pre-treated with two structure unrelated HDAC inhibitors
Trichostatin A or sodium butyrate
and then sepsis was induced by cecal ligation and puncture(CLP).At 18 h after CLP
hepatic expression of adhesion molecules
including intercellular adhesion molecule-1(ICAM-1) and E-selectin
were detected by immunohistochemical analysis.The formalin-fixed liver specimens were also stained with HE routinely for morphologic evaluation.In addition
myeloperoxidase(MPO) activity in liver tissue and serum aminotransferases levels were measured.Results:Treatment with HDC inhibitors down-regulated the expression of adhesion molecules.This was accompanied by reduced leukocyte infilatraion in the liver tissue
decreased MPO activity in hepatic homogenates as well as suppressed elevation of serum aminotransferases levels.Conclusion:HDAC inhibitors effectively suppressed the expression of adhesion molecules
thus significantly attenuated the recruitment of leukocytes and alleviated hepatic injury induced by sepsis.
