1.The change of high mobility group box-1 protein expression in the moose model with acute hepatic failure
Chinese Journal of Infectious Diseases 2010;28(4):209-213
Objective To study the expression-mode and dynamic transmutation of high mobility group box-1 (HMGB1) in hepatocytes of the mouse model with acute hepatic failure and to study the interaction beween HMGB1 and tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β). Methods The mouse model of acute hepatic failure was established by injecting D-galactosamine (D-GalN) and lipopolysaccharide(LPS). Immunohistochemistry SABC method was used to detect the HMGB1 expression at 6 time points. The enzyme linked immunosorbent assay (ELISA) was used to determine serum TNF-α. IL-1β levels. Paired t test was used for statistical analysis. Results The HMGB1 expression was detectable at 2 hours after injection, which dramatically increased over time and peaked at 24 hours after injection. The serum TNF-a level and IL-1β level increased right after injection. The TNF-a level peaked at 8 hours after injection with a maximum value of (473.42±22. 99) pg/mL. The IL-1β level peaked at 2 hours after injection with a maximum value of (724. 49±34. 24) pg/mL. Both cytokine levels slowly decreased after peaking. IL-1β level returned normal with (51. 49±36. 87) pg/mL. Conclusions HMGB1 is one of the most important factors during the development of acute hepatic failure, which can promote the secretion of TNF-α and IL-1β at early stage and be abundantly expressed under the effect of these cytokines at middle and late stages with the result of liver damage. This process is directly correlated with the development and severity of hepatic failure.
