Abstract:
Objective To evaluate the expression and discussion on high mobility group protein ( HMGB1 )/toll like receptor 4 ( TLR4 ) and NF-κB possible role in the signaling pathway in preeclampsia .Methods Ten patients with mild preeclampsia(MP), 20 patients with severe preeclampsia (SP) and 30 cases of normal pregnancy were recruited the same period.To check the expression of the HMGB1,TLR4,NF-κB P65 protein in placenta tissue using Immunohistochemical staining .Levels of HMGB1, TLR4, NF-κB P65 in blood serum were measured by ELISA.Results 1)ExpressionofHMGB1,TLR4,NF-κBP65wereincreasedascomparetocontrolgroup(P<0.05);HMGB1,TLR4,NF-κB P65 in placenta of patients with severe preeclampsia and mild preeclampsia failed to show significant difference .2) HMGB1,TLR4,NF-κB P65 in women with preeclampsia was significantly higher than control group ( P<0.05 ); HMGB1,TLR4,NF-κB P65 in women with severe preeclampsia showed a higher level as compared to mild preeclampsia (P<0.05).Conclusions HMGB1,TLR4 and NF-κB P65 were over-ex-pressed in the placenta tissue and serum in patients with preeclampsia , which indicated that HMGB1,TLR4 and NF-κB P65 may play an important role in the development of preeclampsia .
