Abstract:
Objective To study the effects of nuclear factor-?B(NF-?B)decoy oligodeoxynucleotide(ODN)on the preeclamptic umbilical serum induced expression of precollagen Ⅰ,Ⅲ mRNA and tumor necrosis factor-?(TNF-?)in cultured human umbilical artery smooth muscle cells (HUASMC).Methods Primary cultured HUASMC of normal pregnancy were divided into four groups: group A(HUASMC were incubated with umbilical serum of normal pregnancy);group B(HUASMC were incubated with umbilical serum of preeclampsia);group C(HUASMC were transfected with NF-?B cis decoy ODN 48 h before incubation with umbilical serum of preeclampsia);group D(HUASMC were transfected with NF-?B scramble ODN 24 h before incubation with umbilical serum of preeclampsia).NF-?B cis decoy ODN and NF-?B scramble ODN were transfected with cationic lipofectamine to the latter two groups,respectively.The proliferation of human umbilical artery smooth muscle cells was evaluated by methyl thiazolyl tetrazolium and the apoptosis was analyzed by flow cytometry.The expression levels of precollagen Ⅰ,Ⅲ mRNA were detected by RT-PCR,the expression levels of TNF-? were detected by western blot.Results(1)The proliferation of group B(0.19?0.02)and group D(0.18?0.03)was significantly increased as compared with those of group A(0.11?0.02)and group C(0.14?20.02)(P0.05).(5)The expression of TNF-? of group B(0.74?0.11),group C(0.36?0.09)and group D(0.79?0.12)were significantly higher than that of group A(0.15?0.03)(P0.05).Conclusions NF-?B cis decoy ODN could down-regulate the proliferation,as well as the expression levels of precollagen and TNF-? of HUASMC induced by umbilical serum of preeclampsia.NF-?B may play an important role in the pathogenesis of placental artery abnormalities in preeclampsia.
