OBJECTIVE: To evaluate the expression of pentraxin 3 (PTX3) and tumor necrosis factor-alpha (TNF-α) in preeclampsia.
METHODS: Twenty-two preeclamptic patients, six preeclamptic patients with intrauterine growth restriction (IUGR) and 30 women with uncomplicated pregnancies were included in this study. The expression of PTX3 and TNF-α in placental tissue was analyzed by quantitative real-time polymerase chain reaction (qRT-PCR) and Western immunoblotting. Enzyme-linked immunosorbent assay (ELISA) was used to measure the concentration of PTX3 and TNF-α in maternal sera. The localization and immunoreaction of PTX3 and TNF-α in placenta were determined via immunohistochemistry (IHC).
RESULTS: Expression of PTX3 and TNF-α in placental tissues and maternal sera was significantly increased in preeclamptic patients, as well as in those with IUGR. PTX3 was mainly expressed in villous stroma, decidual cells and terminal villi, and TNF-α was mostly localized in trophoblast, vascular endothelial cells, decidual cells and in the stroma of the stem villi. Moreover, PTX3 expression was correlated with TNF-α expression in maternal sera of preeclamptic women.
CONCLUSIONS: PTX3 and TNF-α are increased in preeclampsia and are likely involved in the pathogenesis of preeclampsia.
