IL-32 levels are upregulated in the placenta and serum of patients with sPE. a Immunoblotting for IL-32 in placental lysates from patients with sPE (n = 6) or nPTB (n = 6). b q-PCR analysis of IL-32 in placental tissues from patients with sPE (n = 22) or nPTB (n = 12). c Immunostaining for IL-32 on the free villous (FV) and BP of placental sections from patients with sPE (n = 8) or nPTB (n = 8). Scale bar = 100 μm. d ELISA analysis of the IL-32 concentration in the serum of sPE patients (n = 36) and gestational age-matched NP (n = 27) women. e The correlation of the IL-32 concentration in serum samples and IL-32 expression level in placentas (n = 22) from sPE patients. f q-PCR analysis of IL-32 isoforms such as IL-32α, IL-32β, and IL-32γ in placental tissues from patients with sPE (n = 22) or nPTB (n = 12). Error bars, mean ± SD. The data were analyzed by an unpaired t test. *P < 0.05; **P < 0.01; ***P < 0.001
