3.4 The expression of BNDF was decreased in PE placentas
Finally, we compared the placental expression between PE and control group. The result of PT-PCR showed that BDNF mRNA in PE group was obviously decreased compared with control group (BDNF mRNA level: PE group vs. Control group, 0.6936±0.1472, n=21 vs. 1.350±0.2392, n=21, P=0.0245; Figure 1).
In accordance,the expression of BDNF protein in PE placentas was significantly lower than that in the control ones ( p = 0.0011), as shown in Figure 2,3 .
