Western blot results showed that placenta express ENaCβ protein with a molecular mass of 95 kDa protein; expression of ENaCβ protein was significantly lower in placenta from preeclampsia patients (ROD value 0.4848±0.01812, n = 48) than that from normal pregnancy (ROD value 0.9056±0.03886, n = 44; P<0.05; Figure 5B). Here, SCNN1B is linked to preeclampsia.
