MiR-146a expression levels and bisphenol A (BPA) value in placenta from pregnant women living in polluted area and pregnant women living in a non-polluted area. a The expression of mir-146a was studied in placenta from 40 pregnant women, undergoing therapeutic abortion occurring in the second trimester of pregnancy for fetal malformations and from 40 pregnant women living in a non-polluted area by microRNA assay-based quantitative RT-PCR following the Delta-Delta Ct method. RNU6B was utilized for an endogenous reference to standardize microRNA expression levels. The results were expressed as relative expression levels after calibration with the universal reference data. The asterisk indicates a significant difference between patients with control group. P < 0.05. b Placental bisphenol A (BPA) value between 40 pregnant women, undergoing therapeutic abortion occurring in the second trimester of pregnancy for fetal malformations and from 40 pregnant women living in a non-polluted area P < 0.05
