Effect of resistin on PGC-1α and mitochondrial metabolism in placental trophoblasts. BeWo cells were treated with indicated doses of human resistin for 24 h. a Protein lysates were subjected for Western blot analysis (N = 4 in each group); b total RNAs were reverse-transcribed and subjected for RT-PCR (N = 4 in each group); c BeWo cells were treated with indicated doses of human resistin in medium containing galactose for 24 h followed by assay for ATP levels (N = 8 in each group). Mean ± SD * P < 0.05; ** P < 0.01
