Quantitation of TPH1/2 enzyme activity. As described in the methods section, the rate limiting enzyme, TPH (1 and 2) activity was measured in the placental tissues (Fig. 3A) and in the cultured trophoblasts (Fig. 3B) obtained from third trimester FGR pregnancies compared with gestation-matched control pregnancies. Fig. 3C depicts the total placental 5-HT content in FGR pregnancies compared with gestation-matched control. Concentrations of 5-HT are represented as nmol 5-HT/μg protein.
