To analyze the effect of L-NG-nitroarginine methyl ester (L-NAME)-induced FGR and associated preeclampsia (PE) on p-mTOR signaling in the placenta, we performed fluorescent immunohistochemical staining using anti-phospho-mTOR (Ser2448) antibody on 13 d.p.c. (Figure 1). Here, MTOR is linked to preeclampsia.
