RPS6 and hydrops fetalis: Immunofluorescent colocalization of p-rpS6 with POMC (using POMC-GFP mice), tyrosine hydroxylase (TH) or dopamine beta-hydroxylase (DBH) in cmNTS brain sections of fasted HF-fed mice indicated that some cmNTS cells expressing p-rpS6 also expressed POMC (Fig. 3d) or TH (Fig. 3e).
