Figure 3.

Protein expression levels of retinoic acid receptors (RARs) in normal (Ctr) and hypoplastic (N) lung explants treated with bombesin (Bomb), ghrelin (Grl) as well as bombesin plus RA (Bomb + RA) or ghrelin plus RA (Grl + RA) in normal lung explants

A, RARα expression. B, RARβ expression. C, RARγ expression. Examples of representative blots are shown. Protein levels were normalised to β-tubulin, which was used as a loading control. The data are presented as means ± SEM. *P < 0.05; **P < 0.01; ***P < 0.001.
