Ghrelin Increases Beta-Catenin Level through Protein Kinase A Activation and Regulates OPG Expression in Rat Primary Osteoblasts
Figure 1
Representative Western blot (a) and quantification (b) of the effect of increasing concentrations of ghrelin (AG, 10−11–10−7 M, 1 h treatment) on β-catenin protein level in whole cell lysates of rat osteoblast-like cells. β-catenin levels are normalized on β-actin protein levels and results are expressed as the ratio of β-catenin amount measured in treated cells to the amount obtained in untreated cells. Data are the mean ± SEM of five experiments , versus untreated cells.
