Expression of Akt (A), Phospho-Akt (B) and XIAP (C) in cultured rat decidual cells in vitro in response to TGF-β3 (ng/mL) as demonstrated by Western blot analysis. β-actin blots shown were used as controls to correct for loading in each lane. Blots shown are from one representative experiment. Graphics represent Western blot densitometrical analysis. Data represent the mean ± SEM of four independent experiments. Columns with different letters are significantly different from each other (P < 0.05).
