Western blot analysis of UPF protein expression in MM6 cells.

<p>Western blot analysis of UPF protein expression in MM6 cells incubated with and without TGFβ (1 ng/ml) and calcitriol (50 nM) for 24 h. Differentiation-dependent relative changes in UPF protein expression compared to undifferentiated samples (set to 1) are given as the mean+SE of three independent experiments.
