Western blot analysis of the expression of VDR and StAR upon dexamethasone treatment.

<p>30 µg of mitochondrial proteins (A) or whole lysates (B) from untreated HaCaT cells (ctrl) and cells treated for 72 h with dexamethasone (Dex) were analysed by western blotting using an antibody anti-VDR, followed by immunostaining with anti-StAR and finally with anti-VDAC or anti-actin antibody for loading control. The blots are representative of a set of three independent experiments.
