Direct effects of melatonin on EtOH-induced osteoclastic differentiation in BMMs. BMMs were stimulated with RANKL in the presence of juglone (50 nM) or PIN1 siRNA (30 nM), EtOH (25 mM) and melatonin (100 μM) for 5 days. In vitro osteoclatogenesis was accessed by TRAP staining (A) and actin ring staining (B), counting of osteoclast (C), mRNA expression of osteoclast-specific marker genes (D). Similar data were obtained from three independent experiments. * statistically significant difference compared to the control groups (p < 0.05). # statistically significant difference in each group.
