The effect of ALA on osteogenic-related gene expression. RT-qPCR of β-catenin (a, d), Runx2 (b, e) and osterix (c, f) expression in primary OBs subjected to different treatments. Data are expressed as the mean ± SD from three independent experiments. ** p < 0.01, * p < 0.05 versus the vehicle treatment (con) in Fig. 6a-c. ## p < 0.01, # p < 0.05 versus the vehicle treatment (con) in Fig. 6d-f, && p < 0.01 & p < 0.05 versus PA 0.2 mM treatment in Fig. 6d-f by one-way ANOVA
