Effects of 1,25(OH)2D3 on Aβ-induced changes in vitamin D receptor (VDR) (a) and glial cell line-derived neurotrophic factor (GDNF) (b) protein expressions. SH-SY5Y cells were incubated with 1 μM Aβ(25-35) prior to the addition of 0.1 and 10 nM 1,25(OH)2D3 for 24 h.* Significantly differs from the control group (statistical analysis was performed using Student’s t test). Bars of Aβ, Aβ + 0.1 nM 1,25(OH)2D3, and Aβ + 10 nM 1,25(OH)2D3 with different letters significantly differ from each other (p < 0.05) (statistical analysis was performed using one-way analysis of variance (ANOVA) with Duncan’s post-hoc analysis). All data are expressed as mean ± SD of three experiments, and each experiment included triplicate repeats.
