Figure 4. Suppression of TRPV5 inhibits OC marker proteins expression. A, V-ATPase, TRAP, CTSK and Ca II expression after treatment by 1,25(OH)₂D₃ (VD), VD+RUR or VD + ECO were analyzed by western blotting. B, Quantitative analysis of V-ATPase, TRAP, CTSK and Ca II after treatment by 1,25(OH)₂D₃ (VD), VD+RUR or VD + ECO. Data means average ± SD (n = 9 each). Compared to the control group, ^* P < 0.05, ^** P < 0.01, compared to the VD group, ^# P < 0.05, ^## P < 0.01.
