Pharmacological activation of Hh signaling by PM restrained osteoclast-specific genes expressions under RANKL stimulation in vitro. qPCR analysis of relative mRNA levels of osteoclast-specific genes, including Nfatc1
(A), c-Fos
(B), Ctsk
(C), Dcstamp
(D), Acp5
(E), Oscar
(F), Atp6v0a3
(G), and Atp6v0d2
(H), in BMMs stimulated with RANKL for 6 days in the presence of 0, 0.5, 1, or 2 μM PM. Expression of each target gene was normalized by 18S ribosomal RNA. The relative changes in mRNA level were analyzed by 2-ΔΔCT method. All values were calculated from three independent biological replicates and presented as mean ± SD. **P<0.01, compared with vehicle-treated group.
