Liraglutide Promotes Osteoblastic Differentiation in MC3T3-E1 Cells by ERK5 Pathway

Figure 7

XMD8-92 inhibited the protective effect of liraglutide in MC3T3-E1 cells. The protein expression of p-ERK was detected by western blot after the MC3T3-E1 cells were pretreated with 10 μM XMD8-92 for 1 h, followed by 100 nM liraglutide treatment for 48 h (a). Quantitative analysis of the protein level of p-ERK5 (b) in MC3T3-E1 cells after pretreated with 10 μM XMD8-92 for 1 h followed by 100 nM liraglutide treatment for 48 h.  < 0.05 compared with control,  < 0.05 compared with 100 nM liraglutide, and  < 0.05 compared with XMD8-92 group. C: control group; LIR: 100 nM liraglutide; X: XMD8-92; X + LIR: XMD8-92 with 100 nM liraglutide.
