Figure 6. Overexpression of miR-361-5p inhibits the expression of MAP3K9, thus inhibiting the expression of MMPs in chondrocytes. (A) Protein band plots of MAP3K9, p-ERK1/2, p-NF-κB, MMP1 and MMP9. (B) Relative protein expression statistics of MAP3K9, p-ERK1/2, p-NF-κB, MMP1 and MMP9. N = 3; **P < 0.01, miR-NC vs. miR-mimic; nsP > 0.05, miR-NC+MAP3K9 OE vs. miR-mimic+MAP3K9 OE.
