Figure Lengend Snippet: Inhibitory effect of ORM1 on VIM/MAPK/MMP signaling pathway. A) Effect of ORM1 treatment on the phosphorylation of ERK, JNK, and p38 in C28/I2 and SW1353 cells was detected using western blot. Data is expressed as mean ± SD and analyzed using one‐way ANOVA followed by Tukey's post‐hoc test, n = 3, * p < 0.05, # p < 0.05 compared with the NC group. Expression of MMP13 and MMP3 (B), and the phosphorylation of extracellular signal‐regulated kinase (ERK), c‐Jun N‐terminal kinase (JNK), and p38 mitogen‐activated protein kinase (p38) (C) after overexpression of VIM with or without ORM1 treatment in C28/I2 and SW1353 cells. Data is expressed as mean ± SD and analyzed using one‐way ANOVA followed by Tukey's post‐hoc test, n = 3, * p < 0.05, # p < 0.05 compared with the Myc group. Expression of MMP13 and MMP3 (D), and the phosphorylation of ERK, JNK, and p38 (E) after knockdown of VIM in C28/I2 and SW1353 cells. Data is expressed as mean ± SD and analyzed using unpaired Student's t test (two‐tailed), n = 3, * p < 0.05, # p < 0.05 compared with the NC siRNA group. F) Expression of MMP13 and MMP3 after overexpression of VIM with or without inhibition of ERK, JNK, and p38 in C28/I2 and SW1353 cells. Data is expressed as mean ± SD and analyzed using one‐way ANOVA followed by Tukey's post‐hoc test, n = 3, * p < 0.05. G) The phosphorylation levels of ERK, JNK, and p38 in condylar cartilage of rats were detected by immunofluorescence, with the yellow lines showing the articular surface and the interface between bone and cartilage. H) Quantification of the phosphorylation levels of ERK, JNK, and p38 in condylar cartilage of rats based on the immunofluorescence. Data is expressed as mean ± SD and analyzed using one‐way ANOVA followed by Tukey's post‐hoc test, n = 5, * p < 0.05 compared with the UAC+NS group.
