Fig. 3From: Propionibacterium acnes induces cartilaginous endplate degeneration by promoting MIF expression via the NF-κB pathwayP. acnes-induced MIF Production in CEP cells. a–d Western blot analysis of MIF, MMP-13, and Col II expression in CEP cells infected with P. acnes supernatant for 48 h in a concentration-dependent manner. e–f RT-qPCR analysis of MIF, MMP-13, and Col II mRNA expression infected with P. acnes supernatant for 24 h. *p < 0.05, **p < 0.01, ***p < 0.001. p values were analyzed by two-sided Student’s t test.
