Figure 9. IL-10 prevents high glucose-mediated suppression of osterix expression via the ERK pathway.
(A) MC3T3-E1 cells were treated with high glucose (72 hours) +/− IL-10 for 24 hours. RNA extracted and mRNA analysis of osterix (OSX) gene assessed by Q-RT-PCR and normalized to HPRT. (B) MC3T3-E1 cells were treated with high glucose (72 hours) +/− IL-10 for 15 minutes. Representative blots show protein levels analyzed by Western Blot as well as loading controls (ERK and Tubulin). Quantification of western blots for p-ERK/ERK, p-p38, and p-JNK. Values are averages ± standard error; n= 4–5 per group, *p<0.05, **p<0.01. Statistical analysis performed by One-way ANOVA followed by Fisher’s LSD post-test.
