Article Title: MEK1/2 Inhibitor (GDC0623) Promotes Osteogenic Differentiation of Primary Osteoblasts Inhibited by IL-1 β through the MEK-Erk1/2 and Jak/Stat3 Pathways
doi: 10.1155/2021/5720145
Figure Lengend Snippet: Effects of GDC0623 and C188-9 on MEK-Erk1/2 and Jak-Stat3 signaling pathways and on expression levels of MMP9 and MMP13. Osteoblasts were pretreated with DMEM plus 0.1% FBS overnight and intervened with IL-1 β , IL-1 β plus GDC0623, and IL-1 β plus C188-9 for 60 min. (a–c) Protein levels of p-Stat3, P-Erk1/2, MMP9, and MMP13 were analyzed after IL-1 β -stimulated osteoblasts had been treated with GDC0623. (d–f) Expression levels of p-Stat3, P-Erk1/2, MMP9, and MMP13 were assessed by blocking the Jak-Stat3 pathway with C188-9.
Article Snippet: To assess protein phosphorylation levels, osteoblasts were cultured in DMEM plus 0.1% FBS overnight and treated with 20 ng/ml IL-1 β (RD company) or IL-1 β plus 0.1 μ M GDC0623 (Selleck, China) or IL-1 β plus 5 μ M C188-9 (Selleck, China) for 60 min.
