Furthermore, treatment with CGA also upregulated the phosphorylation of extracellular signal‑regulated kinase (Erk) and inhibited the adipocyte differentiation of BMSCs by inhibiting the expression of peroxisome proliferator‑activated receptor (PPAR)γ and CCAAT/enhancer binding protein (C/EBP)α.  Furthermore, CGA treatment upregulated Erk phosphorylation and decreased the expression levels of PPARγ and CEBPα, which was inhibited by treatment with the Shp2 PTPase activity inhibitor, NSC‑87877.
