FIGURE 5.

Expression of AKT, mTOR, and S6 ribosomal protein in the human gingival tissues of patients with periodontitis and LPS‐stimulated HGFs. (A) Protein levels of AKT and S6 ribosomal protein were analyzed in the healthy gingival tissues (control) or the gingival tissues of patients with periodontitis via Western blot analysis. (B) The phosphorylation of AKT, mTOR, and S6 ribosomal protein in the LPS‐treated HGFs was detected by Western blot analysis. Each protein was quantitated by densitometry and normalized to β‐actin. AKT, protein kinase B; HGFs, human gingival fibroblasts; LPS, lipopolysaccharide; S6, protein S6K1. **p < 0.01 vs. control
