摘要：Osteoarthritis (OA) pathogenesis involves inflammation, age, weight and other factors. Integrin-linked kinase (ILK) regulates cell apoptosis, metastasis, and growth. However, whether ILK affects bone formation of bone marrow mesenchymal stem cells in an inflammatory environment has not been elucidated. Rat BMSCs were isolated and assigned into control group, inflammation group (lipopolysaccharide was added to cells); and si-ILK group (ILK siRNA was transfected into the inflammation group BMSCs) followed by analysis of cell proliferation by MTT assay, expression of ILK, Runx2 and OP by real time PCR, ALP activity, TNF-alpha and IL-6 secretion by ELISA and MAPK/AKT signaling protein expression by western blot. Compared to control, ILK in BMSCs cells in inflammatory environment was significantly upregulated, resulting in inhibition of cell proliferation, decreased ALP activity, reduced expression of osteogenic genes Runx2 and OP, increased secretion of TNF-alpha and IL-6, and downregulated p-AKT (P < 0.05); transfection of ILK siRNA downregulated ILK in inflammatory environment BMSCs, which significantly increased BMSCs cell proliferation, increased ALP activity and expression of Runx2 and OP, decreased TNF-alpha and IL-6 secretion and increased p-AKT expression (P < 0.05). ILK expression is increased in BMSCs in an inflammatory environment. Down-regulation of ILK in BMSCs cells in an inflammatory environment can regulate MAPK/AKT signaling, inhibit inflammatory factors secretion, thereby promoting BMSCs proliferation and osteogenesis differentiation.
