Abstract:
Objective: To investigate the effects of 25-hydroxyvitamin D3[25(OH) D3,D3] on NLRP3 inflammasome activation and inflammatory response of bone marrow mesenchymal stem cells (BMSCs) from diabetic rats. Methods: BMSCs were isolated from diabetic rats and identified by immunocytochemical staining. The cells were divided into diabetic control group (without D3 treatment),low concentration group(treated with 1 × 10-5 mmol /L of D3),intermediate concentration group(treated with 1 × 10-4 mmol /L of D3),and high concentration group(treated with 1 × 10-3 mmol /L of D3) (n = 10),BMSCs from normal rats were used as the normal control group(without D3 treatment). Inflammation-related proteins including NLRP3 in BMSCs were examined by western blot analysis. Results: The cultured cells expressed biomarkers of BMSCs. VDR expression in normal control,diabetic control and low concentration groups was less than that in intermediate concentration and high concentration groups(P < 0. 05). Compared with all diabetc groups,normal control group expressed less NF-κB,NLRP3,ASC,Caspase-1,IL-1β,IL-18 and IL-6(P < 0. 05). Additionally,diabetic control and low concentration groups showed stronger expression of NF-κB,NLRP3,ASC,Caspase-1,IL-1β,IL-18 and IL-6 than intermediate concentration and high concentration groups(P < 0. 05). Conclusion: 25-(OH)2-D3 can inhibit the activation of NLRP3 in BMSCs and suppress the inflammatory response of BMSCs from the diabetic rats.
