In this study, we investigated the anti-inflammatory effect of genistein on the pancreatic β-cells in ovariectomized diabetic rat. Materials and Methods:Forty female rats were divided into four groups: sham, bilateral ovariectomy (OVX), OVX.D (OVX+diabetes) and OVX.D.G (OVX.D+genistein). After bilateral ovariectomy, rats in the diabetic groups were fed high-fat diet (HFD), ad libitum for 4 weeks, and then a low dose of streptozotocin (STZ) (30 mg/kg) injected intraperitoneally. Genistein (1 mg/kg/day; SC) was administrated for 8 weeks. At the end of 8 weeks, pancreas tissue was removed and used for western blotting and Hematoxylin-Eosin staining. Results: Treatment with genistein declined inflammation and tissue injury, and this decline was correlated with the expression of SIRT1. OVX and OVX.D significantly increased Nf-кB and IL-1β expression and decreased SIRT1 levels compared to sham group (P<0.05). Significant reduction of Nf-кB and IL-1β, and increasing of SIRT1 were observed during genistein treatment (P<0.05). Conclusion: Estrogen deficiency alone or with HFD increased pancreatic inflammation. However, subcutaneous administration of gtenistein prevented from these inflammatory changes in the pancreas of a surgery animal model of ovariectomy with or without diabetes. Our results support the potential preventing effect of genistein from pancreatic injury.}, keywords = {Diabetes,Genistein,Inflammatory cytokines-ovariectomy,SIRT1}, url = {https://ijbms.mums.ac.ir/article_8585.html}, eprint = {https://ijbms.mums.ac.ir/article_8585_7f7493ee63a8324631016b4c678fa836.pdf} }
