Fig. 2From: Curcumin induces regeneration of β cells and suppression of phosphorylated-NF-κB in streptozotocin-induced diabetic miceExpression of insulin and phosphorylated-NF-κB by immunohistochemistry. Photomicrographs of pancreatic islets stained with positive brown color for anti-insulin (a–f) and anti-p-NF-κB antibodies (g–l) in CD1 mice. Group I, normal mice; group II, mice treated with citrate; group III, mice treated with DMSO; group IV, mice treated with curcumin at a dose of 170 mg/kg; group V, diabetic mice induced by injection with 160 mg/kg of STZ; group VI, diabetic mice treated with curcumin with a dose of 170 mg/kg. Magnification is × 400. p-NF-κB, phosphorylated-NF-κBBack to article page
