OBJECTIVE Streptozotocin (STZ) is the most widely used diabetogenic agent in animal models of islet transplantation. However, the immunomodifying effects of STZ and the ensuing hyperglycemia on lymphocyte subsets, particularly on T regulatory cells (Tregs), remain poorly understood. RESEARCH DESIGN AND METHODS This study evaluated how STZ-induced diabetes affects adaptive immunity and the con...
Objectives: The study is planned to investigate the antidiabetic activity of hesperidin on Streptozotocin (STZ)-induced diabetes mellitus in Swiss Albino mice. Materials and Methods: mice were divided into six groups viz., normal control, diabetic insulin 0.75 IU/kg, 100, 200 400 mg/kg, respectively (n = 6/group). All received treatments once daily for 21 consecutive days, except control groups...
Diabetic bladder dysfunction (DBD) is a common urological complication of diabetes. Innate immune system activation via Toll-like receptor 4 (TLR4) leads to inflammation and oxidative stress and was implicated in diabetes pathophysiology. We hypothesized that bladder hypertrophy and hypercontractility in DBD is mediated by TLR4 activation. Wild-type (WT) and TLR4 knockout (TLR4KO) mice were mad...
Treatment of chloroethylnitrosourea-resistant cells with streptozotocin (STZ) prior to bis-chloroethylnitrosourea (BCNU) exposure has been shown to result in a depletion of O6-methylguanine DNA methyltransferase (MGMT) activity, increased BCNU-induced interstrand cross-linking, and a 2-3 log enhancement of BCNU cytotoxicity in vitro. The current study was undertaken to define the kinetics of re...
The present study investigated the merit of ginseng in the improvement of heart failure in diabetic rats and the role of peroxisome proliferator-activated receptors δ (PPAR δ ). We used streptozotocin-induced diabetic rat (STZ-rat) to screen the effects of ginseng on cardiac performance and PPAR δ expression. Changes of body weight, water intake, and food intake were compared in three groups of...
The fundamental basis of diabetes continues to go unrecognized and untreated. Depending on the type of diabetes i.e; 1 or 2, treatment consists of insulin injections (1) or antidiabetic drugs that lower blood glucose and hopefully hemoglobin A1C as well (2) Often patients with type 2 are asked to lose weight, exercise more vigorously as well and more frequently. Previously, using a diabeticstre...
Diabetes is a growing public health concern, and animal models of this disease are necessary for a full understanding of disease pathogenesis, progression, clinical sequelae, and treatment options. In particular, nonhuman primate models of diabetes are important because of their close genetic relationship to humans. Although numerous Old World primate models have been described, few studies hav...
Non-alcoholic fatty liver disease (NAFLD) is the result of the accumulation of adipose tissue deposits in the liver and it is associated with type 2 diabetes. Crocus sativus (saffron) is known for its antioxidant and its potential hypoglycemic effects. We investigated the role of saffron on NAFLD in diabetic rats. Thirty adult male rats were allocated into three groups; control (n=10), which re...
Diabetic cardiomyopathy includes fibrosis. Kallikrein (KLK) can inhibit collagen synthesis and promote collagen breakdown. We investigated cardiac fibrosis and left ventricular (LV) function in transgenic rats (TGR) expressing the human kallikrein 1 (hKLK1) gene in streptozotocin (STZ) -induced diabetic conditions. Six weeks after STZ injection, LV function was determined in male Sprague-Dawley...
Coffee consumption reduces the risk of type 2 diabetes in humans, but the mechanism remains unclear. In this study, we investigated the effect of coffee on pancreatic β-cells in the induction of diabetes by streptozotocin (STZ) treatment in mice. We examined the effect of coffee, caffeine, or decaffeinated coffee ingestion on STZ-induced hyperglycemia. After STZ injection in Exp. 1 and 2, serum...
