The effect of leaf extract P.harmala on streptozotocin-induced apoptosis in pancreatic tissue of rats
Abstract Background and Purpose: Decreased beta-cell mass has a role in the pathogenesis of human type 2 diabetes and in rodent diabetes models. The study of plant extracts is important as they possibly inhibit the reduction of beta cell mass and the islets of Langerhans. The effect of the methanolic extract of P. harmala leaves on pancreatic tissue was investigated in this research. Method: A ...
متن کاملGestational diabetes leads to down-regulation of CDK4-pRB-E2F1 pathway genes in pancreatic islets of rat offspring
Objective(s): The link between a hyperglycemic intrauterine environment and the development of diabetes later in life has been observed in offspring exposed to gestational diabetes mellitus (GDM), but the underlying mechanisms for this phenomenon are still not clear. Reduced β-cells mass is a determinant in the development of diabetes (type 1 and type 2 diabetes). Some recent studies have provi...
متن کاملFailure of beta-cell adaptation in type 2 diabetes: Lessons from animal models.
The pancreatic beta-cell adapts to increased nutrient availability and insulin resistance by increasing its function and mass. These processes are orchestrated by signals derived from nutrient metabolism, hormones and cytokines. Their end-result is the regulation of insulin secretion and biosynthesis, and beta-cell proliferation and apoptosis. This review focuses on the mechanisms involved in b...
متن کاملبررسی القای تمایز سلولهای بنیادی به سلولهای بتای پانکراس بهوسیله عصاره متانولی یونجه
Background and Objective: β cell replacement therapy by pancreatic islet transplantation has become a promising treatment for type 1 diabetes. Medicago sativa L (Lucerne) from leguminosae family is known to exhibit hypoglycaemic activity both in animal and human studies. Most of these studies were concentrated on the effects of plant extracts on fasting glucose levels. Until now no researches h...
متن کاملConsequences of fetal exposure to maternal diabetes in offspring.
CONTEXT Type 2 diabetes is the result of both genetic and environmental factors. Fetal exposure to maternal diabetes is associated with a higher risk of abnormal glucose homeostasis in offspring beyond that attributable to genetic factors, and therefore, may participate in the excess of maternal transmission of type 2 diabetes. EVIDENCE ACQUISITION A MEDLINE search covered the period from 196...
