indian traditional system of medicine has been used plants and herbs for treatment of diabetes since time of vedic glory. in this regard many plants still untouched, having remarkable efficacy. the blood sugar lowering effect of 95% ethanolic extract of c. tamala ( hamm.) nees. & eberm., leaves was investigated at single oral dose of 250mg/kg body weight in normal fasted, fed, glucose loaded an...

Type 1 diabetes (T1D) is caused by dysregulation of the immune system in the pancreatic islets, which eventually leads to insulin-producing pancreatic β-cell death and destabilization of glucose homeostasis. One of the major characteristics of T1D pathogenesis is the production of inflammatory mediators by macrophages that result in destruction or damage of pancreatic β-cells. In this study the...

Newly generated insulin-secreting cells for use in cell therapy for insulin-deficient diabetes mellitus require properties similar to those of native pancreatic β-cells. Pancreatic β-cells are highly specialized cells that produce a large amount of insulin, and secrete insulin in a regulated manner in response to glucose and other stimuli. It is not yet explained how the β-cells acquire this co...

UNLABELLED Transforming growth factor (TGF)-β induces epithelial-mesenchymal transition (EMT) in pancreatic adenocarcinoma. In this study, we investigated how NADPH oxidase (Nox) 4-generated reactive oxygen species (ROS) regulate TGF-β-induced EMT in pancreatic cancer cells. MATERIALS AND METHODS Pancreatic cancer cells were transfected with Nox4 siRNAs or PTP1B mutants and subjected to TGF-β...

Replenishing insulin-producing pancreatic β cell mass will benefit both type I and type II diabetics. In adults, pancreatic β cells are generated primarily by self-duplication. We report on a mouse model of insulin resistance that induces dramatic pancreatic β cell proliferation and β cell mass expansion. Using this model, we identify a hormone, betatrophin, that is primarily expressed in liver...

β-Cell dysfunction in diabetes results from abnormalities of insulin production, secretion, and cell number. These abnormalities may partly arise from altered developmental programming of β-cells. Foxo1 is important to maintain adult β-cells, but little is known about its role in pancreatic progenitor cells as determinants of future β-cell function. We addressed this question by generating an a...

Autoimmune type 1 diabetes (T1D) development results from the interaction between pancreatic β-cells, and the innate and the adaptive immune systems culminating with the destruction of the insulin-secreting β-cells by autoreactive T cells. This diabetogenic course starts during the first postnatal weeks by the infiltration of the pancreatic islets by innate immune cells and particularly neutrop...

Objectives: This study investigates the effects of hydro-alcoholic extract of Prangos ferulacea (L.) Lindle (P.f) on rats' pancreas structure changes and diabetic treatment after streptozotocin injection. Materials and Methods: In this research forty male Wistar rats with body weights of 100±20 gram, were randomly divided into 5 groups with 8 rats per each group. Diabetes was induced in rats b...

Objective(s): Diabetes is a metabolic syndrome which is associated with the worldwide major public health problems. There are many natural compounds from the sea-market, as a valuable aquatic source, along with the variety of health and therapeutic benefits. In the present research, with respect to the traditional and ethnic uses of Sargassum oligocystum algae for healing of some diseases which...
