Summarize this passge

The etiology of type 2 diabetes mellitus involves the induction of insulin resistance along with the disruption of pancreatic β-cell function and the loss of β-cell mass. In addition to a genetic predisposition, lifestyle factors seem to have an important role. Epidemiological studies indicate that the increased presence of endocrine disrupting chemicals (EDCs) in the environment may also play an important part in the incidence of metabolic diseases. Widespread EDCs, such as dioxins, pesticides and bisphenol A, cause insulin resistance and alter β-cell function in animal models. These EDCs are present in human blood and can accumulate in and be released from adipocytes. After binding to cellular receptors and other targets, EDCs either imitate or block hormonal responses. Many of them act as estrogens in insulin-sensitive tissues and in β cells, generating a pregnancy-like metabolic state characterized by insulin resistance and hyperinsulinemia. Adult exposure in mice produces insulin resistance and other metabolic alterations; in addition, during pregnancy, EDCs alter glucose metabolism in female mice, as well as glucose homeostasis and endocrine pancreatic function in offspring. Although more experimental work is necessary, evidence already exists to consider exposure to EDCs as a risk factor in the etiology of type 2 diabetes mellitus and other diseases related to insulin resistance.

Homework Answers

Answer #1

The passage describes about the causes of getting type 2 Diabetes. Any alterations in the functions or mass of the pancreatic beta cells along with genetic predisposition,lifestle changes and increased endocrine chemicals in the body due to environmental exposure can lead to insulin resistance and develop type 2 diabetes. The research portrays this EDC will be released from the adipocytes ,altering the hormonal balance .These EDC can act like an estrogen on the insulin sensitive cells and making the individual to experience pregnancy like metabolic state with hyperinsulinemia.In pregnancy it can alter the glucose metabolism and pancreatic function of the growing fetus making them at risk for developing type 2 diabetes.

Summarize this passage. Bisphenol-A (BPA) is a widespread endocrine disruptor that produces insulin resistance and alterations in pancreatic β-cell function [1]. It has been suggested that together with other endocrine disrupting chemicals (EDCs), BPA constitutes a risk factor for type 2 diabetes and other metabolic disorders [2]–[4]. Recent work shows the association between increasing urinary BPA levels and Diabetes Mellitus. A 12.8% of diabetic patients show high BPA levels in urine samples (4.20 ng/ml or 18 nM) [5]. Moreover an...

Prolonged type II diabetes can eventually lead to type I. Place the events leading to this transition into their correct order. (Hint: start with e) (8 points) a) Apoptosis is triggered, β cells die, and insulin secretion ceases. b) The increased levels of ATP resulting from glucose metabolism alter the voltage across the cell membrane. c) Insulin is not utilized correctly by the other cells. d) Ca2+ enters the β cells and triggers the release of insulin. e) Glucose absorption...
