Insulin News and Research

RSS

Insulin is a hormone that is needed to convert glucose, starches and other food into energy needed for daily life. Insulin allows cells to use glucose for fuel and is secreted by beta cells in the islets of Langerhans. The release of insulin from the pancreas is stimulated by increased blood glucose, vagal nerve stimulation, and other factors. Insulin is obtained from various animals and available in a variety of preparations. Commercial insulin preparations differ in a number of ways, including differences in the animal species from which they are obtained; their purity, concentration, and solubility; and the time of onset and duration of their biologic action. An oral hypoglycemic agent is not a form of insulin therapy.

Possible new target for treating obesity and diabetes

The new target, a molecule called hVps34, is activated by amino acids (nutrients) entering the cell. This molecule triggers the activation of an enzyme, S6 Kinase 1 (S6K1), whose function UC researchers linked last year to obesity and insulin resistance.

Human fat cells produce a protein that is linked to both inflammation and an increased risk of heart disease and stroke

Researchers at The University of Texas M. D. Anderson Cancer Center and The University of Texas Health Science Center at Houston have found that human fat cells produce a protein that is linked to both inflammation and an increased risk of heart disease and stroke.

Key cellular switch that controls glucose production in liver cells

In many patients with type 2 diabetes, the liver acts like a sugar factory on overtime, churning out glucose throughout the day, even when blood sugar levels are high. Scientists at the Salk Institute for Biological Studies discovered a key cellular switch that controls glucose production in liver cells.

Low-fat, plant-based diet is more effective at helping women lose weight

A low-fat, plant-based diet is more effective at helping women lose weight and improve insulin sensitivity than an omnivorous diet, shows a new study appearing in the September issue of The American Journal of Medicine.

New ways to enhance or block fertilization

Researchers have capitalized on the unique properties of a sperm cell to follow cell membrane fusion as it occurs during fertilization, tracking the full cascade of events for the first time. The findings could reveal new ways to enhance or block fertilization, as well as how to control the secretion of neurotransmitters and hormones such as insulin.

New tool to help unravel the function of an elusive DNA structure

A Rensselaer researcher has developed a new tool to help unravel the function of an elusive DNA structure. The findings, which were presented today at the 230th national meeting of the American Chemical Society (ACS) in Washington, D.C., could lead to a better understanding of diseases such as cancer and diabetes.

Call for closer examination of a metabolic syndrome

Two major health organizations in Europe and the United States are calling for closer examination of a syndrome that has been widely believed to predict the risk of developing heart disease, questioning whether it has been appropriately defined and whether it is in fact a syndrome at all.

Malfunctioning bone marrow cells cause neuropathy in many people with diabetes

Malfunctioning bone marrow cells that produce insulin appear to cause a dangerous nerve condition called neuropathy that disables many people with diabetes, said a research team led by Baylor College of Medicine (BCM) in Houston.

A cell's energy level is critical to its survival

In an ongoing effort to fight disease by manipulating energy regulation of cells, a collaborative study led by Dartmouth Medical School (DMS) has demonstrated that cells lacking a tumor-suppressing kinase called LKB1 can still maintain healthy energy levels when they become stressed.

Non-invasive imaging may help predict type 1 diabetes and response to treatment in humans

A key obstacle to early detection of type 1 diabetes - as well as to rapid assessment of the effectiveness of therapeutic intervention - has been the lack of direct, non-invasive technologies to visualize inflammation in the pancreas, an early manifestation of disease.

Losing weight cuts breast cancer risk

An international team of scientists has found that young women who carry a breast cancer gene, can reduce their risk of the disease by up to 65% by attaining a healthy bodyweight.

SH2-B enhances brain's leptin sensitivity - may lead to clues for treatment of obesity and diabetes

What do laboratory mice at the University of Michigan Medical School have in common with millions of overweight Americans? Like many of us, these mice just can't stop eating.

Protein Sirt1 points to new therapies for type 2 diabetes

Opening the possibility of new therapies for type 2 diabetes, researchers at Washington University School of Medicine in St. Louis have found that a protein called Sirt1 enhances the secretion of insulin in mice and allows them to better control blood glucose levels. Their study appears in the August 17 issue of Cell Metabolism.

Weight control protein may yield new approaches for treating obesity and type 2 diabetes

The findings in mice further suggest that particular variants of the protein SH2-B might underlie obesity in humans, the researchers said.

Decline in energy production by mitochondria appears to be a key problem leading to insulin resistance

A detectable decline in energy production by mitochondria - the organelles that are the cell's furnace for energy production - seems to be a key problem leading to insulin resistance, and thus to type 2 diabetes, according to studies by Howard Hughes Medical Institute researchers.
