A new study from the University of Illinois found that cytokine resistance contributes to the pathology of type 2 diabetes by impairing the anti-inflammatory response and disrupting insulin-like signaling pathways. This impairment leads to chronic inflammation, which exacerbates health issues in individuals with obesity or diabetes.
Researchers at Salk Institute discover critical gene PHA-4 that specifically links calorie restriction to increased longevity in mice and other species. This breakthrough opens the door to developing drugs that mimic calorie restriction's effects, potentially allowing people to reap health benefits without adhering to an austere regimen.
Researchers at NYU and Scripps have identified a new enzyme GAPDH that regulates insulin pathways, providing a promising direction for treating diabetes. The discovery of GAPDS, an inhibitor of GAPDH, attenuates diabetic symptoms in model animals, suggesting a potential therapeutic target.
Researchers found that mice lacking pancreatic beta cell M3 receptors developed impaired glucose tolerance and reduced insulin release. In contrast, mice with increased M3 receptors showed improved glucose tolerance and insulin release, becoming resistant to developing symptoms of diabetes.
Researchers identified a protein, Smk-1, that regulates longevity in Caenorhabditis elegans without affecting other insulin signaling pathway functions. This finding raises the prospect of medically tweaking this pathway to slow aging and improve quality of life.
University of Washington researchers found a gland in fruit flies that assesses the fly's size and sends hormonal signals to initiate metamorphosis. By genetically manipulating the prothoracic gland, scientists could alter the size at which the fly would reach adulthood, providing new insights into an organism's growth process.
The study found that SOCS-7-deficient mice have increased IRS protein levels and prolonged IRS activation, leading to enhanced insulin action and glucose homeostasis. The researchers also observed increased growth of pancreatic islets with elevated fasting insulin levels and hypoglycemia.
A new mouse model has shown reduced blood glucose levels and lower serum insulin, indicating improved glucose tolerance in the liver. The study found that Gab1 acts as a negative regulator on insulin signal strength in the liver, suggesting potential therapeutic targets for type 2 diabetes.
Researchers at Joslin Diabetes Center have identified the critical role of two insulin signaling proteins in controlling glucose and lipid metabolism. By knocking out these proteins in liver cells, they found that diabetes results when both signals are simultaneously low, but not when either is individually depleted.
Researchers found that reducing insulin-like molecules in fruit fly brains increases the intoxicating effect of alcohol, mimicking human vulnerabilities. Insulin regulates behavior and may be crucial in determining response to addictive drugs, offering potential therapy for alcoholism.
Dr. C. Ronald Kahn receives the award for his groundbreaking work on insulin signal transduction and its link to diseases like diabetes, Alzheimer's, and obesity.
A study published in Nature reveals that insulin regulates tissue aging and extends the lifespan of genetically modified flies. By blocking insulin's action in specific cells, the entire body stays healthier longer, staving off age-related diseases.
Understanding insulin-regulatory pathways is crucial to identifying health-enhancing and disease-endangering manipulations. Research has identified components of key insulin-controlled signaling pathways, including IRS1 and IRS2, which regulate body growth, glucose homeostasis, and female fertility.
Researchers at UT Southwestern Medical Center have found that insulin family signaling plays a critical role in male sex determination. The discovery furthers the understanding of testes formation and may lead to new treatments for reproductive disorders. Insulin-like genes, including Insl3, also play a key role in this process.
Researchers found that FOXO plays a role in reducing the number of cells in developing fruit flies when insulin signalling is not present. This suggests that FOXO inhibits cell division to control body size.
Researchers found that extra sugar on proteins can cause insulin resistance in cells. The discovery provides a potential target for developing new strategies to treat or prevent diabetes.
Researchers at the University of Pennsylvania School of Medicine have discovered a key step in regulating PPAR-gamma receptors, which control insulin sensitivity. The finding may lead to drugs with fewer side effects and greater efficiency for treating adult-onset diabetes.
A team of Australian scientists has made a world-first discovery by describing the structure of a vital receptor found on the surface of body cells in all animals, including humans. This breakthrough has major implications for understanding growth and development, as well as diseases such as diabetes and cancer.
