The insulin signalling pathway
A significant stress faced by all animals is the unpredictable cycle of feeding and then starvation that ensues between meals. Humans solve this problem by storing nutrients in forms that can be used as energy sources during periods of fasting. The driving force that regulates this process is insulin, a hormone released by the β-pancreatic islet cells in response to elevated levels of nutrients...
متن کاملhedgehog signalling pathway: carcinogenesis and targeted therapy
hedgehog signalling pathway has not only a critical role in cell proliferation, differentiation and tissue polarity at embryonic period but also has a vital role in stem cell proliferation, tissue healing and carcinogenesis. recent research has increased our understanding of this pathway and its relation to other signalling pathways. in addition, a large number of studies confirmed the alterati...
متن کاملDeficient brain insulin signalling pathway in Alzheimer's disease and diabetes.
Brain glucose metabolism is impaired in Alzheimer's disease (AD), the most common form of dementia. Type 2 diabetes mellitus (T2DM) is reported to increase the risk for dementia, including AD, but the underlying mechanism is not understood. Here, we investigated the brain insulin-PI3K-AKT signalling pathway in the autopsied frontal cortices from nine AD, 10 T2DM, eight T2DM-AD and seven control...
متن کاملInsulin signalling in the heart.
The main role of insulin in the heart under physiological conditions is obviously the regulation of substrate utilization. Indeed, insulin promotes glucose uptake and its utilization via glycolysis. In addition, insulin participates in the regulation of long-chain fatty acid uptake, protein synthesis, and vascular tonicity. Significant advancements have been made over the last 20 years in the u...
متن کاملComparison of the mammalian insulin signalling pathway to invertebrates in the context of FOXO-mediated ageing
MOTIVATION A large number of experimental studies on ageing focus on the effects of genetic perturbations of the insulin/insulin-like growth factor signalling pathway (IIS) on lifespan. Short-lived invertebrate laboratory model organisms are extensively used to quickly identify ageing-related genes and pathways. It is important to extrapolate this knowledge to longer lived mammalian organisms, ...
