Nih Study Shows How Insulin Stimulates Fat Cells To Take In Glucose
Findings could aid in understanding diabetes, related conditions. Using high-resolution microscopy, researchers at the National Institutes of Health have shown how insulin prompts fat cells to take in glucose in a rat model. The findings were reported in the Sept. 8 issue of the journal Cell Metabolism. By studying the surface of healthy, live fat cells in rats, researchers were able to understand the process by which cells take in glucose. Next, they plan to observe the fat cells of people with varying degrees of insulin sensitivity, including insulin resistance — considered a precursor to type 2 diabetes (These observations may help identify the interval when someone becomes at risk for developing diabetes. "What we're doing here is actually trying to understand how glucose transporter proteins called GLUT4 work in normal, insulin-sensitive cells," said Karin G. Stenkula, Ph.D., a researcher at the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) and a lead author of the paper. "With an understanding of how these transporters in fat cells respond to insulin, we could detect the differences between an insulin-sensitive cell and an insulin-resistant cell,

How Is Glucose Stored In The Liver?
The liver is large and in charge. The dark reddish-brown organ sits in the upper right abdomen and, at about 3 pounds, is the largest one inside the body (the skin is the largest organ overall). The liver manages a dizzying array of tasks, including digesting fats, making and storing glucose, and serving as the body's detox center. Glucose Warehouse The liver is an insulin-guided organ: Its behavior changes depending on the level of the hormone insulin in the body and how sensitive the liver is to that insulin. After eating, blood glucose levels rise, which in people without diabetes triggers the pancreas to release insulin into the blood. Insulin is the signal for the body to absorb glucose from the blood. Most cells just use the glucose to supply them with energy. But the liver has a special job when it comes to glucose. When levels of glucose (and consequently insulin) are high in the blood, the liver responds to the insulin by absorbing glucose. It packages the sugar into bundles called glycogen. These glucose granules fill up liver cells, so the liver is like a warehouse for excess glucose. When glucose levels drop, insulin production falls, too. The shortage of insulin in the
In a global first, Australian scientists have figured out the way to reprogram adult bone or fats cells to form stem cells that could doubtlessly regenerate any damaged tissue within the frame. The researchers were stimulated by the manner salamanders are able to update lost limbs, and advanced a technique that gives grownup cells the capacity to lose their person characteristics, multiply and regenerate more than one cell types - what is called multipotency. which means the brand new stem cells can hypothetically repair any injury within the body, from severed spinal cords to joint and muscle degeneration. And its a pretty big deal, because there are currently no person stem cells that certainly regenerate a couple of tissue kinds. "This approach is a massive strengthen on most of the modern-day unproven stem mobile treatment options, that have shown little or no goal evidence they make contributions immediately to new tissue formation," stated lead researcher John Pimanda from the university of recent South Wales, faculty of medication (united states remedy). "we're presently assessing whether or not grownup human fat cells reprogrammed into [induced multipotent stem cells (iMS cells)] can accurately restore broken tissue in mice, with human trials anticipated to begin in past due 2017." proper now, even though its an exciting and plenty-hyped field of look at, stem mobile therapy still has some of boundaries, in general due to the fact the maximum beneficial cells are embryonic stem cells, which can be taken from growing embryos and have the potential to become any cell type within the frame. however in addition they have the tendency to shape tumours and can't be transplanted immediately to regenerate person cells. as a substitute, researchers are able to use tissue-unique person cells, that may simplest change into the cellular types in their vicinity of the body as an instance, lung stem cells can best differentiate into lung tissue, so that theyre now not as versatile as scientists want. Scientists have additionally labored out a way to reprogram ordinary grownup stem cells into caused pluripotent stem cells (iPS) a form of stem cell thats even extra bendy than multipotent stem cells, but requires the usage of viruses in order for the cells to be reset, which isnt perfect to help deal with patients. Thats why the new studies is so interesting. "Embryonic stem cells can't be used to deal with damaged tissues because of their tumour forming capacity," stated one of the researchers, Vashe Chandrakanthan. "the alternative hassle whilst generating stem cells is the requirement to use viruses to transform cells into stem cells, which is clinically unacceptable." "We accept as true with weve overcome these problems with this new method." To create the brand new type of stem cells, the researchers collected grownup human bone and fats cells and treated them with compounds: five-Azacytidine (AZA); and platelet-derived boom component-AB (PDGF-AB) for two days. This kick-started the method of dedifferentiation which basically way it started out to revert them to a multipotent stem cell nation. The cells were then kept in PDGF-AB for a few weeks while they slowly changed into stem cells, subsequently turning into tissue-regenerative iMS cells which basically method they could repair any form of tissue within the body. ; Source: https://www.sciencealert.com/
How Are Carbohydrates Converted Into Fat Deposits?
How are carbohydrates converted into fat deposits? There are two ways that carbohydrates and body fat interact. One is directly by turning into body fat, and the other is via insulin. Turning into body fat is like adding fat into the fat cells, whereas carbohydrates spiking insulin does not add anything to fat cells per se, but hinders the release. The former is like a + equation, where the latter is a double negative which results in something that seems positive. There is a process called de novo lipogenesis (literally: Creation of fat from non-fat sources) that can occur in the body. This process turns glucose into lipids, which are then stored as body fat. This process is normally quite inefficient in the body  , which suggests that carbohydrates cannot be stored as fat to a high degree. The process can be upregulated (enhanced) if dietary fat comprised almost none of the diet (lesser than 10%, as a rough estimate), if carbohydrate intake is excessively high for a period of a few days, or if one follows an obesogenic diet (diet that is likely to make you fat) for a prolonged period of time.    Carbohydrates spike insulin , which is a hormone that mediates glucose m
Carbs and carbs alone, not fat, increase body weight. It doesn't matter whether the carbs are from sugar, bread, fruit, or vegetables: They’re all rapidly digested and quickly converted to blood glucose. A short time after a carb-rich meal, the glucose in your bloodstream rises rapidly, and your pancreas produces a large amount of insulin to take the excess glucose out. Just as eating fat doesn’t raise blood glucose, it doesn't raise insulin ...
Your body uses mostly carbohydrates as well as fats for energy. Because the body doesn’t store carbs efficiently, they’re used first. Carbohydrates turn into glucose, which your body burns immediately or converts to glycogen to be stored in the muscles and liver for between meals. If you eat more calories from carbs or other sources than your body can use, the cells store the excess as fat. Of the three major nutrients -- carbohydrates, fat a ...
All parts of the body (muscles, brain, heart, and liver) need energy to work. This energy comes from the food we eat. Our bodies digest the food we eat by mixing it with fluids (acids and enzymes) in the stomach. When the stomach digests food, the carbohydrate (sugars and starches) in the food breaks down into another type of sugar, called glucose. The stomach and small intestines absorb the glucose and then release it into the bloodstream. Once ...

Consumers are inundated with diet solutions on a daily basis. High protein, low fat, non-impact carbohydrates, and other marketing “adjectives” are abundant within food manufacturing advertising. Of all the food descriptors, the most common ones individuals look for are “fat free” or “low fat”. Food and snack companies have found the low fat food market to be financially lucrative. The tie between fat intake, weight gain, and health r ...
Eating a diet high in simple carbohydrates can raise your level of triglycerides—fats carried in the blood and stored in fat cells. The body turns carbohydrates into glucose to use for fuel, but will store excess glucose as fat. High levels of triglycerides can increase your risk for heart disease. Triglycerides are fats. You eat triglycerides in the form of foods such as butters and oil, but your body also makes triglycerides from excess calor ...
