With the TRPM8 receptor removed, the mouse was unable to detect small changes in temperature and the pain associated with it. [17] Great care should be taken when deciding how to use genetically modified mice in research. [22] Even basic issues like choosing the correct "wild-type" control mouse to use for comparison are sometimes overlooked. [23]
Professor Hanson noted that PEPCK-C mus mice, dubbed "the mighty mice", "are metabolically similar to Lance Armstrong biking up the Pyrenees. They utilize mainly fatty acids for energy and produce very little lactic acid. Without eating or drinking, they can run for four or five hours. They are 10 times more active than ordinary mice in their ...
The upside: your body measurements and body fat percentage will shift. "Your clothes will fit better, you'll notice a change in the mirror, and with a lower body fat percentage, you'll undoubtedly ...
Research shows that up to 60% of the weight loss from prescription medications may come from lean body mass. Muscle loss can affect strength and mobility, so eating enough protein to preserve lean ...
A comparison of a mouse unable to produce leptin thus resulting in obesity (left) and a normal mouse (right). The ob/ob or obese mouse is a mutant mouse that eats excessively due to mutations in the gene responsible for the production of leptin and becomes profoundly obese.
Regardless of your goals, you'll want to be prioritizing protein, too—about 1 gram per pound of your body weight. It will help you build and maintain your muscle mass, and keep you full.
Starvation response in animals (including humans) is a set of adaptive biochemical and physiological changes, triggered by lack of food or extreme weight loss, in which the body seeks to conserve energy by reducing metabolic rate and/or non-resting energy expenditure to prolong survival and preserve body fat and lean mass.
The db/db mouse is a model of obesity, diabetes, and dyslipidemia wherein leptin receptor activity is deficient because the mice are homozygous for a point mutation in the gene for the leptin receptor. [20] In db/db mice, induced swimming helped to overcome obesity by upregulating uncoupling proteins. [21]
