Like many other medical conditions, obesity is the result of an interplay between environmental and genetic factors. [2] [3] Studies have identified variants in several genes that may contribute to weight gain and body fat distribution, although only in a few cases are genes the primary cause of obesity. [4] [5]
Numerous studies aimed to provide insight into genetic, economic, and/or environmental causes of obesity. According to the "thrifty gene hypothesis, [18] a genetic theory explaining rising obesity rates, certain individuals are genetically predisposed to metabolize food more efficiently than others as a result of human evolution. In times of ...
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. It is an animal model of type II diabetes.
Obesity isn’t just a matter of food and exercise — it may be in your genetic code, according to new research. “Obesity’s causes are very complex and in the majority of cases, the ...
Scientists have found that people missing a specific blood group due to a genetic variant may be genetically predisposed to having obesity or ... 21 genes related to Alzheimer’s disease to obesity.
FTO has been demonstrated to efficiently demethylate the related modified ribonucleotide, N6,2'-O-dimethyladenosine, and to an equal or lesser extent, m 6 A, in vitro . [5] [15] FTO knockdown with siRNA led to increased amounts of m 6 A in polyA-RNA, whereas overexpression of FTO resulted in decreased amounts of m 6 A in human cells. [10]
Some people’s genetics predispose them to obesity. But nature is not destiny. Here are five tips for losing weight.
The main problem with this idea is the timing at which the transition is presumed to have happened, and how this would then translate into the genetic predisposition to type 2 diabetes and obesity [citation needed]. For example, the decline in reproductive investment in human societies (the so-called r to K shift) has occurred far too recently ...
