An association between viruses and obesity has been found in humans, as well as a number of different animal species. The amount that these associations may have contributed to the rising rate of obesity is yet to be determined. [5] A fat virus is the popular name for the notion that some forms of obesity in humans and animals have a viral source.
To date, AD-36 is the only human adenovirus that has been linked with human obesity, present in 30% of obese humans and 11% of nonobese humans. [8] In addition, a study of obese Americans indicates that about 30% of the obese individuals and only 5% of non-obese individuals have antibodies to Ad-36. [ 3 ]
In humans, the gene is located on the long arm of chromosome 7 at band 11.2 (7q11.2 [37]) and is encoded by 15 exons that extend over more than 32 kilobases. Both the 5' and the 3' untranslated regions contain introns: the 5' with two and the 3' one. Exons 1, 2 and first 89 nucleotides of exon 3 and as well as exon 15 are non-coding.
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.
Fat mass and obesity-associated protein also known as alpha-ketoglutarate-dependent dioxygenase FTO is an enzyme that in humans is encoded by the FTO gene located on chromosome 16. As one homolog in the AlkB family proteins, it is the first messenger RNA (mRNA) demethylase that has been identified. [ 5 ]
16p11.2 deletion syndrome is a rare genetic condition caused by microdeletion on the short arm of chromosome 16. Most affected individuals experience global developmental delay and intellectual disability, as well as childhood-onset obesity. [1] 16p11.2 deletion is estimated to account for approximately 1% of autism spectrum disorder cases. [3] [4]
Colorado head coach Deion Sanders issued a warning to NFL teams Friday − don’t draft Heisman Trophy winner Travis Hunter if you won’t let him play both ways.. Sanders said this on "The Rich ...
It consists of 22 autosomes plus one copy of the X chromosome and one copy of the Y chromosome. It contains approximately 3.1 billion base pairs (3.1 Gb or 3.1 x 10 9 bp). [ 6 ] This represents the size of a composite genome based on data from multiple individuals but it is a good indication of the typical amount of DNA in a haploid set of ...
