A Brief Note On Prader Willi Syndrome - www.informationsecuritysummit.org

Researchers with the UC Davis MIND Institute and Agilent Laboratories have found that Prader-Willi syndrome — a genetic disorder best known for causing an insatiable appetite that can lead to morbid obesity — is associated with the loss of non-coding RNAs, resulting in the dysregulation of circadian and metabolic genes, accelerated energy expenditure and metabolic differences during sleep.

It is published online in Human Molecular Genetics. The finding could have a profound effect on how clinicians treat children with Prader-Willi, as well as point the way to new, innovative therapies, LaSalle said. The leading cause of morbid obesity among children in the United States, Prader-Willi involves a complex, and sometimes contradictory, array of symptoms. Shortly after birth children with Prader-Willi experience failure to thrive. Yet after they begin to feed themselves, they have difficulty sleeping and insatiable appetites that lead to obesity if their diets are not carefully monitored.

The current study was conducted in a mouse model of Prader-Willi syndrome.

It found that mice engineered with the loss of a long non-coding RNA showed altered energy use and metabolic differences during sleep. The HG long non-coding RNA forms a cloud inside neuronal nuclei that associates with proteins and genes regulating diurnal metabolism in the brain, LaSalle said.

This long non-coding RNA was acting as a decoy, pulling the active transcription A Brief Note On Prader Willi Syndrome away from genes and keeping them from being expressed. This underlies a complex cycle in which the RNA cloud grew during sleep periods daytime for nocturnal miceturning down genes associated with energy use, and receded during waking periods, allowing these genes to be expressed. Mice without the HG gene lacked the benefit of this neuronal cloud, causing greater energy expenditure during sleep.

For example, many such children have been treated with growth hormone because of short stature, but this actually may boost other aspects of the disease. If you can work with that, you could improve therapies, for example figuring out the best times to administer medications.
