The role of SNORD116 in the neuroendocrine phenotypes of Prader-Willi syndrome

A hallmark symptom of PWS is extreme, unrelenting hyperphagia associated with obesity. Other medical characteristics of individuals with PWS include low circulating growth hormone, short stature, adrenal insufficiency, hypothyroidism, and hypogonadism. Additionally, individuals with PWS have decreased levels of circulating fasting insulin...

Regulation of ghrelin and serotonin receptors by SNORD115

The loss of two regulatory RNAs is critical for the development of Prader-Willi syndrome. One of these RNAs prevents the formation of a truncated serotonin receptor. We will test the role of this truncated serotonin receptor in the production...
