摘要

Sleep homeostasis is crucial for sleep regulation. The role of epigenetic regulation in sleep homeostasis is unestablished. Previous studies showed that octopamine is important for sleep homeostasis. However, the regulatory mechanism of octopamine reception in sleep is unknown. In this study, we identify an epigenetic regulatory cascade (Stuxnet-Polycomb-Oct beta 2R) that modulates the octopamine receptor in Drosophila. We demonstrate that stuxnet positively regulates Oct beta 2R through repression of Polycomb in the ellipsoid body of the adult fly brain and that Oct beta 2R is one of the major receptors mediating octopamine function in sleep homeostasis. In response to octopamine, Oct beta 2R transcription is inhibited as a result of stuxnet downregulation. This feedback through the Stuxnet-Polycomb-Oct beta 2R cascade is crucial for sleep homeostasis regulation. This study demonstrates a Stuxnet-Polycomb-Oct beta 2R-mediated epigenetic regulatory mechanism for octopamine reception, thus providing an example of epigenetic regulation of sleep homeostasis.
