Pan-neuronal expression of 5-HT1AScer\UAS.cRa in adult flies (using 31[o]C heat-induced Scer\GAL4nSyb.PS in combination with Scer\GAL80ts.αTub84B) does not significantly affect wall following behavior in an arena (posited measure of anxiety) or walking speed, compared to non-induced (18[o]C) controls.
5HT stimulates fluid secretion in Malpighian tubules isolated from 5-HT1AScer\UAS.cRa; Scer\GAL4c42 or 5-HT1AScer\UAS.cRa; Scer\GAL4tsh-c724 flies. cAMP and CGMP levels are unaffected. The increased fluid scretion is inhibited by yohimbine.
Expression of 5-HT1AScer\UAS.cRa pan-neuronally, under the control of Scer\GAL4elav-C155 restores sleep levels and consolidation in 5-HT1AΔ5kb mutants, with total sleep and night-time sleep bout length increasing while bout number decreases.
Total daily sleep and night-time sleep bout length are restored to wild-type levels in RU486-treated 5-HT1AScer\UAS.cRa mutants, driven with Scer\GAL4Mef2.247.Switch (activated by RU486).
