Detailed Description

The expression of Hsap\HTTQ0.UAS under the control of Scer\GAL4P2.4.Pdf does not seem to have a major effect on circadian behavior, nor on the number of sLNv nurons in 10-days old adults.

Expressing Hsap\HTTQ0.UAS under the control of Scer\GAL4GMR.PF induces significant apoptosis (cleaved DCP1 labelling) in the eye disc, as compared to controls.

Adult flies expressing Hsap\HTTQ0.Scer\UAS under the control of the Scer\GAL4P2.4.Pdf driver show robust locomotor activity in constant darkness (DD), with a longer period than in wild-type, which is also observed in the driver line alone. The oscillation of per protein in the somas of l-LNv neurons in DD shows very low amplitude.

Expression of Hsap\HTTQ0.Scer\UAS under the control of Scer\GAL4GMR.PU does not result in eye defects.

When Hsap\HDQ0.Scer\UAS is driven by Scer\GAL4GMR.PF, no eye phenotype is seen. The neurophysiology also appears normal. When Hsap\HDQ0.Scer\UAS is driven by Scer\GAL4elav.PLu or Scer\GAL4elav-C155 no effect is seen in locomotor behaviour or life span.

The co-expression of Hsap\HTTQ0.UAS and Atx2KK100423 under the control of Scer\GAL4P2.4.Pdf leads to a moderate impairment of circadian behavior, as compared to Hsap\HTTQ0.UAS single expression and wild-type controls.

The co-expression of Hsap\HTTQ0.UAS and Atx2ΔLsm.UAS.Tag:FLAG under the control of Scer\GAL4P2.4.Pdf leads to a moderate impairment of circadian behavior, as compared to the Hsap\HTTQ0.UAS single expression and wild-type controls.

The co-expression of Hsap\HTTQ0.UAS and Atx2ΔPAM2.UAS.Tag:FLAG under the control of Scer\GAL4P2.4.Pdf can lead to a moderate impairment of circadian behavior, as compared to the Hsap\HTTQ0.UAS single expression and wild-type controls (this phenotype depends on the Atx2ΔPAM2.UAS.Tag:FLAG insertion).
