Description

UAS regulatory sequences drive expression of the Hsap\MAPT 2N4R isoform (2 N terminal domains and 4 R-repeats, 441aa). The ORF was codon-optimised for Drosophila expression and a 'Cavener start-ATG' was added to the 5' end.

Detailed Description
Statement

Expression of Hsap\MAPTScer\UAS.2N4R.cFa driven by Scer\GAL4nSyb.PS leads to significantly reduced adult lifespan relative to controls, no significant effect on adult survival is observed when the expression is limited to adulthood by using tub-Gal80[ts].

Flies expressing Hsap\MAPTScer\UAS.2N4R.cFa under the control of Scer\GAL4VGlut-OK371 show no climbing ability defects early on but they display a slight locomotion deficit at day 14 relative to age-matched controls.

The reduced adult lifespan characteristic for flies expressing Hsap\TTBK2Scer\UAS.T:Hsap\MYC,T:Ivir\HA1 under the control of Scer\GAL4nSyb.PS combined with tub-Gal80[ts] to limit the expression to adulthood as well as the adult locomotion deficit (climbing ability defects is further decreased by co-expression of Hsap\MAPTScer\UAS.2N4R.cFa.

Hsap\TTBK1Scer\UAS.T:Hsap\MYC,T:Ivir\HA1, Hsap\TTBK2Scer\UAS.T:Hsap\MYC,T:Ivir\HA1, Hsap\MAPTScer\UAS.2N4R.cFa and Hsap\MARK1Scer\UAS.T:Hsap\MYC,T:Ivir\HA1 expressed under the control of Scer\GAL4nSyb.PS combined with tub-Gal80[ts] to limit the expression to adulthood show combinatorial toxicity and lead to short adult lifespan. The short lifespan of adults expressing any two of the above mentioned transgenes is reduced even further when a third one is added, except for simultaneous expression of Hsap\TTBK1Scer\UAS.T:Hsap\MYC,T:Ivir\HA1 and Hsap\TTBK2Scer\UAS.T:Hsap\MYC,T:Ivir\HA1 where the combination with Hsap\MAPTScer\UAS.2N4R.cFa partially alleviates the reduced survival. When Hsap\TTBK1Scer\UAS.T:Hsap\MYC,T:Ivir\HA1, Hsap\TTBK2Scer\UAS.T:Hsap\MYC,T:Ivir\HA1, and Hsap\MARK1Scer\UAS.T:Hsap\MYC,T:Ivir\HA1 are co-expressed, the addition of Hsap\MAPTScer\UAS.2N4R.cFa cannot further shorten the adult lifespan.

Adult flies co-expressing both Hsap\MARK1Scer\UAS.T:Hsap\MYC,T:Ivir\HA1 and Hsap\MAPTScer\UAS.2N4R.cFa under the control of Scer\GAL4nSyb.PS combined with tub-Gal80[ts] to limit the expression to adulthood show significantly reduced lifespan relative to controls. Similarly, flies simultaneously expressing both these transgenes under the Scer\GAL4VGlut-OK371 driver display age-progressive locomotion deficit (climbing ability defects) that start to be apparent at day 7 post-eclosion.
