hide Detailed Description
Statement
Reference
Expression of Hsap\BACE1[Scer\UAS.cGa] in photoreceptor neurons under the control of Scer\GAL4[elav-C155] results in the degeneration of the highly organised architecture of retinal photoreceptors in an age-dependent manner.
Expression of Hsap\BACE1Scer\UAS.cGa in eyes under the control of Scer\GAL4GMR.PF does not cause retinal degeneration.

Co-expression of Hsap\BACE1[Scer\UAS.cGa] suppresses the increase in vacuolisation seen when Hsap\APP[695.Scer\UAS.Exel] is expressed in the brains of SNF4Aγ[loe] mutant third instar larvae under the control of Scer\GAL4[Appl.G1a].
Forced expression of Ide[Scer\UAS.cTa] under the control of Scer\GAL4[elav-C155] can suppress the neuronal degeneration induced by the expression of Hsap\BACE1[Scer\UAS.cGa]. Forced expression of Hsap\IDE[Scer\UAS.cTa] under the control of Scer\GAL4[elav-C155] can suppress the neuronal degeneration induced by the expression of Hsap\BACE1[Scer\UAS.cGa]. Co-expression of Hsap\BACE1[Scer\UAS.cGa] and Hsap\APP[695.Scer\UAS] under the control of Scer\GAL4[elav-C155] results in reduced lifespan compared with controls. The reduced lifespan of flies co-expressing Hsap\BACE1[Scer\UAS.cGa] and Hsap\APP[695.Scer\UAS] under the control of Scer\GAL4[elav-C155] is partially suppressed by the co-expression of Ide[Scer\UAS.cTa]. The reduced lifespan of flies co-expressing Hsap\BACE1[Scer\UAS.cGa] and Hsap\APP[695.Scer\UAS] under the control of Scer\GAL4[elav-C155] is partially suppressed by the co-expression of Hsap\IDE[Scer\UAS.cTa]. The ectopic wing vein phenotype induced by co-expressing Hsap\BACE1[Scer\UAS.cGa] and Hsap\APP[695.Scer\UAS] under the control of Scer\GAL4[Act5C.PI] is suppressed by the co-expression of Ide[Scer\UAS.cTa]. The ectopic wing vein phenotype induced by co-expressing Hsap\BACE1[Scer\UAS.cGa] and Hsap\APP[695.Scer\UAS] under the control of Scer\GAL4[Act5C.PI] is suppressed by the co-expression of Hsap\IDE[Scer\UAS.cTa].
The survival rates and wing patterns are not affected when flies coexpress Psn+14.Scer\UAS and Hsap\BACE1Scer\UAS.cGa under the control of Scer\GAL4Act5C.PI. Coexpression of Hsap\BACE1Scer\UAS.cGa and Hsap\APP695.Scer\UAS, under the control of Scer\GAL4GMR.PF, leads to a retinal degeneration phenotype that is less severe than that seen when Hsap\APP695.Scer\UAS is expressed alone. Flies that coexpress Hsap\APP695.Scer\UAS and Hsap\BACE1Scer\UAS.cGa under the control of Scer\GAL4Act5C.PI exhibit ectopic wing veins. This phenotype is enhanced in flies that express Psn+14.Scer\UAS in addition to Hsap\APP695.Scer\UAS and Hsap\BACE1Scer\UAS.cGa under the control of Scer\GAL4Act5C.PI. A PsnC4/+ background partially rescues the ectopic wing vein formation and semi-lethality of flies that coexpress Hsap\APP695.Scer\UAS and Hsap\BACE1Scer\UAS.cGa under the control of Scer\GAL4Act5C.PI.
