Cytology

Description

141bp spanning the mir-1000 hairpin has been deleted. A pair of inverted attP sites surrounding a single loxP site are present at the site of the deletion. Expression of the msi gene (mir-1000 is located within an intron of msi) is unaffected.

Detailed Description

Statement

Reference

mir-1000^KO1/mir-1000^KO2 and mir-1000^KO2/Df(3R)Exel6203 adults show a sharply reduced lifespan, with survival declining rapidly by 2 weeks of age. mir-1000^KO1/mir-1000^KO2 adults show a progressive decline in climbing ability, with significant defects already seen at 2 days of age. Caspase-3 positive cells are seen in the brains of 2 and 10 day old mir-1000^KO1/mir-1000^KO2 adults and vacuoles are seen in 10 day old brains.

mir-1000^KO1/mir-1000^KO2 adults show reduced survival on exposure to hydrogen peroxide compared to controls.

Two day old mir-1000^KO2/mir-1000^KO2-GAL4 adults show a defect in climbing ability.

Statement

Reference

Expression of Diap1^Scer\UAS.cUa under the control of Scer\GAL4^mGluR-NP6701 partially suppresses the short lived phenotype of mir-1000^KO1/mir-1000^KO2 adults and reduces the number of Caspase-3 positive cells seen in the adult brain of these flies. The climbing defects are also rescued.

The climbing defects of two day old mir-1000^KO2/mir-1000^KO2-GAL4 adults are rescued by expression of VGlut^GD834 under the control of Scer\GAL4^{mir-1000-KO2-GAL4}. The amount of Caspase-3 positive cells in the brain is reduced, and lifespan is increased (although not to control levels).

The climbing defects of two day old mir-1000^KO1/mir-1000^KO2 adults are rescued if they are also carrying Df(2L)BSC37/+. The amount of Caspase-3 positive cells in the brain is reduced, and lifespan is increased (although not to control levels).

The climbing defects of mir-1000^KO1/mir-1000^KO2 adults are rescued if they are also carrying Nmdar1^EP331/+, and lifespan is increased (although not to control levels).

The climbing defects of mir-1000^KO1/mir-1000^KO2 adults are rescued if they are also carrying GluRIA^f05411/+, and lifespan is increased (although not to control levels).

The climbing defects and shortened lifespan of mir-1000^KO1/mir-1000^KO2 adults are rescued if they are also carrying mGluR^MI02169/+.

The climbing defects and shortened lifespan of mir-1000^KO1/mir-1000^KO2 adults are rescued if they are also carrying mGluR^GD707.

The climbing defects of mir-1000^KO1/mir-1000^KO2 adults are not rescued by Df(2L)Exel8016/+.
