Detailed Description
Statement
Reference

ana2169/ana2719 adults are uncoordinated and fail to perform in climbing assay (negative gravitaxis assay) when compared to controls.

Homozygous larvae have an increased number of neuroblasts in the central brain at 96 hours after larval hatching (approximately 250 neuroblasts compared to approximately 100 neuroblasts in wild-type larvae at this stage).

Homozygous clones in the larval brain result in overgrowth in both type I and type II neuroblast lineages. The number of intermediate neural progenitors (derived from type II neuroblasts in wild type) is also increased.

Homozygous and ana2719/Df(2R)Np3 neuroblasts show severe defects in mitotic spindle orientation. The spindles are not focused at the poles during mitosis.

75% of neuroblasts expressing ana2GD13865 under the control of Scer\GAL4insc-Mz1407 in a ana2719/+ background have a spindle misorientation phenotype.

5% of homozygous larval brain clones transplanted into the abdomens of wild-type hosts form tumours, proliferating massively and killing the hosts rapidly.

Comments

Expression of ana2N1.Scer\UAS.T:Avic\GFP-YFP.Venus under the control of Scer\GAL4insc-Mz1407 almost fully rescues the centrosome assembly and spindle orientation defects of ana2169/ana2719 neuroblasts.

Expression of either ana2C1.Scer\UAS.T:Avic\GFP-YFP.Venus, ana2N2.Scer\UAS.T:Avic\GFP-YFP.Venus or ana2C2.Scer\UAS.T:Avic\GFP-YFP.Venus under the control of Scer\GAL4insc-Mz1407 fails to rescue the spindle orientation defects of ana2169/ana2719 neuroblasts.
