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

      (Aydogan et al., 2018)

      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). The number of mushroom body neuroblasts appears to be increased approximately 5-fold in the mutant compared to wild type. Approximately 10% of homozygous neuroblasts divide symmetrically into two similar-sized daughter cells. Astral microtubules are absent in the mutant neuroblasts.

      17% of homozygous larval brain clones transplanted into the abdomens of wild-type hosts form tumours, proliferating massively and killing the hosts rapidly. 100% of the mutant tissue develops tumours in subsequent rounds of transplantation.

      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.
