Expression of mus209^GD4205 under the control of Scer\GAL4^c768 results in the gradual loss of neuroepithelium cells of the developing optic lobe during the early to late third larval instar stages and premature neuroblast formation.

Down-regulation of dup in the subperineurial glia, through expression of mus209^GD4205 under the control of Scer\GAL4^moody.PS inhibits DNA replication and reduces polyploidization in subperineurial glia and increases dye penetration around the neuropil and the neuroblasts, indicating increase porosity of the blood-brain barrier in these flies.

Expression under the control of Scer\GAL4¹⁴⁰⁷ results in loss of neuroblasts in the larval brain without any change in size of the remaining neuroblasts.

Expression under the control of Scer\GAL4¹⁴⁰⁷ results in shorter neuroblast lineages (less daughter cells per neuroblast) in the larval brain compared to controls.

Expression under the control of Scer\GAL4¹⁴⁰⁷ results in mild defects in the shape of ganglion mother cells in the larval brain.
