The T1 and T2 segments of stage 16 embryos expressing aseUAS.Tag:MYC under the control of Scer\GAL4elav-C155 do not show significant changes in the numbers of dividing neuroblasts and dividing neuroblast daughters, as compared to controls.
Scer\GAL4da.G32, SoxNUAS.Tag:V5, aseUAS.Tag:MYC, worUAS.Tag:FLAG has embryonic neuroblast | embryonic stage 12 phenotype
At stage 11 combinatorial expression of aseUAS.Tag:MYC, worUAS.Tag:FLAG, SoxNUAS.Tag:V5 and KrUAS.Tag:V5 under the control of Scer\GAL4da.G32 leads to extensive ectopic neuroblasts not only in the underlying cell layers, but also in the upper neuroectodermal layer when compared to control embryos.
The triple co-expression of aseUAS.Tag:MYC, worUAS.Tag:FLAG and SoxNUAS.Tag:V5, or quadruple co-expression with KrUAS.Tag:V5, under the control of Scer\GAL4da.G32 triggers additional neuroblast and extensive over-proliferation in stage 12 embryos, as compared to controls. Quadruple expression under the control of Scer\GAL4lbe.K leads to the expansion of the NB5-6 neuronal lineage in late embryos, as compared to controls.
The sextuple co-expression of aseUAS.Tag:MYC, worUAS.Tag:FLAG, SoxNUAS.Tag:V5, KrUAS.Tag:V5, hbUAS.Tag:MYC and nubUAS.ORF.GW.Tag:HA, under the control of Scer\GAL4da.G32 triggers the striking generation of ectopic neuroblasts throughout the ectoderm of stage 12 embryos, with extensive ectopic proliferation, as compared to controls.
