Detailed Description
Statement
Reference

Expression of tllUAS.cKa under the control of Scer\GAL4elav-C155 increases mitotic proliferation of neuroblasts and their daughter cells in the ventral nerve cord during late embryogenesis, compared to controls; expression under the control of Scer\GAL4vg.int2.1 results in the appearance of neuroblasts and their daughter cells in the larval wing disc, which are not seen in controls.

Ectopic expression of tllScer\UAS.cKa by Scer\GAL4elav.Switch.PO results in hyperplasia and supernumerary neuroblasts in the 3rd instar larval brain and the mid-pupal brain (40hr after puparium formation).

Expression of tllUAS.cKa, otpUAS.ORF.GW.Tag:HA, ermUAS.ORF.GW.Tag:HA and Doc2UAS.cRa under the control of Scer\GAL4elav-C155 significantly increases total cell number and the number of neuroblasts in the late embryonic ventral nerve cord, compared to controls; expression under the control of Scer\GAL4wg.PU results in a trend towards increased symmetric (abnormal) neuroblast division and significantly increased asymmetric (normal) daughter (ganglion mother cell) division as well as a significant increase in the number of cells in the NB5-6 lineage, compared to controls; expression under the control of Scer\GAL4pros.PMG significantly increases the number of neuroblasts and daughters in S-phase, with no effect on cell cycle speed, compared to controls; expression under the control of Scer\GAL4da.PU increases the number of mitotic cells, neuroblasts, daughters and neurons, and reduces the number of glia, with a thickening of the CNS, compared to controls.

Co-overexpression of prosScer\UAS.cMa and tllScer\UAS.cKa by Scer\GAL4elav.Switch.PO rescues the tllScer\UAS.cKa-induced brain hyperplasia in third instar larvae.
