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.
Expression of Doc2Scer\UAS.cRa, driven by Scer\GAL4tin.cBa, results in efficient rescue of cardioblast specification in a Df(3L)DocA mutant background. When Doc2Scer\UAS.cRa is coexpressed with either tinScer\UAS.cYa or pnrScer\UAS.cHa, or both transgenes together, large numbers of extra cardioblasts are formed. Expression of all three transgenes results in double the amount of cardioblasts compared to wild type. Coexpression of Doc2Scer\UAS.cRa, tinScer\UAS.cYa, and pnrScer\UAS.cHa, under the control of Scer\GAL4twi.2PE, causes widespread ectopic cardioblast formation to a much greater extent than expression of Doc2Scer\UAS.cRa alone or in combination with tinScer\UAS.cYa plus pnrScer\UAS.cHa.
