Expression of RxScer\UAS.cKa under the control of Scer\GAL4insc-Mz1407 or Scer\GAL4elav-C155 results in an increase in the diameter of third instar mushroom body neuroblasts (NBs) and GMCs, but no significant increase in the mitotic index of mushroom body NBs, basolateral dorsal NBs or basolateral posterior NBs; expression of RxScer\UAS.cKa under the control of Scer\GAL4insc-Mz1407 results in an increase in the diameter of basolateral dorsal NBs and GMCs, and basolateral posterior NBs and GMCs, as compared to wild type.
Expression of RxScer\UAS.cKa under the control of Scer\GAL4wor.PU or Scer\GAL4insc-Mz1407 does not affect the longevity of mushroom body NBs, as compared to controls.
