ykiS168A.UAS.Tag:V5 expression driven by Scer\GAL4insc-Mz1407 does not result in obvious signs of quiescence in the larval brain, as neuroblasts show the expected rounded morphology and do not show changes in cell division (both DNA replication/EdU staining and Mitosis/phospho-H3), as compared to controls.

Expressing ykiS168A.UAS.Tag:V5 under the control of Scer\GAL4ptc-559.1 stimulates severe tissue overgrowth in the wing and eye discs and results in a significant expansion of the anterior-posterior compartment boundary of the wing disc in third instar larvae.

Third instar larvae expressing ykiS168A.UAS.Tag:V5 under the control of Scer\GAL4repo.PU, Scer\GAL446F or Scer\GAL4Gli.PU exhibit bulges along peripheral nerves, which contain increased nuclei numbers respectively from glial, perineurial glial and subperineurial glial cells, as compared to controls.

Expressing ykiS168A.UAS.Tag:V5 under the control of Scer\GAL4insc-Mz1407 results in a significant increase in volume in the central nervous system of third instar larvae.

Flies expressing ykiS168A.Scer\UAS.T:SV5\V5 under the control of Scer\GAL4tin.CΔ4 show cardiac hypertrophy: ventricular diameter at the end of systole and diastole is reduced compared with controls and the heart walls are thicker. The average ploidy of cardiomyocytes expressing ykiS168A.Scer\UAS.T:SV5\V5 is increased compared with controls.

Flies expressing ykiS168A.Scer\UAS.T:SV5\V5 under the control of Scer\GAL4tin.CΔ4 and where expression is limited to the wandering third instar larval stage onwards (using Scer\GAL80ts.αTub84B) show reduced ventricular diameter at the end of diastole (EDD), whereas the EDD from flies that begin expressing ykiS168A.Scer\UAS.T:SV5\V5 in adulthood do not differ from controls.

Expression of ykiS168A.Scer\UAS.T:SV5\V5 under the control of Scer\GAL4GMR.PU results in eye overgrowth.

Expression of ykiS168A.Scer\UAS.T:SV5\V5 under the control of Scer\GAL4c768 results in overgrowth of the neuroepithelium in the third larval instar optic lobe.

Expression of ykiS168A.Scer\UAS.T:SV5\V5 under the control of Scer\GAL4GMR.PF produces enlarged and irregular eyes.

Wing disc clones expressing ykiS168A.Scer\UAS.T:SV5\V5 under the control of Scer\GAL4Scer\FRT.Act5C induce mild growth enhancement.

Expressing ykiS168A.Scer\UAS.T:SV5\V5 under the control of Scer\GAL4repo.PU induces a substantial increase in glial cell number in third instar larval eye discs. The size of the ventral nerve cord and brain hemispheres is increased and the total number of glial cells is increased throughout the brain - the optic stalk is thicker and contains many more glial cells, and an increased number of glial cells is seen in the outer cortex of the brain hemispheres. Ethyl deoxyuridine (EdU) labelling shows that glial expression of ykiS168A.Scer\UAS.T:SV5\V5 results in increased retinal glial cell proliferation compared to controls. As in wild type, central brain glia expressing ykiS168A.Scer\UAS.T:SV5\V5 are rarely seen to proliferate.

Overexpression of ykiS168A.Scer\UAS.T:SV5\V5 driven by Scer\GAL4Act5C.PI in somatic clones induces tumorigenesis in the ovarian follicular epithelium.

Expression of ykiS168A.Scer\UAS.T:SV5\V5 under the control of Scer\GAL4GMR.PF results in an enlarged eye which is folded due to the extensive overgrowth.

Expression of ykiS168A.Scer\UAS.T:SV5\V5 under the control of Scer\GAL4sd-SG29.1 results in an extended third instar larval stage and eventual late larval lethality.

Flies carrying ykiS168A.Scer\UAS.T:SV5\V5 in the presence of two copies of Scer\GAL4GMR.PF and one copy of Scer\GAL80αTub84B.PL show only a subtle eye overgrowth.
