Expression of scribKK101128 under the control of Scer\GAL4Hml.Δ does not lead to a significant difference in survival as compared to controls when larvae are infected with the nematode Heterorhabditis bacteriophora and its associated bacterium Photorhabdus luminescens.

Expression of scribKK101128 under the control of Scer\GAL4ple.PF or Scer\GAL4GMR13F02 (in combination with a Dicer-2 transgene to enhance RNAi efficiency) results in enhanced memory after conditioning in an olfactory conditioning assay.

The expression of scribKK101128 under the control of Scer\GAL4sd-SG29.1 leads to dysplastic overgrowths only in the wing disc hinge region, as compared to controls.

The clonal expression of scribKK101128 under the control of Scer\GAL4Act5C.PI (together with Dicer-2, for efficient RNAi) within mosaic third instar larval wing discs leads to dysplastic overgrowths only in the hinge region and leads to apoptosis (Dcp1 staining) in some scribKK101128-expressing cells in both the wing pouch and hinge regions of the mosaic wing disc, particularly at the boundary with non-expressing cells, as compared to controls; these overgrowths are particularly prevalent at the dorsal hinge region and, within it, at medial fold.

The double expression of Ras85DV12.UAS and scribKK101128 for 3 days during larval development under the combined control of Scer\GAL4hh.PU and Gal80[ts] results in increased DNA damage (comet assay) and decreased DNA damage response (phospho-H2Av) in third instar larval wing discs.

Co-expression of scribKK101128 exacerbates the increased hemocyte count observed in larvae expressing Ras85DV12.Scer\UAS under the control of Scer\GAL4Hml.Δ; these larvae are viable up to pupal stage and prepare for pupation, but only a subset of these pupae successfully eclose at 25[o]C, as compared to controls. None of these flies eclose when reared at 29[o]C, and pupae exhibit dessication and an absence of precursors of adult structures, in contrast to controls.

Larvae expressing both Ras85DV12.Scer\UAS and scribKK101128 under the control of Scer\GAL4Hml.Δ exhibit no significant difference in wound healing; larvae wounded and infected with the bacteria Staphylococcus aureus, Erwinia carotovora, or E.coli survive equally well as controls; and hemocytes isolated from larvae exhibit normal phagocytosis levels upon exposure to to heat killed E. coli, as compared to controls.

Larvae expressing both Ras85DV12.Scer\UAS and scribKK101128 under the control of Scer\GAL4Bx-MS1096 infected with the nematode Heterorhabditis bacteriophora and its associated bacterium Photorhabdus luminescens, do not show a significant difference in survival as compared to controls; but when these constructs are driven under the control of Scer\GAL4Hml.Δ, infected larvae show a significant increase in mortality as compared to controls, and also show a similar decrease in motility upon nematode infection as seen in those expressing only Ras85DV12.Scer\UAS.

The co-expression of Ras85DV12.UAS and scribKK101128 under the control of Scer\GAL4ap-md544 induces wing disc neoplasia which, when transplanted, can form solid tumors in the host; in both wing discs and allografts, there is amplification of the resident myoblast population, as well as accumulation of circulating hemocytes. The same tumor induction and hemocyte recruitment occurs if expression is only induced in wing disc transplants (expression induction is controlled by Gal80[ts] and temperature-shift). Hemocyte ablation on the host (by expressing rprUAS.C under the control of Scer\GAL4He.PZ) does not suppress the tumor-like growth.

The wing disc hinge overgrowths induced by the clonal expression of scribKK101128 under the control of Scer\GAL4Act5C.PI (together with Dicer-2, for efficient RNAi) are enhanced by the co-expression of Stat92EΔNΔC.UASp.Tag:HA, leading to large tumor masses; this co-expression still does not lead to overgrowths in the wing pouch area and does not affect the basal delamination/extrusion observed upon scribKK101128 single expression.

The clonal co-expression of scribKK101128 and RhoGEF2HMS01118 under the control of Scer\GAL4Act5C.PI (together with Dicer-2, for efficient RNAi) in third instar larval wing discs leads to a significant proportion of apical delamination, which does not occur upon scribKK101128 single expression; the additional co-expression of Stat92EΔNΔC.UASp.Tag:HA leads to overgrowths in the wing pouch domain, which does not occur upon scribKK101128 single expression or scribKK101128, RhoGEF2HMS01118 double expression.
