Expression of ykiS111A.S168A.S250A.Scer\UAS.T:SV5\V5 in adult intestinal stem cells results in increased cell proliferation, leading to systemic organ wasting that affects the ovary, fat body and muscle.
Third instar larvae expressing ykiS111A.S168A.S250A.Scer\UAS.T:SV5\V5 under the control of Scer\GAL4RapGAP1-OK6 show normal number of satellite boutons on neuromuscular junctions relative to controls.
Expression of ykiS111A.S168A.S250A.Scer\UAS.T:SV5\V5 in adult midgut intestinal stem cells (under the control of Scer\GAL4esg-NP5130 and limited to the adult stage using Scer\GAL80ts.αTub84B) results in massive cell proliferation resulting in a bloating phenotype. This progressive phenotype is seen from 5 days after ykiS111A.S168A.S250A.Scer\UAS.T:SV5\V5 induction onwards. The ovaries of these flies degenerate progressively, and in contrast to the continuous mass seen in wild type flies the fat bodies of flies expressing ykiS111A.S168A.S250A.Scer\UAS.T:SV5\V5 appear as discontinuous patches that later degenerate completely. Progressive climbing defects and downturned wings are also seen. The mitochondria of muscles expressing ykiS111A.S168A.S250A.Scer\UAS.T:SV5\V5 are swollen and often associated with empty space. Mitochondrial degeneration is seen.
The volume of extractable hemolymph from flies expressing ykiS111A.S168A.S250A.Scer\UAS.T:SV5\V5 in adult midgut intestinal stem cells (under the control of Scer\GAL4esg-NP5130 and limited to the adult stage using Scer\GAL80ts.αTub84B) is greatly increased compared to controls. The concentration of trehalose in the hemolymph is significantly increased. Whole-body trehalose levels are increased. Whole-body triglycerides and glycogen are reduced compared to controls. Food intake and excretion are unaffected.
Increased glucose incorporation is seen in the midgut of flies expressing ykiS111A.S168A.S250A.Scer\UAS.T:SV5\V5 in adult midgut intestinal stem cells (under the control of Scer\GAL4esg-NP5130 and limited to the adult stage using Scer\GAL80ts.αTub84B) compared with controls. In other parts of these flies, glucose incorporation is reduced.

Expression of ykiS111A.S168A.S250A.Scer\UAS.T:SV5\V5 under the control of Scer\GAL4GMR.PF during the adult stage (using the a temperature-sensitive Scer\GAL80 line to control the timing of expression) results in unequivocal, albeit weak, progressive degeneration of photoreceptor cells.
Expression of ykiS111A.S168A.S250A.Scer\UAS.T:SV5\V5 under the control of Scer\GAL4GMR.PF results in greatly reduced viability, with the eyes being enlarged and highly folded in surviving adults.
