The expression of ykiUAS.cHa from the second instar larval stage under the combined control of Scer\GAL4ap-md544 and Gal80[ts] leads to the third instar larval wing disc dorsal compartment presenting a significant increase in size, but does not lead to polyploidy/aneuploidy or epithelial organization defects (i.e. cells show normal sub-cellular localization of Discs large protein), as compared to controls; these larvae eventually enter pupariation but die as pupae. Expression under the control of either Scer\GAL4hh.PU or Scer\GAL4e22c also leads to a larger third instar larval wing disc posterior compartment, as compared to controls.

Overexpression of ykiScer\UAS.cHa driven in the fat body of male flies by Scer\GAL4r4 (or driven by Scer\GAL4yolk in female fat bodies) significantly decreases survival of flies in response to Gram-positive bacteria (Staphylococcus aureus or Enterococcus faecalis) and a fungus (Aspergillus fumigatus), compared to controls; expression with Scer\GAL4r4 in males has no effect on survival in response to Gram-negative bacteria (Erwinia carotovora carotovora 15 or Escherichia coli). Bacterial load (measured as colony forming units 24hr post infection) of S. aureus (but not Erwinia carotovora carotovora 15) significantly increases in adult flies, compared to controls.

Third instar larvae expressing ykiScer\UAS.cHa under the control of Scer\GAL4RapGAP1-OK6 show normal number of satellite boutons on neuromuscular junctions relative to controls.

Expression of ykiScer\UAS.cHa under the control of Scer\GAL4C587 has no apparent germarium phenotype.

Expression of ykiScer\UAS.cHa under the control of Scer\GAL4en.PU in third instar larvae leads to increased area of the posterior compartment of the wing disc.

Expression of ykiScer\UAS.cHa under the control of Scer\GAL4GMR.PU leads to increased eye size.

Eye disc clones expressing ykiScer\UAS.cHa exhibit tissue overgrowth.

Expression of ykiScer\UAS.cHa under the control of Scer\GAL4GMR.PU results in a disorganised eye that is overgrown.

Overexpression of ykiScer\UAS.cHa under the control of Scer\GAL4GMR.PF results in overgrown adult eyes.

Overexpression of ykiScer\UAS.cHa under the control of Scer\GAL4GMR.PF results in ectopic proliferation in the GMR region posterior to the second mitotic wave, while little apoptosis is seen in the eye-antennal disc.

Expression of ykiScer\UAS.cHa 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 ykiScer\UAS.cHa in wild-type tissue results in a mild overgrowth phenotype.

Expression of ykiScer\UAS.cHa under the control of Scer\GAL4GMR.PF results in overgrowth of the eye.

Pupal eye clones of cells overexpressing ykiScer\UAS.cHa driven by Scer\GAL4αTub84B.PL exhibit increased clonal area as well as overproliferation of interommatidial cells.

Wing disc clones expressing ykiScer\UAS.cHa (under the control of Scer\GAL4tub.PU) are large in size. Adjacent wild-type clones are much reduced in size compared to control sibling clones.

Wing disc clones expressing ykiScer\UAS.cHa under the control of Scer\GAL4Act5C.PP are large in size compared to control clones.

Expression of ykiScer\UAS.cHa under the control of Scer\GAL4GMR.PF results in increased eye size compared to controls.

Mosaic clones expressing ykiScer\UAS.cHa under the control of Scer\GAL4αTub84B.PP are notably larger than their wild-type twins in wing discs dissected either at 60 hours or 48 hours after heat-shock induction. Furthermore ykiScer\UAS.cHa-wild-type twins almost disappear from the epithelium at 120 hours after egg laying. These differences in size are also prominent when discs are dissected at 96 hours after egg laying. The clonal expansion of ykiScer\UAS.cHa-expressing clones is correlated with non-autonomous apoptosis. The size advantage of ykiScer\UAS.cHa clones and the induction of apoptosis in wild-type cells indicates cell competition.

Adherens junctions of wing disc cells expressing ykiScer\UAS.cHa under the control of Scer\GAL4en-e16E are 1.78 times wider than those of wild-type control cells in the same disc.

Expression of ykiScer\UAS.cHa under the control of Scer\GAL4GMR.PF results in overgrown eyes.

Expression of ykiScer\UAS.cHa in the germline, under the control of Scer\GAL4nos.UTR.T:Hsim\VP16 or Scer\GAL4bam.T:Hsim\VP16, does not result in germline over-proliferation in testes or ovarioles.

Expression of ykiScer\UAS.cHa under the control of Scer\GAL4GMR.PF results in increased eye size compared to controls.

Expression of ykiScer\UAS.cHa under the control of Scer\GAL4tub.PU in clones in the eye disc results in enlarged and round-shaped clones.

Overexpression

of ykiScer\UAS.cHa in the developing eye, driven by Scer\GAL4GMR.PF, results in the generation of excess interommatidial pigment and bristle cells. Wild-type retinae have 1.67 cells in regions corresponding to one side of an

ommatidial hexagon between two vertices, while Scer\GAL4GMR.PF>ykiScer\UAS.cHa retinae have 5.9 cells in the same region.

Clones in the wing disc that express ykiScer\UAS.cHa under the control of Scer\GAL4tub grow much larger than wild-type controls. These clones cause the epithelium to bulge apically, due to a change in cell morphology in which nuclei move to a more apical position.

Expression of yki in the wing disc, under the control of Scer\GAL4hh-Gal4 results in an overgrowth of the posterior compartment.

Clones in the eye imaginal disc expressing ykiScer\UAS.cHa under the control of Scer\GAL4Act5C.PP fail to undergo cell-cycle arrest posterior to the second mitotic wave and continue the cell cycle. Cell death is significantly suppressed in the clones, even though abundant apoptosis is detected in neighbouring wild-type cells. Ommatidial clusters expressing ykiScer\UAS.cHa under the control of Scer\GAL4Act5C.PP have the normal complement of photoreceptor cells. The spacing between adjacent ommatidial clusters is increased due to the presence of extra interommatidial cells. The formation of extra interommatidial cells is most evident in pupal eye discs, where the clones contain many additional cells between photoreceptor clusters.

Clones expressing ykiScer\UAS.cHa under the control of Scer\GAL4Act5C.PP lead to marked overgrowth in adult epithelial structures. Wing imaginal discs containing multiple clones can reach up to eight times the area of control wing discs raised under identical conditions. Adult cuticles secreted by cells expressing ykiScer\UAS.cHa under the control of Scer\GAL4Act5C.PP display an unusual texture.

Wing imaginal disc cells expressing ykiScer\UAS.cHa under the control of Scer\GAL4Act5C.PP multiply faster than wild-type cells (a cell-doubling time of 12.0 hours compared to 16.1 hours in wild-type). These cells also minimize their contact with other cells and form round smooth cell borders. Cells expressing ykiScer\UAS.cHa under the control of Scer\GAL4Act5C.PP have a similar cell cycle profile and cell size distribution as compared to wild-type cells.

The co-expression of ykiUAS.cHa and pnutGD1512 from the second instar larval stage under the combined control of Scer\GAL4ap-md544 and Gal80[ts] enhances the third instar larval wing disc dorsal compartment enlargement induced by the expression of ykiUAS.cHa from the second instar larval stage under the combined control of Scer\GAL4ap-md544 and Gal80[ts], even leading to the formation of tumors and to cell polarity defects (i.e. mislocalization of Discs large protein); this tumor phenotype is enhanced by the co-expression of bskDN.UAS. The pnutGD1512, ykiUAS.cHa co-expressing larvae fail to pupate and, instead, continue to grow to form giant larvae.

The co-expression of ykiUAS.cHa and pnutGD1512 under the control of either Scer\GAL4hh.PU or Scer\GAL4e22c leads to a much more severe enlargement of the wing disc posterior compartment as compared to the ykiUAS.cHa single expression condition; the Scer\GAL4hh.PU-driven co-expression also leads to some of the expressing cells moving and invading the wing disc anterior compartment.

The third instar larval wing disc dorsal compartment enlargement induced by the expression of ykiUAS.cHa from the second instar larval stage under the combined control of Scer\GAL4ap-md544 and Gal80[ts] is significantly enhanced by the co-expression of diaHMS00308, chbHMS01146, pblJF02979 or IncenpGD7511.

The co-expression of ykiUAS.cHa enhances the polyploidy/aneuploidy in the third instar larval wing disc dorsal compartment induced by the expression of pnutGD1512 from the second instar larval stage under the combined control of Scer\GAL4ap-md544 and Gal80[ts].

Co-expression of cactHMS00084 suppresses the reduced survival rates in response to Staphylococcus aureus (and the increase in bacterial load) seen in male flies with overexpression of ykiScer\UAS.cHa driven in the fat body by Scer\GAL4r4.

The increased number of satellite boutons on neuromuscular junctions in third instar larvae expressing StripdsRNA.shRNA.Scer\UAS.9 under the control of Scer\GAL4RapGAP1-OK6 is not suppressed by co-expression of ykiScer\UAS.cHa.

The tumorous germaria phenotype induced by Scer\GAL4C587-driven expression of vgScer\UAS.cKa is partially rescued by co-expression of ykiScer\UAS.cHa.

The rather moderate tumorous germarium phenotype characteristic for adult female flies expressing cidsRNA.shRNA.Scer\UAS.P\T under the control of Scer\GAL4C587 is significantly improved by co-expression of ykiScer\UAS.cHa. Co-expression of ykiScer\UAS.cHa can also partially rescue the aggravated tumorous phenotype of flies expressing both cidsRNA.shRNA.Scer\UAS.P\T and hpoScer\UAS.cWa simultaneously.

Co-expression of taiHMS00673, nosJF02931, or piwiHMS00606 partially suppresses the wing disc posterior compartment overgrowth of larvae expressing ykiScer\UAS.cHa under the control of Scer\GAL4en.PU.

nosL7/Df(3R)Exel6183 partially suppresses the wing disc posterior compartment overgrowth of larvae expressing ykiScer\UAS.cHa under the control of Scer\GAL4en.PU.

Smurf15C dominantly enhances the enlarged eyes caused by overexpressing Scer\GAL4tub.PU>ykiScer\UAS.cHa.

Expression of Ncoa6HMS00664 suppresses the increase in eye size seen when ykiScer\UAS.cHa is expressed under the control of Scer\GAL4GMR.PU.

Expression of trrHMS01019 suppresses the increase in eye size seen when ykiScer\UAS.cHa is expressed under the control of Scer\GAL4GMR.PU.

Expression of ykiScer\UAS.cHa under the control of Scer\GAL4tub.PU in l(2)gl4 mutant wing disc mutant clones results in overproliferation and neoplastic transformation in both the proximal and distal domains, although the onset of neoplasia is delayed in distal cells compared to proximal cells.

Expression of ykiScer\UAS.cHa does not suppress the poor recovery rate of distal wing clones expressing vgScer\UAS.cKa under the control of Scer\GAL4tub.PU in a l(2)gl4 mutant background. Extensive cell death is still seen. Survival of proximal clones is somewhat improved, but unlike in l(2)gl4 mutant clones alone, neoplastic transformation is still not observed until day four of clone induction and the clones display dense cell packing and compact nuclear morphology.

Expression of hthHMS01112 does not suppress the overproliferation and neoplastic transformation seen in both the proximal and distal wing disc domains when ykiScer\UAS.cHa is expressed under the control of Scer\GAL4tub.PU in l(2)gl4 mutant clones.

TgiΔP has no effect on the tissue overgrowth seen in eye disc clones expressing ykiScer\UAS.cHa.

Co-expression of AckScer\UAS.cSb and ykiScer\UAS.cHa under the control of Scer\GAL4GMR.PU results in a massively overgrown eye.

Expression of ykiScer\UAS.cHa under the control of Scer\GAL4GMR.PU suppresses the reduced eye size caused by WGMR.PG and also results in a reduction in pigmentation.

Co-expression of Ncpro.Scer\UAS with ykiScer\UAS.cHa in the developing eye (under the control of Scer\GAL4GMR.PF), causes a significant reduction in the adult eye size, compared to expression of ykiScer\UAS.cHa alone.

Co-expression of Ncpro.Scer\UAS in ykiScer\UAS.cHa-expressing cells (both under the control of Scer\GAL4GMR.PF) results in a decrease in cell division and an increase in apoptosis, compared to expression of ykiScer\UAS.cHa alone.

Expression of ykiScer\UAS.cHa under the control of Scer\GAL4tub.PU within ft8 clones suppresses the retinal degeneration normally seen in them.

Overexpression of ykiScer\UAS.cHa in Ras85DV12.Scer\UAS MARCM clones generates larger tumorigenic overgrowths than in either single mutant clone.

Overexpression of ykiScer\UAS.cHa in dlg1GD4689 MARCM clones generates larger tumorigenic overgrowths than in either single mutant clone.

Co-expression of ykiScer\UAS.cHa with osScer\UAS.cZa in third instar eye imaginal disc MARCM clones results in a large tumorigenic overgrowth phenotype.

Animals co-expressing both kibraScer\UAS.cBa and ykiScer\UAS.cHa under the control of Scer\GAL4GMR.PF show the same eye overgrowth phenotype as animals expressing ykiScer\UAS.cHa alone under the control of Scer\GAL4GMR.PF.

Homozygous mutant clones of Df(1)djubI also overexpressing ykiScer\UAS.cHa driven by Scer\GAL4αTub84B.PL display phenotypes identical to overexpression of ykiScer\UAS.cHa alone.

Expression of ykiScer\UAS.cHa (using the MARCM system under the control of Scer\GAL4tub.PU) suppresses the growth defects seen in Df(1)btd-Sp1 leg disc clones generated in second instar larvae. ykiScer\UAS.cHa expression is also able to rescue the defects seen in Df(1)btd-Sp1 adult leg clones.

dm4 mutant wing discs expressing ykiScer\UAS.cHa under the control of Scer\GAL4tub.PU display very small double-mutant clones.

Expression of ykiScer\UAS.cHa and NcCARD.Scer\UAS under the control of Scer\GAL4T80 in dm4 mutant wing disc clones does not rescue clone size.

Co-expression of kibraScer\UAS.P\T.cYa and ykiScer\UAS.cHa under the control of Scer\GAL4GMR.PF results in an eye size similar to that caused by expression of ykiScer\UAS.cHa alone under the control of Scer\GAL4GMR.PF.

Mosaic clones expressing sdScer\UAS.cSa and ykiScer\UAS.cHa under the control of Scer\GAL4αTub84B.PP overgrow relative to ykiScer\UAS.cHa clones.

Mosaic clones expressing sdGD4744 and ykiScer\UAS.cHa under the control of Scer\GAL4αTub84B.PP, while larger than wild-type clones, do not exhibit the same level of hyperplasia as ykiScer\UAS.cHa clones.

Mosaic clones expressing dmGD1419 and ykiScer\UAS.cHa (both under the control of Scer\GAL4αTub84B.PP) display a significantly reduced number of cells compared to wild-type clones (and compared to dmGD1419 clones). The number of cells decreases even further when these clones are induced earlier in development.

In a competitive background (engineered through the presence of dmαTub84B.PBb that is removed in the mutant clones), ykiScer\UAS.cHa clones (under the control of Scer\GAL4αTub84B.PP) show a diminished ability to overgrow compared to a wild-type background. Besides the reduction in size, ykiScer\UAS.cHa clones show an important reduction in clone number both in discs and adult wings. Moreover ykiScer\UAS.cHa clones induced earlier in development are never recovered at the end of larval development.

In dmPL35/+;dmαTub84B.PBb females, ykiScer\UAS.cHa overexpression clones are smaller than wild-type, whereas in males they are completely outcompeted by 48 hours after heat-shock.

Mosaic clones expressing hthGD4741 and ykiScer\UAS.cHa (under the control of Scer\GAL4αTub84B.PP) exhibit down-regulation of dm in the notum and do not grow tumors in that region. These clones are indistinguishable from ykiScer\UAS.cHa clones in the wing pouch region (where hth expression is not detected).

Co-expression of sdScer\UAS.cSa and ykiScer\UAS.cHa under the control of Scer\GAL4GMR.PF results in eyes which are severely overgrown (and much larger than the eyes of animals expressing ykiScer\UAS.cHa alone under the control of Scer\GAL4GMR.PF) and folded. There is a general loss of eye pigmentation in the posterior region of the eye.

The large eye phenotype caused by expression of ykiScer\UAS.cHa under the control of Scer\GAL4GMR.PF is suppressed by sd12/+.

The large size and round shape of clones in the eye disc expressing ykiScer\UAS.cHa under the control of Scer\GAL4tub.PU is suppressed if the clones are also homozygous for sd12.

Homozygous vg83b27-R clones that are also expressing ykiScer\UAS.cHa under the control of Scer\GAL4tub.PU are readily recovered in the wing blade region of the wing disc.

In clones with a Df(3L)banΔ1 background, the induction of extra interommatidial cells causes by expression of ykiScer\UAS.cHa, under the control of Scer\GAL4GMR.PF in a wild-type background, is partially suppressed. The Scer\GAL4GMR.PF>ykiScer\UAS.cHa, Df(3L)banΔ1 retinae have 3.1 cells in regions corresponding to one side of an ommatidial hexagon between two vertices while the number if 5.9 cells in Scer\GAL4GMR.PF>ykiScer\UAS.cHa retinae but 1.67 cells in wild-type retinae.

Df(3L)banΔ1 mutant clones in the wing that overexpress ykiScer\UAS.cHa under the control of Scer\GAL4tub do not grow to be as large as those that overexpress ykiScer\UAS.cHa in wild-type clones.

There is a general loss of eye pigmentation in the posterior region of the eye.
