Expression of InRGD104 under the control of Scer\GAL4Orco.PU or Scer\GAL4Or47a.PU does not alter the starvation-dependent increase in attraction to pentyl acetate or the levels of food intake as compared to control larvae. It leads to a significant increase in body weight under the control of Scer\GAL4Orco.PU when compared to control larvae.

The adulthood-only expression of InRGD104 under the combined control of Scer\GAL4C587 and Gal80[ts] leads to several germarium defects compared to controls, including: smaller germaria with fewer cysts and budding fewer egg chambers; a significant and progressive decrease in the number of escort cells, which fail to completely wrap germ cell cysts; germline stem cells dividing less frequently and progressively decreasing in number; and germ cell cysts showing a lower proportion of cell division; but no defect in the number of cap cells.

The adulthood-only expression of InRGD104 leads to a significant and progressive decrease in the number of germline stem cells in the adult germarium when under the control of Scer\GAL4ptc-559.1, while leading to a significant decrease in the number of escort cells in the adult germarium when under the control of Scer\GAL4bab1-Gal4, as compared to controls; the Scer\GAL4bab1-Gal4-driven expression also leads to a significant decrease in the number of cap cells in the adult germarium, as compared to controls.

Escort cell (within clones) expressing InRGD104 under the control of Scer\GAL4Act5C.PU show blunted extension of membrane processes that fail to completely wrap germ cell cysts, as compared to controls.

Presynaptic expression of InRGD104 under the control of Scer\GAL4elav-C155 causes synaptic retractions in less than 10% of synapses.

Expression of InRGD104 in the posterior wing compartment under the control of Scer\GAL4en-e16E does not affect wing vein formation.

Adults expressing InRGD104 under the control of Scer\GAL4elav.PLu (in the presence of Dcr-2Scer\UAS.cDa to increase the efficiency of RNAi) do not show a significant defect in avoidance of noxious temperature (46[o]C) compared to control flies.

Depending on the insertion line used, expression under the control of Scer\GAL4Mef2.PR can result in a weak flyer phenotype or early pupal lethality.

Expression under the control of Scer\GAL4pnr-MD237 may result in semi-lethality, depending on the insertion line used.

Expression under the control of Scer\GAL4pnr-MD237 results in bristle morphology defects on the notum in 100% or 80-90% of the Scer\GAL4pnr-MD237 expression domain, depending on the insertion line used.

Expression of InRGD104 under the control of Scer\GAL4Act during the pupal stages (Scer\GAL80ts.αTub84B present in the animals has been inactivated by shifting to the restrictive temperature following the larval/pupal transition) results in smaller and lighter adults than normal, with reduced appendages.

Reference

SIIN/+;InR05545/+ flies do not exhibit an enhanced photoreceptor differentiation phenotype compared to SIIN heterozygotes.

Depletion of InR, through expression of InRGD104, slightly reduces tumour size in Ras85DV12.Scer\UAS-dlg1GD4689 MARCM clones.
