UAS regulatory sequences drive expression of a short inverted repeat.
Expression of Lgr3GL01056 (together with UAS-Dicer2 to enhance RNAi efficiency) under the control of either Scer\GAL4αTub84B.PL or Scer\GAL4elav.PU (but not Scer\GAL4repo or Scer\GAL4Ptth.cMa) abrogates the growth inhibition of undamaged (anterior) tissues - eye discs - in third instar larvae (104 hr after egg laying, AEL) following targeted irradiation (limited to posterior tissues and administered in late second instar, at 80 hr AEL) which is observed in wild-type larvae and also strongly reduces the developmental delay the regenerative growth of damaged tissues normally produces. Lgr3GL01056 expression driven by Scer\GAL4GMR18A01 or Scer\GAL4phm.PO combined with Scer\GAL80elav.PY or Scer\GAL4nSyb.PS also prevents the growth inhibition of undamaged tissue in targeted irradiation larvae, however Scer\GAL4phm.PO-controlled expression does not decrease the irradiation damage-induced pupariation delay compared to controls.
In the absence of expression of tissue damage, expression of Lgr3GL01056 controlled by either Scer\GAL4αTub84B.PL or Scer\GAL4phm.PO does not inhibit eye disc tissue growth, with the Scer\GAL4αTub84B.PL driver as the discs are actually larger relative to age-matched controls.
Expression of Lgr3GL01056 under the control of either Scer\GAL4nSyb.PU, Scer\GAL4Lgr3.T:Hsim\VP16 or Scer\GAL4GMR19B09 results in a significant increase in fluctuating asymmetry of left and right wing areas compared to controls.
