Animal expressing Wnt2Scer\UAS.cSa when driven by Scer\GAL4αTub84B.PC do not emerge from the puparium. these pharate adults do not exhibit any polarity defects. Wnt2Scer\UAS.cSa when driven by Scer\GAL4ptc-559.1 is lethal.
Expression of Wnt2Scer\UAS.cSa under the control of Scer\GAL4btl.PS results in hypertrophy of the dorsal trunk in the tracheal system. Expression of Wnt2Scer\UAS.cSa under the control of Scer\GAL4ptc-559.1 does not result in a naked cuticle phenotype.
Clones of cells in the anterior compartment of the dorsal epidermis of the adult abdomen (in the tergite) that are expressing Wnt2Scer\UAS.cSa under the control of Scer\GAL4αTub84B.PL in a dsunspecified background do not change the cell polarity of cells surrounding the clone.
Expression of Wnt2Scer\UAS.cSa under the control of Scer\GAL4wg.PM in a wgl-17 Wnt2unspecified double mutant background rescues some dorsal trunk in the trachea. However when Wnt2Scer\UAS.cSa is expressed under the control of Scer\GAL4btl.PS there is strong rescue, and more dorsal trunk is made.
