Slik-Induced Overgrowth in the Wing

(A) Cuticle preparation of a ptcGAL4 adult wing.
(B) Cuticle preparation of a ptcGAL4 UAS-slik adult wing.
(C) Overlay of (A) (green) and (B) (red) aligned in the anterior margin. Note the increased separation of veins 3 and 4 in the center of the wing (arrow).
(D) Cuticle preparation of a ptcGAL4 UAS-slik UAS-p35 adult wing. The separation of veins 3 and 4 was larger than in (C).
(E) Measurement of the area enclosed by veins 3 and 4 in ptcGAL4 and ptcGAL4 UAS-slik wings. Error bars indicate standard deviation (*: p < 0.001 using a Student's t-test).
