Expression of RN17.Scer\UAS.T:Hsap\MYC under the simultaneous control of both Scer\GAL4slbo.2.6 and Scer\GAL4upd in the border cells blocks their migration in stage 10 egg chambers.

Embryos that express RN17.Scer\UAS.T:Hsap\MYC in the macrophages, under the control of Scer\GAL4srp, show a severe disruption in macrophage migration. Few macrophages reach the posterior region of the embryo, and a major gap remains in their distribution around the ventral nerve cord. Additionally, the macrophages were smaller and had smaller extensions than wild-type macrophages.

No animals expressing RN17.Scer\UAS.T:Hsap\MYC under the control of Scer\GAL4ptc-559.1 hatch. 93% of embryos expressing RN17.Scer\UAS.T:Hsap\MYC under the control of Scer\GAL4ptc-559.1 have a large dorsal hole in the cuticle (covering at least half of the dorsal aspect) and the remaining 7% have a partially open cuticle. Embryos expressing RN17.Scer\UAS.T:Hsap\MYC under the control of Scer\GAL4pnr-MD237 show a strong but variable dorsal closure defect. In embryos expressing RN17.Scer\UAS.T:Hsap\MYC under the control of Scer\GAL4pnr-MD237 or Scer\GAL4ptc-559.1, the leading edge cytoskeleton is assembled largely as in wild-type embryos and an initial stretching of the lateral ectodermal cells takes place during the dorsal closure stage. However, at later stages of dorsal closure, the mutant embryos show a detachment of the lateral ectoderm from the amnioserosa; the ectoderm retracts, with the cells resuming a non-elongated shape and the amnioserosa shrivels.

Coexpression of Gef26EP388 and RN17.Scer\UAS.T:Hsap\MYC in macrophages, under the control of Scer\GAL4srp, results in a substantial suppression of the RN17.Scer\UAS.T:Hsap\MYC macrophage phenotype. These embryos show only a minimal gap in the distribution of the macrophages around the ventral nerve cord at stage 14, and the macrophages form larger protrusions than in cells expressing only RN17.Scer\UAS.T:Hsap\MYC.

The dorsal closure defects seen in embryos expressing RN17.Scer\UAS.T:Hsap\MYC under the control of Scer\GAL4ptc-559.1 are substantially rescued by co-expression of cnoScer\UAS.cBa. The dorsal closure defects seen in embryos expressing RN17.Scer\UAS.T:Hsap\MYC under the control of Scer\GAL4ptc-559.1 are not rescued by co-expression of cnoΔN.Scer\UAS. Co-expression of bskScer\UAS.cBa does not rescue the dorsal closure defects seen in embryos expressing RN17.Scer\UAS.T:Hsap\MYC under the control of Scer\GAL4ptc-559.1.

Comments

The dorsal closure defects seen in embryos expressing RN17.Scer\UAS.T:Hsap\MYC under the control of Scer\GAL4ptc-559.1 are completely rescued by co-expression of RScer\UAS.T:Hsap\MYC and all the rescued animals hatch.
