Apparent role of Tribolium orthodenticle in anteroposterior blastoderm patterning largely reflects novel functions in dorsoventral axis formation and cell survival
... Drosophila AP axis formation depends on spatial gradients of the maternal transcription factors Bicoid (Bcd) and Hunchback (Hb) (St Johnston and Nusslein-Volhard, 1992). Bcd activates multiple target genes, ...

Mirror represses pipe expression in follicle cells to initiate dorsoventral axis formation in Drosophila
... Mirr had previously been implicated in the specification of dorsal cell fates during eggshell patterning (Atkey et al., 2006), but it was assumed to be dispensable for establishing embryonic polarity (Peri et al., 2002; ...

Recombinase mediated cassette exchange reveals the selective use of Gq/G11 dependent and independent endothelin 1/endothelin type A receptor signaling in pharyngeal arch development
... The endothelin (Edn) system comprises three ligands (Edn1, Edn2 and Edn3) and their G-protein-coupled type A (Ednra) and type B (Ednrb) receptors. During embryogenesis, the Edn1/Ednra signaling is thought to regulate the ...
