[PDF][PDF] Dorsal-ventral gene expression in the Drosophila embryo reflects the dynamics and precision of the dorsal nuclear gradient
Patterning of the dorsal-ventral axis in the early Drosophila embryo depends on the nuclear
distribution of the Dorsal transcription factor. Using live two-photon light-sheet microscopy, …

[HTML][HTML] Dynamic Interpretation of Hedgehog Signaling in the Drosophila Wing Disc
M Nahmad, A Stathopoulos - PLoS biology, 2009 - journals.plos.org
Morphogens are classically defined as molecules that control patterning by acting at a
distance to regulate gene expression in a concentration-dependent manner. In the Drosophila …

Spatiotemporal mechanisms of morphogen gradient interpretation
M Nahmad, AD Lander - Current opinion in genetics & development, 2011 - Elsevier
Few mechanistic ideas from the pre-molecular era of biology have had as enduring an
impact as the morphogen concept. In the classical view, cells in developing embryos obtain …

A cis-regulatory sequence of the selector gene vestigial drives the evolution of wing scaling in Drosophila species
Scaling between specific organs and overall body size has long fascinated biologists, being
a primary mechanism by which organ shapes evolve. Yet, the genetic mechanisms that …

[HTML][HTML] A dynamic cell recruitment process drives growth of the Drosophila wing by overscaling the vestigial expression pattern
Organs mainly attain their size by cell growth and proliferation, but sometimes also grow
through recruitment of undifferentiated cells. Here we investigate the participation of cell …

[HTML][HTML] Vestigial-dependent induction contributes to robust patterning but is not essential for wing-fate recruitment in Drosophila
Cell recruitment is a process by which a differentiated cell induces neighboring cells to adopt
its same cell fate. In Drosophila, cells expressing the protein encoded by the wing selector …
