[PDF][PDF] Dorsal-ventral gene expression in the Drosophila embryo reflects the dynamics and precision of the dorsal nuclear gradient

GT Reeves, N Trisnadi, TV Truong, M Nahmad, S Katz… - Developmental cell, 2012 - cell.com
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

…, TA Evans, M Nahmad - Journal of …, 2023 - journals.biologists.com
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 …

The dynamics of developmental system drift in the gene network underlying wing polyphenism in ants: a mathematical model

M Nahmad, L Glass, E Abouheif - Evolution & development, 2008 - Wiley Online Library
Understanding the complex interaction between genotype and phenotype is a major challenge
of Evolutionary Developmental Biology. One important facet of this complex interaction …

[HTML][HTML] Size-dependent regulation of dorsal–ventral patterning in the early Drosophila embryo

M Garcia, M Nahmad, GT Reeves, A Stathopoulos - Developmental biology, 2013 - Elsevier
How natural variation in embryo size affects patterning of the Drosophila embryo dorsal–ventral
(DV) axis is not known. Here we examined quantitatively the relationship between …

[HTML][HTML] Expanding signaling-molecule wavefront model of cell polarization in the Drosophila wing primordium

JC Wortman, M Nahmad, PC Zhang… - PLoS Computational …, 2017 - journals.plos.org
In developing tissues, cell polarization and proliferation are regulated by morphogens and
signaling pathways. Cells throughout the Drosophila wing primordium typically show …

[HTML][HTML] MAPPER: An Open-Source, High-Dimensional Image Analysis Pipeline Unmasks Differential Regulation of Drosophila Wing Features

N Kumar, FJ Huizar, PA Brodskiy, M Nahmad… - Frontiers in …, 2022 - frontiersin.org
Phenomics requires quantification of large volumes of image data, necessitating high
throughput image processing approaches. Existing image processing pipelines for Drosophila …

[HTML][HTML] A dynamic cell recruitment process drives growth of the Drosophila wing by overscaling the vestigial expression pattern

…, HA Alvarez, M Flores-Flores, O Chara, M Nahmad - Developmental …, 2020 - Elsevier
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

…, R Rodríguez-Muñoz, J Zartman, M Nahmad - Biology …, 2023 - journals.biologists.com
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 …
