Título: | EGFR controls Drosophila tracheal tube elongation by intracellular trafficking regulation |
Autor: | Olivares-Castiñeira, Ivette CSIC; Llimargas, Marta CSIC ORCID | Fecha de publicación: | 5-jul-2017 | Editor: | Public Library of Science | Citación: | PLoS Genetics 13(7): e1006882 (2017) | Resumen: | Development is governed by a few conserved signalling pathways. Amongst them, the EGFR pathway is used reiteratively for organ and tissue formation, and when dysregulated can lead to cancer and metastasis. Given its relevance, identifying its downstream molecular machinery and understanding how it instructs cellular changes is crucial. Here we approach this issue in the respiratory system of Drosophila. We identify a new role for EGFR restricting the elongation of the tracheal Dorsal Trunk. We find that EGFR regulates the apical determinant Crb and the extracellular matrix regulator Serp, two factors previously known to control tube length. EGFR regulates the organisation of endosomes in which Crb and Serp proteins are loaded. Our results are consistent with a role of EGFR in regulating Retromer/WASH recycling routes. Furthermore, we provide new insights into Crb trafficking and recycling during organ formation. Our work connects cell signalling, trafficking mechanisms and morphogenesis and suggests that the regulation of cargo trafficking can be a general outcome of EGFR activation | Versión del editor: | https://doi.org/10.1371/journal.pgen.1006882 | URI: | http://hdl.handle.net/10261/174456 | DOI: | 10.1371/journal.pgen.1006882 | ISSN: | 1553-7390 | E-ISSN: | 1553-7404 |
