- Loss of cell adhesion and enhancement of cell motility contribute to epithelial-to-mesenchymal transition during
development. These processes are related to a) rearrangement of cell-cell and cell-substrate adhesion molecules; b) cross
talk between extra-cellular matrix and internal cytoskeleton through focal adhesion molecules. Focal adhesions are
stringently regulated transient structures implicated in cell adhesion, spreading and motility during tissue development.
Importantly, despite the extensive elucidation of the molecular composition of focal adhesions, the complex regulation of
their dynamics is largely unclear. Here, we demonstrate, using live-imaging in medaka, that the microRNA miR-204
promotes both mesenchymal neural crest and lens cell migration and elongation. Overexpression of miR-204 results in
upregulated cell motility, while morpholino-mediated ablation of miR-204 activity causes abnormal lens morphogenesis and
neural crest cell mislocalization. Using a variety of in vivo and in vitro approaches, we demonstrate that these actions are
mediated by the direct targeting of the Ankrd13A gene, which in turn controls focal cell adhesion formation and
distribution. Significantly, in vivo restoration of abnormally elevated levels of Ankrd13A resulting from miR-204 inactivation
rescued the aberrant lens phenotype in medaka fish. These data uncover, for the first time in vivo, the role of a microRNA in
developmental control of mesenchymal cell migration and highlight miR-204 as a ''master regulator'' of the molecular
networks that regulate lens morphogenesis in vertebrates. (literal)

- Abstract
- Loss of cell adhesion and enhancement of cell motility contribute to epithelial-to-mesenchymal transition during development. These processes are related to a) rearrangement of cell-cell and cell-substrate adhesion molecules; b) cross talk between extra-cellular matrix and internal cytoskeleton through focal adhesion molecules. Focal adhesions are stringently regulated transient structures implicated in cell adhesion, spreading and motility during tissue development. Importantly, despite the extensive elucidation of the molecular composition of focal adhesions, the complex regulation of their dynamics is largely unclear. Here, we demonstrate, using live-imaging in medaka, that the microRNA miR-204 promotes both mesenchymal neural crest and lens cell migration and elongation. Overexpression of miR-204 results in upregulated cell motility, while morpholino-mediated ablation of miR-204 activity causes abnormal lens morphogenesis and neural crest cell mislocalization. Using a variety of in vivo and in vitro approaches, we demonstrate that these actions are mediated by the direct targeting of the Ankrd13A gene, which in turn controls focal cell adhesion formation and distribution. Significantly, in vivo restoration of abnormally elevated levels of Ankrd13A resulting from miR-204 inactivation rescued the aberrant lens phenotype in medaka fish. These data uncover, for the first time in vivo, the role of a microRNA in developmental control of mesenchymal cell migration and highlight miR-204 as a \"master regulator\" of the molecular networks that regulate lens morphogenesis in vertebrates.
