APM_GUI: analyzing particle movement on the cell membrane and determining confinement KU Leuven
ABSTRACT:
Compensatory Cell Movements Confer Robustness to Mechanical Deformatio during Embryonic Developmentn KU Leuven
Embryonic development must proceed despite both internal molecular fluctuations and external perturbations. However, mechanisms that provide robustness to mechanical perturbation remain largely uncharacterized. Here, we use light-sheet microscopy, comprehensive single-cell tracking, and targeted cell ablation to study the response of Caenorhabditis elegans embryos to external compression. Compression changes the relative positions of many cells ...
Syntenin, a syndecan adaptor and an Arf6 phosphatidylinositol 4,5-bisphosphate effector, is essential for epiboly and gastrulation cell movements in zebrafish KU Leuven
Epiboly, the spreading and the thinning of the blastoderm to cover the yolk cell and close the blastopore in fish embryos, is central to the process of gastrulation. Despite its fundamental importance, little is known about the molecular mechanisms that control this coordinated cell movement. By a combination of knockdown studies and rescue experiments in zebrafish (Danio rerio), we show that epiboly relies on the molecular networking of ...
ROPGAP-dependent interaction between brassinosteroid and ROP2-GTPase signaling controls pavement cell shape in Arabidopsis Ghent University Flanders Institute for Biotechnology
The epidermal pavement cell shape in Arabidopsis is driven by chemical and mechanical cues that direct partitioning mechanisms required for the establishment of the lobe- and indentation-defining polar sites. Brassinosteroid (BR) hormones regulate pavement cell morphogenesis, but the underlying mechanism remains unclear. Here, we identified two PLECKSTRIN HOMOLOGY GTPase-ACTIVATING proteins (PHGAPs) as substrates of the GSK3-like kinase ...
