A photoactivatable small-molecule inhibitor for light-controlled spatiotemporal regulation of Rho kinase in live embryos

Development, 139(2), 437–442.

By: A. Morckel n, H. Lusic n, L. Farzana n, J. Yoder n , A. Deiters n & N. Nascone-Yoder n 

author keywords: Small-molecule inhibitor; Rho kinase; Photocaging; Xenopus
MeSH headings : Animals; Body Patterning / drug effects; Dioxoles / metabolism; Dioxoles / pharmacology; Embryo, Nonmammalian / metabolism; Immunohistochemistry; Indoles / metabolism; Indoles / pharmacology; Mice; NIH 3T3 Cells; Pyridines / metabolism; Pyridines / pharmacology; Ultraviolet Rays; Xenopus laevis / embryology; Xenopus laevis / metabolism; rho-Associated Kinases / antagonists & inhibitors; rho-Associated Kinases / metabolism
TL;DR: A novel pharmacological agent that can be light activated to achieve spatiotemporally limited inhibition of Rho kinase activity in vivo is developed and application to the spatially heterogeneous problem of embryonic left-right asymmetry revealed a differential requirement for Rho signaling on the left and right sides of the primitive gut tube.

By: R. Reed n, M. Womble n, M. Dush n, R. Tull n, S. Bloom n, A. Morckel n, E. Devlin*, N. Nascone-Yoder n 

author keywords: gut; Xenopus; morphogenesis; endoderm, intercalation; elongation
MeSH headings : Animals; Animals, Genetically Modified; Body Patterning / genetics; Cell Polarity / genetics; Cell Shape / genetics; Embryo, Nonmammalian; Endoderm / cytology; Endoderm / embryology; Endoderm / metabolism; Gastrointestinal Diseases / congenital; Gastrointestinal Diseases / embryology; Gastrointestinal Tract / abnormalities; Gastrointestinal Tract / embryology; Gastrula / embryology; Gastrula / metabolism; Models, Biological; Morphogenesis / genetics; Nonmuscle Myosin Type IIB / genetics; Nonmuscle Myosin Type IIB / metabolism; Nonmuscle Myosin Type IIB / physiology; Signal Transduction / genetics; Xenopus / embryology; Xenopus / genetics; Xenopus / metabolism; rho-Associated Kinases / genetics; rho-Associated Kinases / metabolism; rho-Associated Kinases / physiology; rhoA GTP-Binding Protein / genetics; rhoA GTP-Binding Protein / metabolism; rhoA GTP-Binding Protein / physiology
TL;DR: The results suggest that the cellular and molecular events driving tissue elongation in the PGT are mechanistically analogous to those that function during gastrulation, but occur within a novel cylindrical geometry to generate an epithelial‐lined tube. (via Semantic Scholar)
