Congratulations Dr. Jackson on defending your PhD and getting a postdoc position in Germany. Best of luck.
Congratulations Fernando on a productive summer and successfully presenting your poster at the end of summer program. We look forward to seeing what you do in the future!
Congratulations to postdoc, Frank Mason, for the recent publication of his paper, “Apical domain polarization promotes actin-myosin assembly to drive ratchet-like apical constriction” on Nature Cell Biology. In the paper, Mason et al. show that the signals that regulate contractile forces in constricting cells exhibit a spatial organization within the apical domain of the cell. Signals that activate myosin motors are polarized to the center of the apical domain. Actin polymerization in this domain suppresses junctional protein localization, restricting junctional proteins to cell-cell interfaces. Thus, a “radial” cell polarity is established, which is shown to be important for apical constriction.
Congratulations Elena Kingston on winning the best poster prize at the Building 68 retreat. We have won a poster prize each year for the past 3 years. Nice job Mimi, Claudia, and now Elena.
Congratulations Claudia on publishing her work “Drosophila Non-muscle Myosin II Motor Activity Determines the Rate of Tissue Folding” in eLife. Claudia demonstrated that myosin 2 motor activity sets the rate of apical constriction and tissue folding, showing that myosin 2 is the motor that drives these processes. This work was the result of a great collaboration with James Sellers’ lab at the National Institutes of Health.
Congratulations Jeanne Jodoin for publishing her work “Abl Suppresses Cell Extrusion and Intercalation During Epithelium Folding” in Molecular Biology of the Cell! Jeanne showed how the Abelson tyrosine kinase suppresses an EMT-like cell extrusion during tissue folding.
