Welcome Anthony McDouglal!

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.

Congratulations graduate student Claudia Vasquez on her publication “Dynamic myosin phosphorylation regulates contractile pulses and tissue integrity during epithelial morphogenesis” in The Journal of Cell Biology. Claudia’s paper was also highlighted in a video interview with the JCB news editor.

Congratulations to graduate student, Marlis Denk-Lobnig, who was featured in the MIT Biology department news. Read the article.

Jeanne comes to us from Vanderbilt University where she received a Ph.D. for her work on the mechanisms of dynein motor localization.

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.

Hannah received her Ph.D. from the Institut Curie in Paris, France. Her Bachelor’s degree is in Physics and she published a really cool paper on cells walking a “tightrope.” She is interested in collective cell behavior changing tissue shape.
