2016 lab News
Claudia Vasquez publishes eLife paper | December 2016
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.
Jonathan Coravos publishes Developmental Cell paper | October 2016
Congratulations Jonathan on publishing his work "Apical Sarcomere-like Actomyosin Contracts Nonmuscle Drosophila Epithelial Cells" in Developmental Cell. Jonathan discovered that the apical actin cortex of an epithelial cell can be organized like a muscle sarcomere to promote contraction and tissue folding.

Congratulations Mimi Xie for publishing her work "Loss of Gα12/13 Exacerbates Apical Area-dependence of Actomyosin Contractility" in Molecular Biology of the Cell! Mimi showed how apical actin density can depend on apex size. Suppressing this dependence is important to coordinate contractility across a tissue.

2015 lab news
Jeanne publishes Developmental Cell paper | December 2015
Congratulations Jeanne, for publishing her work "Stable Force Balance between Epithelial Cells Arises from F-Actin Turnover" in Developmental Cell. Jeanne showed that stable force balance between cells in a tissue requires robust actin filament turnover. The paper was also highlighted by the journal. Read the paper and the highlight article.

Mimi Xie’s paper in Nature Communications | May, 2015
Congratulations to graduate student, Mimi Xie, for her publication "Intracellular signalling and intercellular coupling coordinate heterogeneous contractile events to facilitate tissue folding” in Nature Communications. In the paper, Mimi showed that cells exhibit three classes of contractile events, unconstricting, unratcheted, and ratcheted. Mimi demonstrated that cells undergo transitions between different classes of contractions, going from unconstricting or unratcheted contractions to ratcheted contractions. A transcription factor that regulates this developmental stage is important for the proper order of contractile events. It is important for cells to generate ratcheted contractions because this promotes cooperation between cells.
Elena Kingston accepted to MIT Biology PhD program | April, 2015
Congratulations Elena Kingston! Elena, our technical assistant, has decided to stay at MIT and complete her thesis. We are thrilled that you will still be around.

Congratulations to graduate student, Jonathan Coravos, on passing his qualifying exam.
Nature Cell Biology Paper | July, 2013
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.
