Congratulations Natalie on publishing her work “Actomyosin-based Tissue Folding Requires a Multicellular Myosin Gradient” in Development. Natalie discovered that a tissue-wide gradient in transcription and resulting contractility is necessary to fold a tissue. We had fun collaborating with Pearson Miller and the Dunkel Lab on this project.

Jonathan Coravos gave an amazing seminar and successfully defended his thesis. Well done Jonathan! Have fun in Chile!

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.

The Martin lab won the coveted group costume competition for the Biology department Halloween party. They had a winning combination of fish-like pillows and various forms of wasabi.

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 Frank on publishing his work “LRhoA GTPase Inhibition Organizes Contraction During Epithelial Morphogenesis” in The Journal of Cell Biology! Frank showed how inhibiting RhoA can promote contraction during tissue folding. And read the Spotlight article on our paper, written by Alpha Yap. Also, congratulations on your new position as a Research Assistant Professor at Vanderbilt University!

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.

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 to Dr. Hannah Yevick for being awarded a prestigious NIH fellowship.

Biology student Marlis Denk-Lobnig joins the lab. Marlis did her undergraduate work at Georg-August University in Göttingen, Germany. Marlis is interested in applying computational approaches to studying signaling networks in an embryo.

Adam Martin has been promoted to Associate Professor, effective July 1, 2016.

Congratulations Jeanne Jodin, 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.
