biosights: August 5, 2013 - Epithelia restored by healing waves

submitted by: JCB
Epithelial cells around the edge of a wound assemble an actomyosin cable that constricts to draw the wound closed, but the events that precede cable formation are largely unknown. Antunes et al. reveal that wounding induces a wave of actomyosin assembly and cell constriction that flows toward the wound edge to promote cable assembly and tissue repair. This biosights episode presents the paper by Antunes et al. from the July 22, 2013, issue of The Journal of Cell Biology and includes an...

biosights: July 8, 2013 - Vinculin delivers a clutch performance

submitted by: JCB
At the leading edge of migrating cells, actin assembly and membrane protrusion are closely coupled with the formation of integrin-based focal adhesions that attach to the extracellular matrix. Thievessen et al. reveal that the focal adhesion protein vinculin acts as part of a molecular clutch that engages actin flow to coordinate actin and focal adhesion dynamics. This biosights episode presents the paper by Thievessen et al. from the July 8, 2013, issue of The Journal of Cell Biology and...
