A dynacortin-deficient cell undergoing chemotaxis

Without cortical actin crosslinker dynacortin, cells fail to polarize properly during chemotaxis.  See Kabacoff et al. BMC Biol. 2007 for more information.

Actin Waves

Actin waves travel across the surface of a Dictyostelium cell.  This work was described in Zhou et al. Curr. Biol. 2010.

Actomyosin Network in Mechanosensation and Cytokinesis

Prepared by Johns Hopkins Art as Applied to Medicine masters student Mariya Khan, the video seeks to depict in understandable terms the major design considerations of the mechanosensitive contractile machinery of the dividing cell.

Careers in Science and Medicine

In this video, we describe the Johns Hopkins Initiative for Careers in Science and Medicine (CSM), which develops students (‘scholars’) from disadvantaged backgrounds into successful professionals, especially in the STEM and healthcare fields.

Cytokinesis

The movie depicts a stereotypical wild type dividing Dictyostelium cell.  The cell is engineered to express GFP-myosin II (green) and RFP-tubulin (red), which markes the mitotic spindle.

Cytokinesis Feedback

Dividing cells are exquisitely sensitive to mechanical stress (Effler et al. Curr. Biol. 2006, Ren et al. Curr. Biol. 2009, and Kee et al. Mol. Biol. Cell 2012).

Simulation of filamin mechanosensitive accumulation

Based on the molecular mechanisms of filamin, cellular concentrations, and force transmission, we are able to explain filamin mechanosensitive accumulation.  Please see Luo et al. Nat. Mater. 2013 for more information.

LuoetalMovie S6 Myosin II

Simulation of myosin II mechanosensitive accumulation

Drawing upon cellular concentrations, applied forces, and the myosin II bipolar thick filament assembly, we can explain myosin II mechanosensitive accumulation.  Please see Luo et al. Biophys. J. 2012 and Luo et al. Nat. Mater. 2013 for more information.
