Reconstitution of Contractile FtsZ Rings in Liposomes

open access: yesScience, 2008
FtsZ is a tubulin homolog and the major cytoskeletal protein in bacterial cell division. It assembles into the Z ring, which contains FtsZ and a dozen other division proteins, and constricts to divide the cell. We have constructed a membrane-targeted FtsZ (FtsZ-mts) by splicing an amphipathic helix to its C terminus.

Septin filament compaction into rings requires the anillin Mid2 and contractile ring constriction

open access: yesCell Reports, 2022
Septin filaments assemble into high-order molecular structures that associate with membranes, acting as diffusion barriers and scaffold proteins crucial for many cellular processes. How septin filaments organize in such structures is still not understood.

The Role of the Contractile Ring during Cytokinesis [PDF]

open access: yesBiophysical Journal, 2012
Cytokinesis in animals and fungi involves constriction of an actomyosin contractile ring, but the constriction mechanisms and the role of the ring are not established. The constriction rate could be determined only by the properties and internal dynamics of the ring itself (a “dynamically autonomous” mechanism) as suggested by recent experiments on C ...

Cooperation between tropomyosin and α-actinin inhibits fimbrin association with actin filament networks in fission yeast

open access: yeseLife, 2019
We previously discovered that competition between fission yeast actin binding proteins (ABPs) for binding F-actin facilitates their sorting to different cellular networks.

Quantitative analysis of cytokinesis in situ during C. elegans postembryonic development. [PDF]

open access: yesPLoS ONE, 2014
The physical separation of a cell into two daughter cells during cytokinesis requires cell-intrinsic shape changes driven by a contractile ring. However, in vivo, cells interact with their environment, which includes other cells.

Stress generation and filament turnover during actin ring constriction. [PDF]

open access: yesPLoS ONE, 2007
We present a physical analysis of the dynamics and mechanics of contractile actin rings. In particular, we analyze the dynamics of ring contraction during cytokinesis in the Caenorhabditis elegans embryo.

Analyzing Contractile Ring Dynamics in Mid-Embryogenesis of C. Elegans

open access: yes, 2019
During cell division, a contractile ring made up of actin fibers, myosin motor ensembles, and cross linkers contracts to cleave one cell into two. How this large and complex molecular structure organizes and re-arranges as it constricts remains largely ...

Cyclic azapeptide CD36 ligand attenuates cardiac injury and reduces long‐chain fatty acid accumulation after myocardial ischemia–reperfusion in mice

open access: yesFEBS Open Bio, EarlyView.
In a murine model of myocardial ischemia and reperfusion (MI/R), the CD36 azapeptide ligand MPE‐298 reduces cardiac injury and transiently lowers left ventricular long‐chain fatty acids (LCFAs) accumulation 3 h after reperfusion, accompanied by a decrease of oxidative stress and inflammation‐associated genes' expression in the heart and adipose tissue.

An extracellular matrix protein promotes anillin-dependent processes in the Caenorhabditis elegans germline

open access: yesLife Science Alliance, 2019
The extracellular matrix protein Hemicentin (HIM-4) is an extracellular factor that regulates anillin (ANI-1) for germ cell membrane stabilization and contractile ring formation in C. elegans germline cells.
