Cytokinesis in trypanosomes.

, 2012
Cytokinesis is a crucial step in the cell division cycle whereby the cell membrane and underlying cortex is remodelled and drawn together to create two new daughter cells.

Rap1-dependent pathways coordinate cytokinesis in Dictyostelium [PDF]

, 2014
Cytokinesis is the final step of mitosis when a mother cell is separated into two daughter cells. Major cytoskeletal changes are essential for cytokinesis; it is, however, not well understood how the microtubules and actomyosin cytoskeleton are exactly ...

Cytotoxic and Genotoxic Effects in Buccal Cells of Sandstone Quarry Workers

Journal of Applied Toxicology, EarlyView.
ABSTRACT Mineral extraction poses significant occupational health risks, particularly from respirable crystalline silica exposure. Sandstone quarrying generates substantial dust, yet evidence of its genotoxic effects remains limited. This study investigated cytogenotoxic damage in sandstone quarry workers from southern Brazil using the buccal ...

Importin-binding Regulates Contractile Proteins for Cytokinesis [PDF]

, 2020
Cytokinesis, the last step of mitosis, describes the physical separation of a cell into two daughters. In metazoan cells, a contractile ring composed of actin and myosin forms at the division plane and constricts the plasma membrane of the cell.

In planta analysis of the mode of action of cinmethylin and confirmation of fatty acyl‐ACP thioesterases (FATs) as primary site of action

Pest Management Science, EarlyView.
In planta analysis of the mode of action of cinmethylin and confirmation of fatty acyl‐ACP thioesterases (FATs) as primary site of action. Cinmethylin inhibits FATs, disrupting eukaryotic de novo lipid biosynthesis and causing defects in cell division, elongation and integrity. We confirm FATs as the primary site of action in planta.

Cortical flow aligns actin filaments to form a furrow

eLife, 2016
Cytokinesis in eukaryotic cells is often accompanied by actomyosin cortical flow. Over 30 years ago, Borisy and White proposed that cortical flow converging upon the cell equator compresses the actomyosin network to mechanically align actin filaments ...

Divide and ProsPer: The emerging role of PtdIns3P in cytokinesis

, 2010
Cytokinesis is the final step of cell division whereby the dividing cells separate physically. Failure of this process has been proposed to cause tumourigenesis. Several specific lipids are essential for cytokinesis, and recent evidence has revealed that

Identification of Yeast Protein Sequences With Similarity to the ESCRT‐III Protein Snf7

Yeast, EarlyView.
ABSTRACT Endosomal sorting complex required for transport (ESCRT‐III) is a membrane remodeling complex involved in a large number of cellular processes. It appears to perform an essential function in eukaryotes, since to date no eukaryotic organism completely devoid of ESCRT‐III has been found.

Very-long-chain fatty acids are required for cell plate formation during cytokinesis in Arabidopsis thaliana

, 2011
Acyl chain length is thought to be crucial for biophysical properties of the membrane, in particular during cell division, when active vesicular fusion is necessary.

Robust gap repair in the contractile ring ensures timely completion of cytokinesis [PDF]

, 2016
Cytokinesis in animal cells requires the constriction of an actomyosin contractile ring, whose architecture and mechanism remain poorly understood. We use laser microsurgery to explore the biophysical properties of constricting rings in Caenorhabditis ...
