Involvement of an Actomyosin Contractile Ring in Saccharomyces cerevisiae Cytokinesis [PDF]
The Journal of Cell Biology, 1998 In Saccharomyces cerevisiae, the mother cell and bud are connected by a narrow neck. The mechanism by which this neck is closed during cytokinesis has been unclear. Here we report on the role of a contractile actomyosin ring in this process. Myo1p (the only type II myosin in S.

Force Generation and Contraction of Random Actomyosin Rings [PDF]
Biophysical Journal, 2015 Cytokinetic rings and stress fibers generate effective contraction, but how organized respective actomyosin arrays are, and how semi-random actomyosin bundles generate contraction is not clear.We investigate computationally the self-organization and contraction of an actomyosin ring that is completely disorganized initially. To this end, we formulate a

A dynamic microtubule cytoskeleton directs medial actomyosin function during tube formation [PDF]
, 2014 The cytoskeleton is a major determinant of cell-shape changes that drive the formation of complex tissues during development. Important roles for actomyosin during tissue morphogenesis have been identified, but the role of the microtubule cytoskeleton is

MPF governs the assembly and contraction of actomyosin rings by activating RhoA and MAPK during chemical-induced cytokinesis of goat oocytes. [PDF]
PLoS ONE, 2010 The interplay between maturation-promoting factor (MPF), mitogen-activated protein kinase (MAPK) and Rho GTPase during actin-myosin interactions has yet to be determined.

The role of the host—Neutrophil biology
Periodontology 2000, EarlyView., 2023 Abstract Neutrophilic polymorphonuclear leukocytes (neutrophils) are myeloid cells packed with lysosomal granules (hence also called granulocytes) that contain a formidable antimicrobial arsenal. They are terminally differentiated cells that play a critical role in acute and chronic inflammation, as well as in the resolution of inflammation and wound ...

Actomyosin Rings: The Riddle of the Sphincter [PDF]
Current Biology, 2002 Contractile rings consisting of actin filaments and myosin-2 have long been known to power cytokinesis, but recent work has shown that single-cell and multicellular actomyosin rings participate in processes ranging from wound healing to extrusion of apoptotic cells from epithelia.

Author response image 1. Actomyosin ring closure dynamics. [PDF]
, 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 ...

Regulation and Assembly of Actomyosin Contractile Rings in Cytokinesis and Cell Repair [PDF]
The Anatomical Record, 2018 ABSTRACT Cytokinesis and single‐cell wound repair both involve contractile assemblies of filamentous actin (F‐actin) and myosin II organized into characteristic ring‐like arrays. The assembly of these actomyosin contractile rings (CRs) is specified spatially and temporally by small Rho GTPases, which trigger local

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 ...
