Journal ArticleDOI
Force activates smooth muscle α-actin promoter activity through the Rho signaling pathway
Xiao-Han Zhao,Carol Laschinger,Pam Arora,Katalin Szászi,Andras Kapus,Christopher A. McCulloch +5 more
TL;DR: Mechanical forces mediate actin assembly through the Rho–Rho-kinase–LIMK cofilin pathway, which promotes nuclear translocation of MRTF and subsequent activation of the SMA promoter to enhance SMA expression in fibroblasts.
Journal ArticleDOI
The Role of Actin-binding Protein 280 in Integrin-dependent Mechanoprotection
Michael Glogauer,Pam Arora,Deborah Chou,Paul A. Janmey,Gregory P. Downey,Christopher A. McCulloch +5 more
TL;DR: It is demonstrated that by a calcium-dependent mechanism, human fibroblasts reinforce locally their connection with extracellular adhesion sites by inducing actin assembly and by recruiting actin-binding protein 280 (ABP-280) into cortical adhesion complexes.
Journal ArticleDOI
Cytokinesis requires localized β-actin filament production by an actin isoform specific nucleator.
TL;DR: The authors show that the stabilization and organization of the cytokinetic furrow requires localized β-actin filament assembly at the site of cytokinesis by an actin isoform specific nucleator.
Journal ArticleDOI
The scaffold-protein IQGAP1 enhances and spatially restricts the actin-nucleating activity of Diaphanous-related formin 1 (DIAPH1).
Anan Chen,Pam Arora,Christine Chieh-Lin Lai,John W. Copeland,Trevor F. Moraes,Christopher A. McCulloch,Brigitte D. Lavoie,Andrew Wilde +7 more
TL;DR: Results indicate that IQGAP1 enhances RhoA-mediated activation of DIAPH1 in vivo and helps ensure the spatio-temporal regulation of actin nucleation to stimulate robust and localized actin filament production in vivo.
