Antiproliferative and Cytotoxic Cytochalasins from Sparticola triseptata Inhibit Actin Polymerization and Aggregation

open access: yesJournal of Fungi, 2022
Laying the groundwork on preliminary structure–activity relationship study relating to the disruptive activity of cytochalasan derivatives on mammalian cell actin cytoskeleton, we furthered our study on the cytochalasans of the Dothideomycetes fungus ...

Myosin V and iNOS expression is enhanced in J774 murine macrophages treated with IFN-gamma [PDF]

open access: yesBrazilian Journal of Medical and Biological Research, 2001
Actin-based motor protein requirements and nitric oxide (NO) production are important features of macrophage activity during phagocytosis or microbicidal processes.

Phosphorylation of CLEC-2 is dependent on lipid rafts, actin polymerization,secondary mediators, and Rac [PDF]

open access: yes, 2010
The C-type lectin-like receptor 2 (CLEC-2)activates platelets through Src and Syk tyrosine kinases via a single cytoplasmic YxxL motif known as a hem immunoreceptor tyrosine-based activation motif (hemITAM).Here, we demonstrate using sucrose gradient ...

Cytochalasin B triggers a novel pertussis toxin sensitive pathway in TNF-alpha primed neutrophils

open access: yesBMC Cell Biology, 2004
Background Cytochalasin B does not directly activate the oxygen-radical-producing NADPH oxidase activity of neutrophils but transfers desensitized G-protein coupled receptors (GPCR) into an active signaling state by uncoupling GCPR from the cytoskeleton.

Occurrence and a possible mechanism of penetration of natural killer cells into k562 target cells during the cytotoxic interaction [PDF]

open access: yes, 1995
The cytotoxic interaction between cloned human Natural Killer (NK) cells and K562 target cells was studied using confocal laser scanning microscopy (CLSM) and conventional fluorescence microscopy.

Examination of actin and microtubule dependent APC localisations in living mammalian cells [PDF]

open access: yes, 2006
(provisional) Background The trafficking of the adenomatous polyposis coli (APC) tumour suppressor protein in mammalian cells is a perennially controversial topic. Immunostaining evidence for an actin-associated APC localisation at intercellular

YAP/TAZ regulates the expression of proteoglycan 4 and tenascin C in superficial-zone chondrocytes [PDF]

open access: yesEuropean Cells & Materials, 2020
The roles of cell division control protein 42 homologue (CDC42) and actin polymerisation in regulating the phenotype of superficial-zone chondrocytes (SZCs) have been demonstrated in vitro; however, the signalling pathway(s) downstream have yet to be ...

In vitro markers for virulence in Yersinia ruckeri [PDF]

open access: yes, 2010
In this study, different traits that have been associated with bacterial virulence were studied in Yersinia ruckeri. Two isolates that had been shown to cause disease and mortality in experimentally infected rainbow trout were compared with five ...

A pharmacological cocktail for arresting actin dynamics in living cells. [PDF]

open access: yes, 2011
The actin cytoskeleton is regulated by factors that influence polymer assembly, disassembly, and network rearrangement. Drugs that inhibit these events have been used to test the role of actin dynamics in a wide range of cellular processes.
