On the dynamics of the microfilament system in HeLa cells [PDF]
We measured the pools of unpolymerized and filamentous actin in homogenates of HeLa cells made in several different lysis buffers, as well as after treatment of cells with a variety of chemicals or trypsin, and after adenovirus (type 2) infection.

Ultrafast imaging of cell elasticity with optical microelastography [PDF]
Elasticity is a fundamental cellular property that is related to the anatomy, functionality and pathological state of cells and tissues. However, current techniques based on cell deformation, atomic force microscopy or Brillouin scattering are rather slow and do not always accurately represent cell elasticity.

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

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

Effect of age and cytoskeletal elements on the indentation-dependent mechanical properties of chondrocytes. [PDF]
Articular cartilage chondrocytes are responsible for the synthesis, maintenance, and turnover of the extracellular matrix, metabolic processes that contribute to the mechanical properties of these cells.

Fractional calculus modeling of cell viscoelasticity quantifies drug response and maturation more robustly than integer order models [PDF]
It has recently been discovered that the viscoelastic properties of cells are inherent markers reflecting the complex biological states, functions and malfunctions of the cells. Although the extraction of model parameters from the viscoelasticity data of many cell types has been done successfully using integer order mechanical and power-law ...

Modulation of apoprotein E secretion in response to receptor-mediated endocytosis in resident and inflammatory macrophages. [PDF]
We have determined the effect of various endocytic ligands on the secretion of ApoE by macrophages. ApoE was a major secreted protein of resident macrophages, but BCG-activated macrophages secreted little ApoE and periodate-elicited macrophages secreted ...

The Cytochalasins and Polyketides from a Mangrove Endophytic Fungus Xylaria arbuscula QYF
Twelve compounds, including four undescribed cytochalasins, xylariachalasins A–D (1–4), four undescribed polyketides (5–8), and four known cytochalasins (9–12), were isolated from the mangrove endophytic fungus Xylaria arbuscula QYF. Their structures and
