To investigate the possible involvement of cytoskeletal components in antigen (Ag)-mediated activation of phospholipase D (PLD) in rat basophilic leukemia (RBL-2H3) cells, the effects of cytochalasin D, which is known to interfere with actin organization

Tumor stiffness is unrelated to myosin light chain phosphorylation in cancer cells. [PDF]
Many tumors are stiffer than their surrounding tissue. This increase in stiffness has been attributed, in part, to a Rho-dependent elevation of myosin II light chain phosphorylation.

Reversibility of cell surface label rearrangement [PDF]
Cell surface labeling can cause rearrangements of randomly distributed membrane components. Removal of the label bound to the cell surface allows the membrane components to return to their original random distribution, demonstrating that label is ...

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

The Relationship between fenestrations, sieve plates and rafts in liver sinusoidal endothelial cells. [PDF]
Fenestrations are transcellular pores in endothelial cells that facilitate transfer of substrates between blood and the extravascular compartment. In order to understand the regulation and formation of fenestrations, the relationship between membrane ...

Role of the cytoskeleton in laminin induced mammary gene expression [PDF]
The differentiation of rat mammary epithelial cells is characterized both by morphologic changes and by the expression of a group of milk protein genes. We have previously shown that by culturing these cells on the basement membrane glycoprotein laminin,

The role of the host—Neutrophil biology
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 ...

In vitro markers for virulence in Yersinia ruckeri [PDF]
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 ...

Cytochalasin D does not inhibit gravitropism in roots [PDF]
It is generally thought that sedimenting plastids are responsible for gravity sensing in higher plants. We directly tested the model generated by the current statolith hypothesis that the gravity sensing that leads to gravitropism results from an interaction between the plastids and actin microfilaments.

Src kinases regulate de novo actin polymerization during exocytosis in neuroendocrine chromaffin cells. [PDF]
The cortical actin network is dynamically rearranged during secretory processes. Nevertheless, it is unclear how de novo actin polymerization and the disruption of the preexisting actin network control transmitter release.
