“Analysis of signalling events by classical biochemical approaches is limited as the outcome is an averaged readout for protein activation of a single protein within a cell population.

This is a clear restriction when addressing signalling events in mixed populations or subpopulations of cells. By combining flow cytometry with a panel of phosphospecific antibodies against several signal molecules simultaneously in a multi-parameter phospho flow cytometry analysis it is possible to obtain a higher level of understanding of the signal transduction dynamics at a single cell level. In addition, analysis of mixed cell populations makes it possible to study cells ex vivo in a state more closely resembling the in vivo situation. The multimeric analysis yields information on combinations of signals turned on and off in specific settings such as disease (signal nodes) that can be used for biomarker analysis and for development of drug screening strategies. Prostaglandin E-2 (PGE(2)) is known to signal through four G-protein coupled transmembrane receptors, EP1-4, activating a multitude of potential signalling pathways. The analysis of

the PGE(2) signalling network elicited by activation of the four EP receptors in lymphoid cells revealing selleck kinase inhibitor several signalling nodes is reviewed as an example. (C) 2010 Elsevier Inc. All rights reserved.”
“Since the 1970s, the limitations of two dimensional (2D) cell culture and the relevance of appropriate three dimensional (3D) cell systems have become increasingly evident. Extensive effort has thus been made to move

cells from a flat world to a 3D environment. While 3D cell culture technologies are meanwhile widely used in academia, 2D culture technologies are still entrenched in the (pharmaceutical) industry for most kind of cell-based efficacy and toxicology tests. However, 3D cell culture technologies will certainly become more applicable if biological relevance, reproducibility and high throughput can be assured at acceptable costs. Most recent innovations and developments Epigenetics inhibitor clearly indicate that the transition from 2D to 3D cell culture for industrial purposes, for example, drug development is simply a question of time.”
“Endostatin is an endogenous inhibitor of angiogenesis. Although several endothelial cell surface molecules have been reported to interact with endostatin, its molecular mechanism of action is not fully elucidated. We used surface plasmon resonance assays to characterize interactions between endostatin, integrins, and heparin/heparan sulfate. alpha 5 beta 1 and alpha v beta 3 integrins form stable complexes with immobilized endostatin (K(D) = similar to 1.8 x 10(-8) M, two-state model).
