While scaffold proteins are thought to be key components of signaling pathways, their exact function is unknown. By preassembling multiple components of signaling cascades, scaffolds are predicted to influence the efficiency and/or specificity of signaling events. Here we analyze a
Since we recently demonstrated that high-density lipoprotein induced human coronary artery endothelial cell (HCEC) tube formation through Ras/Raf/ERK (extracellular-signal-regulated kinase) activation [Arterioscler. Thromb. Vasc. Biol. 23 (2003) 802], it is possible that lipid-lowering agents such as statins, which reduce the

Interleukin 1beta (IL-1beta) suppresses the IL-6-dependent induction of type II acute-phase response genes, but the underlying mechanism for this suppression remains uncertain. Here we report that treatment of human hepatocullular carcinoma HepG2 cells with IL-1beta inhibited the IL-6-dependent binding of
Accurate measurement of activity of wild-type K-ras protein is important due to its tumor suppressor action in tissues such as lung. A published method by Taylor and co-workers uses plasmid-containing Escherichia coli cells to produce a glutathione-S-transferase/raf-1 ras binding domain

Since we recently reported that high density lipoprotein, which contains the bioactive lipid sphingosine-1-phosphate (S1P) [Arterioscler. Thromb. Vasc. Biol. 23 (2003) 802], induced human coronary artery endothelial cell (HCEC) tube formation mediated by a Ras/Raf/ERK (extracellular signal-activated kinase) pathway, we
Probiotics exhibit an inhibitory effect on pathogens, help prevent chronic intestinal inflammatory diseases or atopic syndromes, and support the immune system.
Today, diverse studies report the benefits of probiotics, such as inhibitory effects on pathogens, aid in the management or prevention of chronic intestinal inflammatory diseases or atopic syndromes, and support to the immune system. Potential beneficial applications abound, researchers continue to evaluate the effictiveness and clarify the mechanisms of action of probiotics.
