Cyclosporin A differentially inhibits multiple steps in VEGF induced angiogenesis in human microvascular endothelial cells through altered intracellular signaling - Rafiee, Parvaneh; Heidemann, Jan; Ogawa, Hitoshi; Johnson, Nathan A; Fisher, Pamela J; Li, Mona S; Otterson, Mary F; Johnson, Christopher P; Binion, David G
The immunosuppressive agent cyclosporin A (CsA), a calcineurin inhibitor which blocks T cell activation has provided the pharmacologic foundation for organ transplantation. CsA exerts additional effects on non-immune cell populations and may adversely effect microvascular endothelial cells, contributing to chronic rejection, a long-term clinical complication and significant cause of mortality in solid-organ transplants, including patients with small bowel allografts. Growth of new blood vessels, or angiogenesis, is a critical homeostatic mechanism in organs and tissues, and regulates vascular populations in response to physiologic requirements. We hypothesized that CsA would inhibit the angiogenic capacity of human gut microvessels. Primary cultures of...

Mitogen Activated Protein kinase signal transduction pathways in the prostate - Maroni, Paul D; Koul, Sweaty; Meacham, Randall B; Koul, Hari K
The biochemistry of the mitogen activated protein kinases ERK, JNK, and p38 have been studied in prostate physiology in an attempt to elucidate novel mechanisms and pathways for the treatment of prostatic disease. We reviewed articles examining mitogen-activated protein kinases using prostate tissue or cell lines. As with other tissue types, these signaling modules are links/transmitters for important pathways in prostate cells that can result in cellular survival or apoptosis. While the activation of the ERK pathway appears to primarily result in survival, the roles of JNK and p38 are less clear. Manipulation of these pathways could have important implications...

APC: the toll road to continued high quality communication - Perbal, Bernard
In this article we briefly review the reasons and advantages that underly our publisher's decision to introduce article-processing charges (APC) for manuscripts submitted to Cell Communication and Signaling. The charge is an attempt to develop a new business model for distributing biomedical information and has been accepted in a number of other journals. APCs will enable BioMed Central to continue to provide their excellent service and will help to establish our journal.

The STATs in cell stress-type responses - Dudley, Andrew C; Thomas, David; Best, James; Jenkins, Alicia
In the early 1990's, a new cell signaling pathway was described. This new paradigm, now known as the JAK/STAT pathway, has been extensively investigated in immune-type cells in response to interferons and interleukins. However, recent evidence suggests that the JAK/STAT pathway also mediates diverse cellular responses to various forms of biological stress including hypoxia/reperfusion, endotoxin, ultraviolet light, and hyperosmolarity. The current literature describing the JAK/STAT pathway's role in cellular stress responses has been reviewed herein, but it is clear that our knowledge in this area is far from complete.

Recognizing scientific excellence in the biology of cell adhesion - Wary, Kishore K
The prestigious 2005 Japan Prize for Cell Biology has been awarded to Dr. Masatoshi Takeichi, Director of RIKEN Developmental Biology, Kobe, Japan, and Dr. Erkki Ruoslahti, Distinguished Professor, The Burnham Institute, La Jolla, USA for their "Fundamental contribution in elucidating the molecular mechanisms of cell adhesion". The award is scheduled to be presented to the scientists in ceremonies in Tokyo on April 20, 2005 as part of a week-long celebration of "Japan Prize Week".
