A Commentary on “TGF-β1-Induced Expression of the Anti-Apoptotic PAI-1 Protein Requires EGFR Signaling”     (07/Sep/2009)


Plasminogen activator inhibitor-1 (PAI-1) has been found to affect a number of important cell processes and therefore abnormal expression of PAI-1 has been associated with a number of diseases and disorders. Understanding the transactivation of PAI-1 may result in identifying novel therapeutic targets.

TGF-β1 -Induced Expression of the Anti-Apoptotic PAI-1 Protein Requires EGFR Signaling     (11/Jun/2009)


TGF-β1 and its target gene encoding plasminogen activator inhibitor-1 (PAI-1) are major regulators of capillary outgrowth, vessel maturation and angiogenic network stability. The increasing realization of the complexity of PAI-1 action in the vascular system requires analysis of specific signaling events that impact its expression in a physiologically-relevant cell system. PAI-1 was required for tubular differentiation and maintenance of cellular survival in complex gels since targeted disruption of PAI-1 synthesis or activity with antisense constructs...

New Functions for Oxysterols and Their Cellular Receptors     (28/Jun/2008)


Vesa M. Olkkonen National Public Health Institute and FIMM, Institute for Molecular Medicine Finland, Biomedicum, Helsinki, Finland. Abstract Oxysterols are naturally occurring oxidized derivatives of cholesterol, or by-products of cholesterol biosynthesis, with multiple biologic functions. These compounds display cytotoxic, pro-apoptotic, and pro-inflammatory activities and may play a...

The Role of Glucose Metabolism and Glucose-Associated Signalling in Cancer     (18/Jan/2008)


Aggressive carcinomas ferment glucose to lactate even in the presence of oxygen. This particular metabolism, termed aerobic glycolysis, the glycolytic phenotype, or the Warburg effect, was discovered by Nobel laureate Otto Warburg in the 1920s. Since these times, controversial discussions about the relevance of the fermentation of glucose by tumours...
