PI-3 kinase-PTEN signaling node: an intercept point for the control of angiogenesis.

Journal Article (Journal Article;Review)

Angiogenesis is tightly regulated by opposing mechanisms in mammalian cells and is controlled by the angiogenic switch. Other review articles have described a central role for the PTEN/PI-3 kinase/AKT signaling node in the coordinate control of cell division, tumor growth, apoptosis, invasion and cellular metabolism [1, 2]. In this review, we focus on literature that supports the PTEN/PI-3 kinase/AKT signaling node as a major control point for the angiogenic switch in both the on and off positions. We also discuss the rationale for designing small molecule drugs that target the PTEN/PI-3 kinase/AKT signaling node for therapeutic intervention. Our hypothesis is that, instead of inhibiting one cell surface receptor, such as VEGFR2 with bevacizumab (Avastin), thereby leaving a significant number of receptors free to pulse angiogenic signals, a more effective strategy may be to regulate signaling through an intercept node where redundant cell surface receptor signals converge to transmit important signaling events within the cell. This therapeutic configuration brings coordinate control over multiple cell surface receptors in concert with a physiologic response which may combine arrest of cell cycle progression with growth inhibition and the induction of genes involved in specialized functions such as movement, which are all required for the complex process of angiogenesis to occur in a temporal-spatial paradigm.
