    Phosphatidylinositol polyphosphates are very important in cellular signaling and have been shown to mediate a large number of physiological processes by attracting proteins to specific cellular sites. Phosphatidylinositol-(4,5)-bisphosphate is phosphorylated by phosphoinositide-3-kinase to produce Phosphatidylinositol-(3,4,5)-trisphosphate (PIP3).1 PIP3 is a second messenger that has a central role in cell growth, programmed cell death, spindle orientation control, and directed cell migrations such as chemotaxis. The Akt/PKB signaling pathway leads to cell survival and growth and is activated by PIP3. The PTEN protein regulates the Akt/PKB pathway by dephosphorylating PIP3. Many types of tumors show a mutation in the PTEN gene, showing a direct correlation between cancer and over expression of PIP32. PIP3 accumulates in the plasma membrane and acts as a site-specific receptor to recruit and activate proteins. It controls many cellular processes by generating internal calcium signals3 and it can directly modulate the activity of ion channels including the epithelial Na+ channel.4
