The existence of a nuclear polyphosphoinositol metabolism independent from that at the plasma membrane is now widely recognized. Specific changes in the nuclear phosphatidylinositol (Ptdlns) metabolism have been implicated in cell growth, differentiation, and neoplastic transformation. Here we shall review the main features of nuclear inositol lipid signaling through type I IGF receptor, focusing the attention on the role of inositide-specific phospholipase C (PI-PLC) beta1 in cell proliferation and differentiation, given its peculiar localization in the nuclear compartment.

Abstract
The existence of a nuclear polyphosphoinositol metabolism independent from that at the plasma membrane is now widely recognized. Specific changes in the nuclear phosphatidylinositol (Ptdlns) metabolism have been implicated in cell growth, differentiation, and neoplastic transformation. Here we shall review the main features of nuclear inositol lipid signaling through type I IGF receptor, focusing the attention on the role of inositide-specific phospholipase C (PI-PLC) beta1 in cell proliferation and differentiation, given its peculiar localization in the nuclear compartment.File in questo prodotto:
