Resumo |
Through the years, several studies reported the involvement of nuclear lipid signalling as highly connected with cell cycle progression. Indeed, nuclear Phosphatidylinositol-4,5-Biphosphate (PIP2) hydrolisis mediated by Phospholipases C (PLC), which leads to production of the second messengers Diacylglycerol (DAG) and Inositol-1,4,5-Triphosphate (IP3), is a fundamental event for both G1/S and G2/M checkpoints. In particular, we found that nuclear DAG production was mediated by PLCbeta1, enzyme mainly localized in the nucleus of K562 human erythroleukemia cells. This event triggered the activation and nuclear translocation of PKCalpha, which, in turn, resulted able to affect cell cycle via modulation of Cyclin D3 and Cyclin B1, two important enzymes for G1/S transition and G2/M progression respectively. |
