The regulation of calcium concentration triggers physiological events in all cell types. Unregulated elevation in calcium concentrations is often cytotoxic. In fact, uncontrolled calcium levels alter proteins’ function, apoptosis regulation, as well as proliferation, secretion and contraction. Calcium levels are tightly regulated. A great interest was paid to signal transduction pathways for their role in mammalian reproduction. The role of phosphoinositide (PI) signal transduction pathway and related phosphoinositide-specific phospholipase C (PI-PLC) enzymes in the regulation of calcium levels was actively studied and characterized.

In the present review the role of PI, the expression of selected PI-PLC enzymes and the crosstalk with further signaling systems in the endometrium will be discussed.

Abstract
The regulation of calcium concentration triggers physiological events in all cell types. Unregulated elevation in calcium concentrations is often cytotoxic. In fact, uncontrolled calcium levels alter proteins’ function, apoptosis regulation, as well as proliferation, secretion and contraction. Calcium levels are tightly regulated. A great interest was paid to signal transduction pathways for their role in mammalian reproduction. The role of phosphoinositide (PI) signal transduction pathway and related phosphoinositide-specific phospholipase C (PI-PLC) enzymes in the regulation of calcium levels was actively studied and characterized. However, the role of PI signaling and PI-PLC enzymes in the endometrium is far to be completely highlighted. In the present review the role of PI, the expression of selected PI-PLC enzymes and the crosstalk with further signaling systems in the endometrium will be discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
