Expression of Phosphoinositide-specific phospholipase C enzymes in human osteosarcoma cell lines.

ABSTRACT: The definition of the number and nature of signal transduction pathways networking in the pathogenesis of osteosarcoma raised great interest. Intracellular calcium ions are important second messengers implicated in the control of cell death. The calcium concentration is regulated by signal transduction pathways, including the Phosphoinositides (PI) signaling. Phosphatydil inositol (4,5) bisphosphate (PIP2) is critical for many cellular activities. The levels of PIP2 are regulated by means of Phosphoinositide-specific Phospholipase C (PI-PLC) family of enzymes. We delineated the panel of expression of PI-PLC enzymes in four human osteosarcoma cell lines. In MG-63 cell line, PI-PLC β1, β2, β3, β4, γ1, γ2, δ1, δ3 and ε resulted expressed. In 143B cell line, PI-PLC β1, β2, β3, β4, γ1, γ2, δ1,
