Implication

Experimental study demonstrates upregulated choline kinase and phospholipase C in ovarian cancer cells, indicating potential diagnostic imaging and therapeutic targets.

Key Points

To determine the enzymatic mechanisms driving the accumulation of phosphocholine in human epithelial ovarian cancer cells relative to non-tumoral counterparts.
Evaluated enzyme activity, protein content, and mRNA expression of phosphatidylcholine cycle enzymes in epithelial ovarian cancer cell lines, normal/non-tumoral immortalized cells, and patient tumor tissue.
Assessed changes in phosphocholine content and cell proliferation following pharmacological inhibition of phosphatidylcholine-specific phospholipase C with D609 in OVCAR3 and SKOV3 cell lines.
Ovarian cancer cells demonstrated a 12-fold to 25-fold activation of choline kinase, accompanied by elevated ChoKalpha mRNA and protein levels, alongside a 5-fold to 17-fold activation of phosphatidylcholine-specific phospholipase C.
Inhibition of phosphatidylcholine-specific phospholipase C by D609 induced a 30% to 40% reduction in phosphocholine content and blocked cancer cell proliferation.
Elevations in ChoKalpha mRNA, choline kinase protein, and phospholipase C protein levels were confirmed in surgical specimens from patients with epithelial ovarian cancer.
