Early cell cycle diacylglycerol (DAG) content and protein kinase C (PKC) activity enhancement potentiates prostaglandin F2α (PGF2α) induced mitogenesis in Swiss 3T3 cells

R59022, a diacylglycerol kinase inhibitor, enhances the prostaglandin F2α (PGF2α)-induced diacylglycerol (DAG) synthesis in Swiss 3T3 cells. It also potentiates the PGF2α-mediated protein kinase C (PKC)-dependent 80 kDa protein (80K) phosphorylation and initiation of DNA replication. R 59022 enhance...
