The in vitro effects of Triton WR-1339 on lipid synthesis by bone cells

Triton WR-1339, administered parenterally, has long been known to be a potent hyperlipemic agent. In vitro lipid biosynthesis is stimulated in liver and brain preparations from animals injected with Triton. Only in a perfused isolated liver system has an in vitro effect of Triton on lipid synthesis been demonstrated. In the present study, lipid biosynthesis has been shown to increase in bone, a third organ system, under the influence of in vitro Triton WR-133. This stimulation affects most major lipid classes. Triton similarly stimulates lipid synthesis in tissue cultures of bone cells. This is the first report of an effect of Triton on lipid synthesis (1) in bone and (2) in any tissue culture system.
