title: Induction of differentiation in murine neuroblastoma cells by mevinolin, a competitive inhibitor of 3-hydroxy-3-methylglutaryl coenzyme A reductase.
abstract: Mevinolin, a competitive inhibitor of 3-hydroxy-3-methylglutaryl coenzyme A reductase, stimulated outgrowth of neurites and increased acetylcholinesterase activity in C1300-N2A murine neuroblastoma cells cultured in medium containing 10% fetal calf serum. Changes in cell morphology and enzyme activity were concentration-dependent in the range of 0.25-25 microM mevinolin, and were accompanied by decreased incorporation of [3H]thymidine into DNA. The expression of differentiated characteristics induced by 25 microM mevinolin was blocked by simultaneous addition of 100 microM mevalonate to the culture medium. The data suggest that changes in intracellular levels of mevalonate or one of its isoprenoid derivatives may play a role in the regulation of cell differentiation.
