title: Inhibition of NGF-induced neurite outgrowth of PC12 cells by Bacillus cereus sphingomyelinase, a bacterial hemolysin.
abstract: Sphingomyelinase of Bacillus cereus, a bacterial hemolysin, reduced nerve growth factor (NGF)-induced neurite outgrowth of PC12 cells in a dose-dependent manner. At 200 mU/ml, sphingomyelinase repressed half the neurite outgrowth of the cells at 250 ng/ml NGF. The c-fos superinduction, one of the early responses induced by NGF, was not influenced by this treatment, suggesting that the repression by sphingomyelinase occurred via a protein kinase C-independent pathway.
