Tilson HA, Emerich D, Bondy SC: Inhibition of ornithine decarboxylase alters neurological responsiveness to a tremorigen. Brain Res. 1986 Jul 30;379(1):147-50.
Difluoromethylornithine (DFMO), an inhibitor of ornithine decarboxylase (ODC; 200-800 mg/kg, s.c.), to rats has no detectable behavioral effects using a battery of tests to assess sensorimotor function. In contrast, the induction of tremor by chlordecone, a neurotoxic agent that affects neuronal ionic processes, is significantly attenuated by pretreatment with DFMO. The effects of DFMO on chlordecone-induced tremor were reversed by pretreatment with putrescine. DFMO had no effects on p,p'-DDT, a tremorigen having a mechanism of action different from chlordecone. These findings imply that polyamines may play a role in select neuronal processes. |
