| Research Abstract |
We previously reported that excessive nitric oxide (NO) was generated by neuronal NO synthase (nNOS) which is persistently increased in the generalized epilepsy model of pentylenetetrazole (PTZ)-induced kindling rodents, which is caused by abnormal neuronal activity. In this study, we characterized a novel posttranslational modification in nNOS by small ubiquitin-related modifier (SUMO) which regulates protein stability, activity and localization. In addition, we found that the threshold of PTZ-induced convulsive seizure was defined by the NO levels in various brain regions of mice.
