1 Nicotine-induced behavioral sensitization is associated with extracellular dopamine release and expression of c-Fos in the striatum and nucleus accumbens of the rat. Nicotine Fos proto-oncogene, AP-1 transcription factor subunit Rattus norvegicus
2 This study was carried out to investigate the neural mechanisms underlying nicotine-induced behavioral sensitization using in vivo microdialysis and Fos-like immunohistochemistry (FLI). Nicotine Fos proto-oncogene, AP-1 transcription factor subunit Rattus norvegicus
3 Furthermore, in parallel with the behavioral and biochemical data, systemic challenge with nicotine produced marked Fos-like immunohistochemistry in the nucleus accumbens and the striatum in the nicotine-pretreated rats. Nicotine Fos proto-oncogene, AP-1 transcription factor subunit Rattus norvegicus
4 Furthermore, in parallel with the behavioral and biochemical data, systemic challenge with nicotine produced marked Fos-like immunohistochemistry in the nucleus accumbens and the striatum in the nicotine-pretreated rats. Nicotine Fos proto-oncogene, AP-1 transcription factor subunit Rattus norvegicus
5 Taken together, this study demonstrates that behavioral sensitization is clearly associated with an increase in DA release and activation of Fos-like immunoreactive cells in the striatum and the nucleus accumbens produced by repeated nicotine treatment. Nicotine Fos proto-oncogene, AP-1 transcription factor subunit Rattus norvegicus
