Since previous studies have demonstrated that the c-jun gene is autoinduced by Jun/AP-1 , we also studied transcription of c-jun promoter (positions -132/+170)-reporter gene constructs with and without a mutated AP-1 element .
 DNA: AP-1 element; DNA: c-jun gene; DNA: c-jun promoter; protein: Jun/AP-1; DNA: c-jun; DNA: c-jun promoter (positions -132/+170)-reporter gene constructs
