The v-jun oncogene was initially identified as the causative agent for fibrosarcomas in chickens. Studies show that overexpression of v-Jun proteins transforms chicken embryo fibroblasts (CEF) in vitro, and forms tumors in chickens in vivo. The mechanisms for this are not clearly defined. Conceivably, overexpression of an unregulated transcription factor would cause cell transfonnation by illicit regulation of its target genes. In support of this, we show that in vivo v-Jun complexes exhibit differential binding to in vitro generated AP-1 and 'AP-1 like' target sequences, suggesting that the pattern of target gene expression is altered during cell transformation. …
