Project description:The integral role of p53 in tumor suppression has promted many laboratories to perform extensive analyses of signaling pathways downstream of the p53 family of sequence-specific DNA binding transcription factors (p53 and its homologs p63 and p73). Despite the ability of p73 to regulate many p53 family target genes, little is known about the specific pathways that modulate p73 during development, tumorigenesis and tumor therapy. In this study we present a gene signature-based approach for connecting signaling pathways to transcription factors, as exemplified by p73. We generated a p73 gene signature by integrating whole-genome chromatin immunoprecipitation and expression profiling. Experiment Overall Design: H1299 lung carcinoma cells were infected with p73 expressing or control adenovirus for 5 h and then harvested.

We generated a p73 gene signature by integrating whole-genome chromatin immunoprecipitation and expression profiling. Experiment Overall Design: H1299 lung carcinoma cells were transduced with TAp73beta or GFP expressing adenoviruses. Microarray analysis (on the GFP and TAp73beta samples) and ChIPSeq analysis (on the TAp73beta sample) were performed to identify candidate p73 target genes.

Project description:The p53-family member p73 functions in various cellular signaling pathways and can have tumor suppressor properties. Several isoforms of p73 exist that differ considerably in their function. Whereas the functions of the N-terminal isoforms (TA and M-NM-^TNp73) and their opposing pro- and anti-apoptotic roles became evident, the functional differences of the distinct C-terminal spliceforms of TAp73 have remained unclear. Here, we characterized the genomic binding sites for TAp73M-NM-1 and TAp73M-NM-2 and identified a specific p73 consensus binding-motif. Furthermore, an AP1 motif is strongly enriched close to binding sites for TAp73M-NM-1. These AP1 motif-containing target genes are selectively upregulated by TAp73M-NM-1, while their mRNA expression is repressed upon TAp73M-NM-2 induction. Recruitment of c-Jun to the respective AP1 sites was impaired upon TAp73M-NM-2 expression in part due to downregulation of c-Jun. We show that several of these AP1-site containing TAp73M-NM-1-induced genes reduce on apoptosis-induction suggesting an underlying molecular mechanism for the observed functional differences between TAp73M-NM-1 and TAp73M-NM-2.
