Research Keywords
cancer, p53, p63, p73, gene regulation, breast cancer, tumor suppression, epithelial cell differentiation

Research Specialty
p53 family signaling axis (p53, p63, and p73); Breast Cancer; Mechanisms of tumor suppression and epithelial cell differentiation

Research Description
Some defining properties of tumor cells are increased cell proliferation, decreased cell death and genomic instability. These characteristics are acquired as a consequence of mutations in genes that control the fidelity and frequency of cell division as well as the ability of the cell to initiate pathways of apoptosis. A goal of the ongoing cancer-based research in the Pietenpol Laboratory is to provide new therapeutic approaches that specifically target the molecular interactions and biochemical pathways that are changed in tumor cells. The Laboratory was one of the first to pioneer chromatin immunoprecipatation techniques allowing analysis of p53 and identification of target genes involved in tumor suppression. They discovered that p63 signaling confers key epithelial properties to cells by regulating novel target genes and transcriptional programs controling mesenchymal phenotypes. Subsequently, the Pietenpol group began mechanistic studies on p73, deciphered the functional p73 binding sites in the genome, discovered numerous p73-target mRNAs and microRNAs, and was the first to link the mTOR signaling pathway to regulation of p73 activity. Importantly, the research defined a mTOR-p73 signaling pathway involved in mesenchymal differentiation and a resulting p73 gene signature that classifies rhabdomyosarcomas by subtype and patient outcome. Most recently, Pietenpol and her team have integrated research expertise in tumor suppressor genes and molecular genetics with bioinformatic analysis of high dimensional genomic data sets to molecularly subtype difficult-to-treat, triple negative breast cancer. The results are being translated to clinical trials and alignment of patients to appropriate, molecularly targeted therapy. The overall goals of her research are to use bench-based discoveries to advance patient care.
