The Tumor Suppressor Protein p53 and its Physiological Splicing Variant p53as in a Mouse Mammary Cancer Model

Authors: Molly Kulesz-Martin; HEALTH RESEARCH INC BUFFALO NY
Abstract:
The proposed studies seek to explore cellular and molecular aspects of p53 function that may contribute to the development and progression of breast cancer. The hypotheses are: (1) that p53 and a novel physiological splicing variant, p53as, have distinct stability in cells, distinct expression during the cell cycle, and distinct associated proteins; (2) that p53as has different specificity or affinity for DNA binding sequences than p53; and (3) that p53 and p53as mRNA and protein are differentially expressed in mouse mammary preneoplastic and neoplastic cells and tissues with implications for breast cancer detection, prognosis or treatment.
