Identification and Cloning a Novel Tumor Suppressor Gene in Breast Cancer
Abstract
On the basis of an extensive body of cytogenetic literature as well as molecular evidence from our laboratory, we hypothesize that a tumor suppressor gene is located on the long arm of Human Chromosome 7 at the q31.1 band. Furthermore, we propose that inactivation of this tumor suppressor gene plays a role in the development of breast cancer. The long term objectives of the study are to identify and clone the tumor suppressor gene and to determine its function. The objectives for the requested funding period are to provide functional evidence for the existence of this tumor suppressor gene in breast cancer using microcell fusion and to clone the DNA fragment containing the putative tumor suppressor gene using a novel approach based on the introduction of Yeast Artificial Chromosomes (YACs) into breast cancer cells. This novel approach will facilitate the cloning of putative tumor suppressor genes closing the technical gaps that exist between the identification of deleted regions of genome containing putative tumor suppressor genes and the actual cloning of DNA fragments containing the candidate genes.
