Elucidating the Role of CKS Proteins in Breast Cancer by Combining the Disciplines of Molecular Biology, Pathology, and Biophysics
Abstract
Breast cancer often occurs when the proteins that regulate normal epithelial cell division become dysregulated. This proposal examines the role of the cell cycle regulatory proteins, human cyclin-dependent kinase subunits (Cks1 and Cks2) in human breast cancer. The overexpression of Cks genes in breast tumor tissue and the role of Skp2 in tumorigenesis, suggests that Cks and Skp2 levels must be strictly regulated for proper cell cycling. We hypothesize that aberrant Cks protein expression and function contributes to breast carcinogenesis, at least in part, by its ability to interact with Skp2. In year one of this project, we have determined the levels of Cks mRNA and protein in (i) breast cancer cell lines and (ii) normal versus tumor breast tissue. We have also developed breast cancer cell lines that overexpress cks1, cks2, or skp2, and cells that co-overexpress cks1 and skp2. In the coming year, we will focus on characterizing the breast cancer cell lines developed that stably overexpress the aforementioned cell cycle proteins, using both in vitro and in vivo techniques.
