p21-activated Kinase-1 Signaling Mediates Cyclin D1 Expression in Mammary Epithelial and Cancer Cells
1 Jan 2004
Abstract excerpt
p21-activated kinase 1 (Pak1) has been shown recently to induce hyperplasia in the mammary epithelium, a phenotype also manifested by overexpression of cyclin D1, a known indicator of the proliferative stage. Here we investigated the role of the Pak1 pathway in the expression of cyclin D1 using tissue culture models and transgenic mice expressing activated Pak1 in mammary glands. We found that hyperplastic...
