High level expression of p27 ^kip1 and cyclin D1 in some human breast cancer cells: Inverse correlation between the expression of p27 ^kip1 and degree of malignancy in human breast and colorectal cancers

Abstract excerpt

The expression of cyclin-dependent kinase inhibitor p27(kip1) in human tumors and normal tissues was investigated using a panel of novel anti-p27(kip1) mAbs. An inverse correlation between expression of p27(kip1) and cell proliferation was generally observed after analyzing its expression in 25 different normal human tissues. In some highly proliferative human breast cancer cells, however, high level p27(kip1)...
