Enhanced expression of an insulin growth factor-like binding protein (mac25) in senescent human mammary epithelial cells and induced expression with retinoic acid.

Abstract excerpt

mac25, the subject of this report, was selected by the differential display of mRNA method in a search for genes overexpressed in senescent human mammary epithelial cells. mac25 had previously been cloned as a discrete gene, preferentially expressed in normal, leptomeningial cells compared with meningioma tumors. mac25 is another member of the insulin growth factor-binding protein (IGFBP) family. Insulin-like...
