  • Title: Tumor metastasis and nm23: current concepts.
    Author: Steeg PS, Cohn KH, Leone A.
    Journal: Cancer Cells; 1991 Jul; 3(7):257-62. PubMed ID: 1911039.
    Abstract:
    Reduced expression and/or somatic allelic deletion of nm23 is associated with high metastatic potential in several types of rodent tumors and human breast and colorectal carcinomas. Transfection of murine nm23-1 cDNA into highly metastatic murine K-1735 TK melanoma cells results in a reduced incidence of primary tumor formation, significant reduction in tumor metastatic potential, and altered responsiveness to the cytokine, transforming growth factor beta. Here we discuss emerging concepts concerning nm23, such as its varied pattern of alteration/expression in tumor metastasis, its effect on tumorigenesis, and its possible biochemical functions.
