Genomic and Proteomic Analysis of Mammary Tumors Arising in Transgenic Mice

Abstract
Transforming growth factor-β (TGF-β) is the prototype of a large family of signaling molecules. TGF-β signaling profoundly influences tumor development as demonstrated in several engineered mouse models. The present study was designed to identify differences by cDNA microarray and MALDI-TOF MS analyses in mammary carcinomas with and without TGF-β signaling. The results demonstrate a significant potential for combination of profiling technologies to further understand the molecular mechanisms of breast cancer.
