Figure 10From: Hormone-induced protection of mammary tumorigenesis in genetically engineered mouse modelsCyclin D1 mRNA expression levels in mammary tumors arising in activated Her-2/neu mice. There was an approximately sixfold increase in the level of cyclin D1 in mammary tumors arising in control mice in comparison with tumors arising in hormone-treated mice. Results are expressed as means ± SEM.Back to article page
