Twelve of eighteen (66.7%) malignant tumor tissues showed greater than 10% nuclear staining, while benign tumor and hyperplastic tissues showed less than 10% nuclear staining. Higher nuclear expression of NF-κB was positively correlated with larger tumor size, lymph node metastasis and higher MI; however, no correlation was observed with distant metastasis and cyclin D1 expression. Higher NF-κB nuclear expression correlated with shorter patient survival. These findings suggest that NF-κB is a useful prognostic factor for canine MGT patients.}, pages = {713--718}, title = {Relationship between NF-κB Expression and Malignancy of Canine Mammary Gland Tumor Tissues}, volume = {74}, year = {2012} }
