The prognosis of breast cancer patients is related to the degree of metastasis. However, the
mechanisms by which epithelial tumor cells escape from the primary tumor and colonize at a
distant site are not entirely understood. Here, we analyzed expression levels of pituitary
tumor-transforming gene-1 (PTTG1), a relatively uncharacterized oncoprotein, in patient-
derived breast cancer tissues with corresponding normal breast tissues. We found that
PTTG1 is highly expressed in breast cancer patients, compared with normal tissues. Also …
