E2F1 induces pituitary tumor transforming gene (PTTG1) expression in human pituitary tumors.


Rb/E2F is dysregulated in murine and human pituitary tumors. Pituitary tumor transforming gene (PTTG1), a securin protein, is required for pituitary tumorigenesis, and PTTG1 deletion attenuates pituitary tumor development in Rb(+/-) mice. E2F1 and PTTG1 were concordantly overexpressed in 29 of 46 Rb(+/-) murine pituitary tissues and also in 45 of 80 human… (More)
