Introduction: The human Pituitary Tumor Transforming Gene (hPTTG) is a phosphorylated proto-oncogene induced in multiple tumour types. hPTTG phosphorylation is mediated by cyclin-dependent kinase 2 (CDC2) and expression is regulated by specificity protein 1 (SP1). In thyroid cancer, hPTTG induces genetic instability and propagates growth through induction of growth factors (GFs).Methods: The interplay between hPTTG phosphorylation, SP1 regulation and GF ...
