PTTG binding factor (PBF) is a poorly characterised 22 kDa protein that is implicated in the aetiology of pituitary and thyroid tumours. Our recent investigations have attempted to discern the function of PBF in vitro. In particular, we reported that PBF can inhibit the activity of the sodium iodide symporter (NIS), which is responsible for iodide uptake into thyroid cells. However, little is known about the precise role of PBF in vivo. We have now generated a mu...

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 ...
