摘要
The type III transforming growth factor-beta receptor (TGF beta R3, betaglycan), a tumour suppressor, is the most frequently lost TGF beta pathway component. This event appears to be very important in the transition of the TGF beta pathway from having tumour-suppressor activity in early prostate tumour development, to having tumour-promoting activity in metastatic disease. Moreover, loss of the TGF beta R3 can also affect the cellular response towards testosterone, inhibin/activin, and dysregulate growth-factor pathways that mediate growth and angiogenesis. In this review we discuss how TGF beta R3 normally functions as an accessory protein in the TGF beta pathway, how its loss is related to tumour progression, and the treatment implications of TGF beta R3 loss in individuals with prostate cancer.
