Curry spice component may help slow prostate tumor growth

Curcumin, an active component of the Indian curry spice turmeric, may help slow down tumor growth in castration-resistant prostate cancer patients on androgen deprivation therapy (ADT), a study from researchers at Thomas Jefferson University's Kimmel Cancer Center suggests. Researchers observed in a pre-clinical study that curcumin suppresses two known nuclear receptor activators, p300 and CPB (or CREB1-binding protein), which have been shown to work against ADT. ADT aims to inhibit the androgen receptor -- an important male hormone in the development and progression of prostate cancer -- in patients. But a major mechanism of therapeutic failure and progression to advanced disease is inappropriate reactivation of this receptor. Sophisticated tumor cells, with the help of p300 and CPB, sometimes bypass the therapy. Thus, development of novel targets that act in concert with the therapy would be of benefit to patients with castration-resistant prostate cancer.
