Abstract
Clusterin (CLU) protein is widely distributed in animal tissues and is involved in many different processes, including apoptosis and neoplastic transformation. Green tea catechins (GTC) are known to exert chemopreventive effects in many cancer models, including transgenic adenocarcinoma mouse prostate (TRAMP) mice that spontaneously develop prostate cancer (CaP). In TRAMP mice, the CLU gene was dramatically down-regulated during onset and progression of CaP. In GTC-treated TRAMP mice in which tumor progression was chemoprevented, CLU mRNA and protein progressively accumulated in the prostate gland. CLU dropped again to undetectable levels in animals in which GTC chemoprevention failed and CaP developed.
