Lycopene may act on male hormones to fight cancer.

15/04/2004 - Lycopene, the carotenoid found in tomatoes, may reduce the risk of prostate cancer by inhibiting the male hormone’s effect on the prostate, report researchers from DSM this week, writes Dominique Patton.

Their analysis revealed that both nutrients affected gene expression directly in the tumours: lycopene interfered with local androgen activation by down-regulating 5-alpha-reductase, the key enzyme for the transformation of testosterone to its most active form dehydrotestosterone (DHT). As a consequence, the expression of androgen-regulated target genes was also reduced.
