Lycopene slows human prostate tumour growth in mice and combined with vitamin E is even better
...hat we can use PSA values as a surrogate marker in short phase II/III human trials as it is clear that PSA values are accurately reflecting the inhibiting activity of the lycopene and vitamin E on tumour growth. "What was particularly marked was that it was the low dose of both lycopene and vitamin E that ...Scientists sequence genome of kind of organism central to biosphere's carbon cycle
