May 30, 2006 -- The anti-cancer effects of exercise are due to
increases in a protein that blocks cell growth and induces cell death,
according to Australian researchers.
The protein, IGFBP-3, inhibits another protein, IGF-1, thereby blocking
IGF-1's proliferative effect on cell growth, the study suggests.

Dr. Andrew Haydon and colleagues at Monash Medical School in Melbourne
found that among study subjects who were physically active, an increase
in IGFBP-3 was associated with a 48 percent reduction in colon
cancer-specific deaths.

IGF-1 has been shown to stimulate cell growth and promote the formation
of new blood vessels, which tumors need to grow.
