Sulforaphane may protect the joints from exercise damage and arthritis by raising Phase-2 detoxification enzymes

Heavy exertion can cause the joints to release COX-2 enzymes. This triggers pain and inflammation
in the joint that inhibits the activity of Phase-2 detoxification enzymes. This can kill chondrocytes
cells, the cells that produce cartilage for the joint. When chondrocytes stop functioning arthritis
can develop. In this study, researchers at Johns Hopkins University added Sulforaphane to chondrocytes
taken from human joints. After a day the cells were subjected to a stress test designed to mimic the
effects of heavy exertion on the chondrocytes. The Sulforaphane raised the level of Phase-2
detoxification enzymes, and these beneficial enzymes prevented the activation of the inflammatory
COX-2 enzyme. The Sulforaphane prevented the death of these all important chondrocytes. COX-2
inhibiting drugs block the COX-2 enzyme and reduce inflammation and pain. However, with these
drugs the COX-2 enzyme is stockpiled and as soon as the drug is discontinued the stockpiled COX-2
enzyme resumes damaging the joint. Unlike the COX-2 inhibiting drugs, Sulforaphane doesn't cause a
stockpile, but instead stop the increasing activity of the inflammatory and damaging COX-2 enzyme.
The study is published in the September27th issue of the Proceedings of the National Academy of
Sciences.

Sulforaphane may fight prostate cancer
In this study human prostate cancer cells were exposed to Sulforaphane. Exposing the prostate cancer
cells to Sulforaphane for 24 hours or more significantly decreased the number of viable cells. The
Sulforaphane inhibited the growth cycle of the prostate cancer cells and called into action cellular
executioners known as caspaces that caused the death and destruction of the cancerous cells. The
study is published in the current issue of the bimonthly journal Cancer and Nutrition.
More evidence that EGCG (from Green Tea) helps fight obesity
Mice were over fed with a high-fat diet; naturally the mice developed obesity and EGCG (from
Green Tea) was supplemented in the diet. Adding EGCG decreased the accumulation of fat, and the
higher the concentration of EGCG the less fat the mice stored. The study is published in the
June 2005 issue of the International Journal of Obesity.
