Just how many astroturf groups did tobacco fund?

Thanks to the Tobacco documents we've learned how tobacco companies have secretly funded astroturf organizations like junkscience.com, secretly paid for think tanks to run political campaigns for them, and even created their own astroturf scientific journal. The latest pile of astoturf to be uncovered is detailed in a new paper by Anne Landman, Daniel Cortese and Stanton Glantz:

Vitamin D levels linked to breast cancer progression

Vitamin D levels linked to breast cancer progression

17/10/2006 - Increasing vitamin D levels may help curb the development and progression of breast cancer, suggests a small study from Imperial College London.

“This report, while being an observational study, clearly shows that circulating vitamin D levels are lower in patients with advanced breast cancer than in those with early breast cancer,” wrote lead author Dr Carlo Palmieri in the Journal of Clinical Pathology (doi.10.1136/jcp.2006.042747).

Both forms of the vitamin, D2 and D3, are hydroxylated in the liver and kidneys to form 25-hydroxyvitamin D, the non-active ‘storage' form, and 1,25-dihydroxyvitamin D, the biologically active form that is tightly controlled by the body. Scientists use serum 25- hydroxyvitamin D levels as a measure of vitamin D status.

This observation adds to an ever-growing body of evidence linking vitamin D status with incidence and risk of various cancers, including breast, colorectal and prostate. Indeed, the link between vitamin D intake and protection from cancer is not and dates from the 1940s when Frank Apperly demonstrated a link between latitude and deaths from cancer, and suggested that sunlight gave “a relative cancer immunity.”

Super chow, laced with semi-synthetic vitamin E derivative, inhibited spread of cancer in mice

Super chow, laced with semi-synthetic vitamin E derivative, inhibited spread of cancer in mice:

"PHILADELPHIA -- A chemically altered form of vitamin E mixed into mouse chow dramatically reduced spread of aggressive mammary cancer in mice, suggesting that the compound in pill form could be used to treat human metastatic cancer, according to a report in the October 1 issue of the journal Cancer Research."
