Vitamin E: gamma-Tocopherol may have dangerous effect on cells
Researchers at Ohio State University studied how two forms of vitamin E act once they are inside animal cells.
In the past couple of decades, a slough of studies has looked at the benefits of vitamin E and other antioxidants. While a considerable amount of this research touts the advantages of consuming antioxidants, some of the studies have found that in certain cases, antioxidants, including vitamin E, may actually increase the potential for developing heart disease, cancer and a host of other health problems.
This study provides clues as to why this could happen, say Jiyan Ma and his colleague David Cornwell, both at Ohio State.
The two men led a study that compared how the two most common forms of vitamin E, one is found primarily in plants like corn and soybeans, while the other is found in olive oil, almonds, sunflower seeds and mustard greens, affect the health of animal cells.
The main difference between the two forms is a slight variation in their chemical structures.
In laboratory experiments, the kind of vitamin E found in corn and soybean oil, gamma-Tocopherol, ultimately destroyed animal cells. But the other form of vitamin E, alpha-Tocopherol, did not.
" In the United States we tend to eat a diet rich in corn and soybean oil, so we consume much greater amounts of gamma-Tocopherol than alpha-Tocopherol," Cornwell said. " But most of the vitamin E coursing through out veins is alpha-Tocopherol – the body selects for this version. We want to know why that is, and whether the selection of the alpha-Tocopherol confers an evolutionary benefit in animal cells."
The study is published in the Proceedings of the National Academy of Sciences ( PNAS ).
The researchers conducted laboratory experiments on cells taken from the brains of mice.
They treated some of the cells with metabolic end products, called quinones, of alpha- and gamma-Tocopherol.
When the body breaks down vitamin E, these end products are what enter and act on our cells. However, Ma said that our bodies get rid of most gamma-Tocopherol before it ever has a chance to reach its quinone stage.
Using laboratory techniques that allowed them to detect the activity of the quinones inside the cells, the researchers found that the gamma-Tocopherol quinone formed a compound which destroyed that cell. It did so by preventing proper protein folding in the cells, which causes a cellular response that is involved in a variety of human diseases, including diabetes and Parkinson's disease.
However, the alpha-Tocopherol quinone did not kill cells, nor did it interfere with protein folding. The researchers repeated their experiments on kidney cells cultured from monkeys and on skin cells cultured from mice and found similar results.
" We think that gamma-Tocopherol may have this kind of damaging effect on nearly every type of cell in the body," Ma said.
