Missing link between fructose, insulin resistance found
| |
A new study in mice sheds light on the insulin resistance that can come from diets loaded with high-fructose corn syrup, a sweetener found in most sodas and many other processed foods.
The report in the March issue of Cell Metabolism, a Cell Press publication, also suggests a way to prevent those ill effects.
The researchers showed that mice on a high-fructose diet were protected from insulin resistance when a gene known as transcriptional coactivator PPARg coactivator-1b (PGC-1b) was "knocked down" in the animals' liver and fat tissue. PGC-1b coactivates a number of transcription factors that control the activity of other genes, including one responsible for building fat in the liver.
"There has been a remarkable increase in consumption of high-fructose corn syrup," said Gerald Shulman of Yale University School of Medicine. "Fructose is...jasper
