According To Research
The potential health benefits
of
resveratrol may be due to is ability
to activate the powerful fat controlling
hormone adiponectin, according to an
important new study.
Researchers from the
University of Texas found that the antioxidant
compound resveratrol stimulates the expression of adiponectin,
a hormone released from fat cells, which plays an important
role in the regulation of insulin sensitivityand energy.
The new study, published in
the Journal of Biological Chemistry,
reports that resveratrol stimulates the expression and protein
clustering (multi-merization) of adiponectin in specialized fat
cells through the activation of a protein known as disulfide
bond-A oxidoreductase- like protein (DsbA-L).
"Our study uncovers a novel
mechanism by which resveratrol
exerts its health beneficial effect," said pharmacology
researchers at University of Texas.
"The results from these
studies should be of interest to those
who are obese, diabetic and growing older," he added.
They said the finding that
resveratrol promotes adiponectin
expression provides a novel mechanism by which resveratrol
exerts its health beneficial functions.
Resveratrol, a powerful
polyphenol and anti-fungal chemical,
is regarded as the major bioactive compound in grapes, grape
seeds and red wine. It has long been associated with the
so-called "French Paradox" which describes the low incidence
of heart disease and obesity among the French, despite their
relatively high-fat diet and levels of wine consumption.
Interest in the compound
exploded in 2003 when research
from from Harvard reported that resveratrol was able to
increase the lifespan of yeast cells. The research, published
in Nature, was greeted with international media attention and
stimulated hope worldwide for an effective anti-aging pill.
According to the Harvard
study's findings, resveratrol
activated a gene called sirtuin1 (Sirt1), which is also activated
during calorie restriction in various species, including humans.
However, recent studies have
suggested that resveratrol
may exert its beneficial functions via Sirt1-independent
mechanisms.
Adiponectin has a wide range
of beneficial effects on obesity-
related medical complications, and noted that both adiponectin
and resveratrol display anti-obesity, anti-insulin resistance and
anti-aging
properties.
Whilst recent research has
identified that the expression
DsbA-L, a protein that is known to regulate the expression
of adiponectin, is significantly reduced in obese human
subjects and mice.
