PPARapple agonism influences<br />

glucose homeostasis by<br />

increasing fatty acid flux from<br />

peripheral tissues to the liver<br />

thereby alleviating the fatty acid<br />

inhibition <strong>of</strong> glucose disposal in<br />

skeletal muscle, ameliorating<br />

insulin resistance<br />
