Glucocorticoid-induced model of insulin resistance

Explore our rapid model of glucocorticoid-induced insulin resistance, ideal for testing antidiabetic potential of new drugs. Witness the inhibitory effects of mifepristone and CORT125134 on insulin resistance and hyperglycaemia in rats.

Glucocorticoid-induced model of insulin resistance

We have developed a rapid model of insulin resistance induced by sub-chronic administration of the glucocorticoid, cortisone, resulting in significantly increased plasma glucose and insulinΒ levelsΒ within 7 days in rats. This model can be used to evaluate the antidiabetic potential of novel drugs such as selective glucocorticoid receptor antagonists, or inhibitors of 11Ξ² hydroxysteroid dehydrogenase (11Ξ²HSD). These enzymes catalyse the conversion of cortisone to cortisol (andΒ vice versa), and therefore regulate the access of glucocorticoids to steroid receptors. Below is an example demonstrating inhibition of the phenotype by mifepristone and the glucocorticoid receptor antagonist CORT125134.

The glucocorticoid receptor antagonists CORT125134 and mifepristone improve cortisone-induced insulin resistance and hyperglycaemia in male Sprague Dawley rats
