Dysregulation of glucocorticoid metabolism in murine obesity: comparable effects of leptin resistance and deficiency

In obese humans, metabolism of glucocorticoids by 11 beta-hydroxysteroid dehydrogenase type 1 (11 beta-HSD1) and A-ring reduction (by 5 alpha- and 5 beta-reductases) is dysregulated in a tissue specific manner. These changes have been recapitulated in leptin resistant obese Zucker rats but were not observed in high-fat fed Wistar rats. Recent data from… CONTINUE READING
