Development and characterization of high-affinity leptins and leptin antagonists

Shpilman M , Niv-Spector L , Katz M , Varol C , Solomon G , Elinav E , Gertler A

Leptin is a pleiotropic hormone acting both centrally and peripherally. It participates in variety of biological processes including energy metabolism, reproduction and modulation of the immune response. So far structural elements affecting leptin binding to its receptor remain unknown. We employed random mutagenesis of leptin, followed by selection of high-affinity mutants by yeast-surface display and discovered that replacing residue D23 with a non-negatively charged amino a...

TNFα plays an essential role in the downregulation of sex hormone-binding globulin production by decreasing hepatic HNF-4α through NF-κB activation

Barbosa-Desongles A , Simo R , Lecube A , Hernandez C , Selva D

The reason why obesity (a chronic low-grade inflammatory disease) is associated with low levels of sex hormone-binding globulin (SHBG) remains to be elucidated. In the present study we provide evidence that TNFα (a proinflammatory cytokine that increases with obesity) reduces SHBG production by human HepG2 hepatoblastoma cells. The effect of TNFα on human SHBG expression was mediated by NF-κB which causes the downregulation of HNF4α: a key SHBG transcriptio...

Benzofran derivatives inhibit 11β-hydroxysteroid dehydrogenase type 1 in rodent adipose tissue

Kobayashi Y , Daisuke K , Yamaguchi Y , Ueda M , Miyata O , Tagawa N

Excess glucocorticoids (GC) promote visceral obesity, hyperlipidemia and insulin resistance. The main regulators of intracellular GC levels are 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1), which converts inactive GC into bioactive forms such as cortisol in humans and corticosterone in rodents. Therefore, the inhibition of 11β-HSD1 has considerable therapeutic potential for metabolic diseases including obesity and diabetes. Benzofran is a key structure in ...

Effect of dehydroepiandrosterone on 11β-hydroxysteroid dehydrogenase type 1 in rodent adipocytes

Tagawa N , Minamitani E , Kiyonaga D , Kobayashi Y

Dehydroepiandrosterone (DHEA) has been suggested to have an anti-obesity effect; however, the mechanism underlying this effect remains unclear. The effect of DHEA on adipocytes opposes that of glucocorticoids, which potentiate adipogenesis. The key to the intracellular activation of glucocorticoids in adipocytes is 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1), which catalyses the production of active glucocorticoids (cortisol in humans and corticosterone in rod...

The loss of myostatin by gene disruption prevents an age-related increase in adipose tissue mass and partially attenuates the obese and diabetic phenotypes.
