Lipopolysaccharide induces intestinal glucocorticoid synthesis in a TNFalpha-dependent manner

Stringent control of immune responses in the intestinal mucosa is critical for the maintenance of immune homeostasis and prevention of tissue damage, such as observed during inflammatory bowel disease. Intestinal epithelial cells, primarily thought to form ...

The nuclear cofactor DOR regulates autophagy in mammalian and Drosophila cells

Jordi Duran

The regulation of autophagy in metazoans is only partly understood, and there is a need to identify the proteins that control this process. The diabetes- and obesity-regulated gene (DOR), a recently reported nuclear cofactor of thyroid hormone receptors, i ...

Ppargamma2 is a key driver of longevity in the mouse

Johan Auwerx

Aging involves a progressive physiological remodeling that is controlled by both genetic and environmental factors. Many of these factors impact also on white adipose tissue (WAT), which has been shown to be a determinant of lifespan. Interrogating a trans ...

Adipose-specific knockout of raptor results in lean mice with enhanced mitochondrial respiration

Johan Auwerx

raptor is a specific and essential component of mammalian TOR complex 1 (mTORC1), a key regulator of cell growth and metabolism. To investigate a role of adipose mTORC1 in regulation of adipose and whole-body metabolism, we generated mice with an adipose-s ...

Mature-onset obesity and insulin resistance in mice deficient in the signaling adapter p62

Johan Auwerx

Signaling cascades that control adipogenesis are essential in the regulation of body weight and obesity. The adaptor p62 controls pathways that modulate cell differentiation. We report here that p62(-/-) mice develop mature-onset obesity, leptin resistance ...

Regulation of glucagon secretion by glucose transporter type 2 (glut2) and astrocyte-dependent glucose sensors

Friedrich Beermann

Ripglut1;glut2-/- mice have no endogenous glucose transporter type 2 (glut2) gene expression but rescue glucose-regulated insulin secretion. Control of glucagon plasma levels is, however, abnormal, with fed hyperglucagonemia and insensitivity to physiologi ...

Peroxisome proliferator-activated receptor gamma: the more the merrier?

Johan Auwerx

The consequence of activating the nuclear hormone receptor, peroxisome proliferator-activated receptor gamma (PPARgamma), which coordinates adipocyte differentiation, validates the concept, 'you are what you eat'. Excessive caloric intake leads to fat form ...

Leptin: cutting the fat off the bone

Johan Auwerx

CONTEXT: Leptin was initially proposed to be the antiobesity hormone. Now it is realised that leptin is more a signal molecule that communicates nutritional status to the brain, and that it is involved in bone formation by having an antiosteogenic action. ...

Activation of peroxisome proliferator-activated receptor delta induces fatty acid beta-oxidation in skeletal muscle and attenuates metabolic syndrome

Johan Auwerx

In this study, we defined the role of peroxisome proliferator-activated receptor beta/delta (PPARdelta) in metabolic homeostasis by using subtype selective agonists. Analysis of rat L6 myotubes treated with the PPARdelta subtype-selective agonist, GW501516 ...

PPAR(gamma) and glucose homeostasis

Johan Auwerx

Peroxisome proliferator-activated receptor gamma (PPARgamma) is a nuclear receptor involved in the control of metabolism. Research on PPARgamma is oriented towards understanding its role in insulin sensitization, which was inspired by the discovery that an ...
