SIRT7 modulates the stability and activity of the renal K-Cl cotransporter KCC4 through deacetylation

Olivier Staub, Johan Auwerx, Lilia Noriega Lopez, Dongryeol Ryu

SIRT7 is a NAD(+)-dependent deacetylase that controls important aspects of metabolism, cancer, and bone formation. However, the molecular targets and functions of SIRT7 in the kidney are currently unknown. In silico analysis of kidney transcripts of the BX ...

Genistein increases the thermogenic program of subcutaneous WAT and increases energy expenditure in mice

Lilia Noriega Lopez, Laura Alejandra Velazquez Villegas

White adipose tissue (WAT) can differentiate into beige adipose tissue by the browning process. Some polyphenols, including isoflavones, particularly genistein, are suggested to increase the expression of browning markers. There is evidence that consumptio ...

Metabolic Characterization of a Sirt5 deficient mouse model

Kristina Schoonjans, Johan Auwerx, Lilia Noriega Lopez, Jiujiu Yu, Norman Lionel Moullan

Sirt5, localized in the mitochondria, is a member of sirtuin family of NAD(+)-dependent deacetylases. Sirt5 was shown to deacetylate and activate carbamoyl phosphate synthase 1. Most recently, Sirt5 was reported to be the predominant protein desuccinylase ...

The bile acid membrane receptor TGR5 as an emerging target in metabolism and inflammation

Kristina Schoonjans, Johan Auwerx, Lilia Noriega Lopez, Mitsunori Nomura, Thijs Pols

Bile acids (BAs) are amphipathic molecules that facilitate the uptake of lipids, and their levels fluctuate in the intestine as well as in the blood circulation depending on food intake. Besides their role in dietary lipid absorption, bile acids function a ...

CREB and ChREBP oppositely regulate SIRT1 expression in response to energy availability

Johan Auwerx, Lilia Noriega Lopez, Jiujiu Yu, Carlos Canto Alvarez, Chikage Mataki, Hiroyasu Yamamoto

The nicotinamide adenine dinucleotide (NAD(+))-dependent deacetylase SIRT1 is a major metabolic regulator activated by energy stresses such as fasting or calorie restriction. SIRT1 activation during fasting not only relies on the increase in the NAD(+)/NAD ...

The bile acid membrane receptor TGR5: a valuable metabolic target

Kristina Schoonjans, Johan Auwerx, Lilia Noriega Lopez, Mitsunori Nomura, Thijs Pols

Bile acids (BAs) are amphipathic molecules that facilitate the uptake of lipids, and their levels fluctuate in the intestines as well as in the circulation depending on food intake. Besides their role in dietary lipid absorption, BAs function as signaling ...

AMPK regulates energy expenditure by modulating NAD(+) metabolism and SIRT1 activity

Johan Auwerx, Lilia Noriega Lopez, Carlos Canto Alvarez

AMP-activated protein kinase (AMPK) is a metabolic fuel gauge conserved along the evolutionary scale in eukaryotes that senses changes in the intracellular AMP/ATP ratio. Recent evidence indicated an important role for AMPK in the therapeutic benefits of m ...
