Hepatic steatosis is caused by metabolic imbalances that could be explained in part by an increase in de novo lipogenesis that results from increased sterol element binding protein 1 (SREBP-1) activity. The nuclear receptor liver receptor homolog 1 (LRH-1) ...

Degradation of PHLPP2 by KCTD17, via a Glucagon-Dependent Pathway, Promotes Hepatic Steatosis

Johan Auwerx, Dongryeol Ryu

BACKGROUND & AIMS: Obesity-induced nonalcoholic fatty liver disease (NAFLD) develops, in part, via excess insulin-stimulated hepatic de novo lipogenesis, which increases, paradoxically, in patients with obesity-induced insulin resistance. Pleckstrin homolo ...

Abstract of the invention: The present invention relates to agents that induce mitochondrial unfolded protein response (UPR mt ) in muscle stem cells and prevents or reverse process of muscle stem cell senescence. Further, the invention relates to methods ...

Metabolomics-assisted proteomics identifies succinylation and SIRT5 as important regulators of cardiac function

Johan Auwerx, Zhi Li, Wei Chen, Dongryeol Ryu, Shuo Zhang

Cellular metabolites, such as acyl-CoA, can modify proteins, leading to protein posttranslational modifications (PTMs). One such PTM is lysine succinylation, which is regulated by sirtuin 5 (SIRT5). Although numerous proteins are modified by lysine succiny ...

Neuromuscular diseases are often caused by inherited mutations that lead to progressive skeletal muscle weakness and degeneration. In diverse populations of normal healthy mice, we observed correlations between the abundance of mRNA transcripts related to ...

Adult stem cells (SCs) are essential for tissue maintenance and regeneration yet are susceptible to senescence during aging. We demonstrate the importance of the amount of the oxidized form of cellular nicotinamide adenine dinucleotide (NAD(+)) and its imp ...

The biological effects of urolithins remain poorly characterized, despite wide-spread human exposure via the dietary consumption of their metabolic precursors, the ellagitannins, which are found in the pomegranate fruit, as well as in nuts and berries. We ...

LRH-1-dependent programming of mitochondrial glutamine processing drives liver cancer

Johan Auwerx, Kristina Schoonjans, Hadrien Charles Edouard Demagny, Arnaud Comment, Dongryeol Ryu, Xu Wang, Norman Lionel Moullan, Emine Can, Matthias Alexander Sokrates Stein, Maaike Hélène Oosterveer, Pan Xu

Various tumors develop addiction to glutamine to support uncontrolled cell proliferation. Here we identify the nuclear receptor liver receptor homolog 1 (LRH-1) as a key regulator in the process of hepatic tumorigenesis through the coordination of a noncan ...
