Asperuloside Improves Obesity and Type 2 Diabetes through Modulation of Gut Microbiota and Metabolic Signaling

Johan Auwerx, Qi Zhu

Asperuloside (ASP) is an iridoid glycoside that is extracted from Eucommia leaves. Eucommia is used in traditional Chinese medicine and has a long history of benefits on health and longevity. Here, we investigated the impact of ASP on obesity-related metab ...

Growth differentiation factor 15 protects against the aging-mediated systemic inflammatory response in humans and mice

Johan Auwerx, Jun Yong Kim, Ludger Jan Elzuë Goeminne, Dongryeol Ryu

Mitochondrial dysfunction is associated with aging-mediated inflammatory responses, leading to metabolic deterioration, development of insulin resistance, and type 2 diabetes. Growth differentiation factor 15 (GDF15) is an important mitokine generated in r ...

NAD(+) homeostasis in health and disease

Johan Auwerx, Mario Romani, Elena Katsyuba, Dina Hofer

The conceptual evolution of nicotinamide adenine dinucleotide (NAD(+)) from being seen as a simple metabolic cofactor to a pivotal cosubstrate for proteins regulating metabolism and longevity, including the sirtuin family of protein deacylases, has led to ...

Skeletal muscle enhancer interactions identify genes controlling whole-body metabolism

Johan Auwerx, Martin Rainer Wohlwend

Obesity and type 2 diabetes (T2D) are metabolic disorders influenced by lifestyle and genetic factors that are characterized by insulin resistance in skeletal muscle, a prominent site of glucose disposal. Numerous genetic variants have been associated with ...

NovelT2Mapping for Evaluating Cervical Cancer Features by Providing QuantitativeT2Maps and Synthetic Morphologic Images: A Preliminary Study

Tobias Kober, Tom Hilbert, Yong Zhang, Meng Yang, Jie Liu

Background The application value of T(2)mapping in evaluating cervical cancer (CC) features remains unclear. Purpose To investigate the role of T(2)values in evaluating CC classification, grade, and lymphovascular space invasion (LVSI) in comparison to app ...

Synchronous nonmonotonic changes in functional connectivity and white matter integrity in a rat model of sporadic Alzheimer's disease

Bernard Lanz, Katarzyna Pierzchala, Ileana Ozana Jelescu, Carole Poitry-Yamate, Ting Yin, Yujian Diao

Brain glucose hypometabolism has been singled out as an important contributor and possibly main trigger to Alzheimer's disease (AD). Intracerebroventricular injections of streptozotocin (icv-STZ) cause brain glucose hypometabolism without systemic diabetes ...

Combined deletion of Glut1 and Glut3 impairs lung adenocarcinoma growth

Rolf Gruetter, Anders Meibom, Graham Knott, Bernard Lanz, Stéphane Laurent Escrig, Nadine Fournier, Mario Gaetano Lepore, Etienne Meylan, Louise Helene Soegaard Jensen, Caroline Anne-Lyse Contat

Glucose utilization increases in tumors, a metabolic process that is observed clinically by F-18-fluorodeoxyglucose positron emission tomography (F-18-FDG-PET). However, is increased glucose uptake important for tumor cells, and which transporters are impl ...

Surface functionalization of metal oxide harmonic nanoparticles for targeted cancer imaging

Raphaël Jovita De Matos

Cancer is a major health burden worldwide and the leading cause of death in industrialized countries. Early detection is a primary factor of survival and remission rate. Classical imaging methods such as magnetic resonance imaging, ultrasound imaging and m ...

Metabolic plasticity and glucose transporter redundancy dictate lung adenocarcinoma growth

Caroline Anne-Lyse Contat

Lung cancers represent the leading cause of cancer-related deaths worldwide. These pulmonary cancers count several histological subgroups, whose non-small cell lung cancers, subject of our study. We were precisely interested in the most common subtype of n ...

Role of metabolism and mitochondria during glucose sensing and glucose-induced dysfunction in human pancreatic beta-cells

Isabelle Chareyron

Glucose sensing and regulation of insulin secretion are the two main functions performed by the pancreatic beta-cell. Together these processes contribute to the tight control of blood glucose in our body. Compromising the ability of the beta-cells to prope ...
