Novel compartment-specific biosensors reveal a complementary subcellular distribution of bioactive Furin and PC7

Pierpaolo Ginefra

Proprotein Convertases (PCs) constitute a family of serine proteases that activate various hormones, growth factors and cell adhesion molecules by mediating endoproteolytic cleavage of their secreted inactive precursors during their transit in the secret ...

A multiscale study of the role of dynamin in the regulation of glucose uptake

Johan Auwerx, Martinus Gijs, Kristina Schoonjans, Laurent Mouchiroud, Raphaël Etienne Jean Trouillon, Keir Joe Menzies, Maria Cristina Letizia

Glucose uptake in muscle cells in response to insulin is a fundamental mechanism for metabolism. The inability of cells to mobilize the specific glucose transporter GLUT4 is believed to be at least partially accountable for diseases, like diabetes, where c ...

Growth differentiation factor 15 is a myomitokine governing systemic energy homeostasis

Johan Auwerx, Dongryeol Ryu

Reduced mitochondria! electron transport chain activity promotes longevity and improves energy homeostasis via cell-autonomous and non-autonomous factors in multiple model systems. This mitohormetic effect is thought to involve the mitochondrial unfolded p ...

A systems perspective on brown adipogenesis and metabolic activation

Bart Deplancke, Magda Zachara, Rachana Narendra Pradhan

Brown adipocytes regulate energy expenditure via mitochondrial uncoupling. This makes these fat cells attractive therapeutic targets to tackle the burgeoning issue of obesity, which itself is coupled to insulin resistance, type 2 diabetes, cardiovascular a ...

The NAD(+)-dependent deacetylase SIRT2 attenuates oxidative stress and mitochondrial dysfunction and improves insulin sensitivity in hepatocytes

Vera Monica Lemos Da Silva

Insulin resistance is a major predictor of the development of metabolic disorders. Sirtuins (SIRTs) have emerged as potential targets that can be manipulated to counteract age-related diseases, including type 2 diabetes. SIRT2 has been recently shown to ex ...

Multipotent mesenchymal stromal cells enhance insulin secretion from human islets via N-Cadherin interaction and prolong function of transplanted encapsulated islets in mice

Sandrine Gerber, Jutta Christine Wandrey, Redouan Mahou

Background: Multipotent mesenchymal stromal cells (MSC) enhance viability and function of islets of Langerhans. We aimed to examine the interactions between human MSC and human islets of Langerhans that influence the function of islets. Methods: Human MSC ...

SIRT1 Gain of Function Does Not Mimic or Enhance the Adaptations to Intermittent Fasting

Carlos Canto Alvarez, Patrick Descombes, Sylviane Métairon

Caloric restriction (CR) has been shown to prevent the onset of insulin resistance and to delay age-related physiological decline in mammalian organisms. SIRT1, a NAD(+) -dependent deacetylase enzyme, has been suggested to mediate the adaptive responses to ...

Dietary restriction and Sirtuin 1 in metabolic health: connections and divergences

Carlos Canto Alvarez

Aging is the major risk factor for a constellation of multifactorial diseases, including insulin resistance, diabetes and cardiovascular complications. Dietary restriction has been shown to delay or prevent the manifestation of age-related health decline, ...

Mfn1 Deficiency in the Liver Protects Against Diet-Induced Insulin Resistance and Enhances the Hypoglycemic Effect of Metformin

Carlos Canto Alvarez, Catherine Maclachlan, Patrick Descombes, Sylviane Métairon, Richardus Houtkooper, Joanna Ratajczak, Wen Gao

Mitochondrial function can be influenced by mitochondrial shape and connectivity with other cellular organelles through fusion and fission processes. Disturbances in mitochondrial architecture and mitochondrial fusion related genes are observed in situatio ...
