MetabolomicsCommon Metabolic Pathways Implicated in Resistance to Chemotherapy Point to a Key Mitochondrial Role in Breast Cancer
Cancer cells are known to reprogram their metabolism to adapt to adverse conditions dictated by tumor growth and microenvironment. A subtype of cancer cells with stem-like properties, known as cancer stem cells (CSC), is thought to be responsible for tumor recurrence. In this study, we demonstrated ...

ProteomicsDisruption of mitochondrial dynamics triggers muscle inflammation through interorganellar contacts and mtDNA mislocation
Some forms of mitochondrial dysfunction induce sterile inflammation through mitochondrial DNA (mtDNA) recognition by intracellular DNA sensors. However, the involvement of mitochondrial dynamics mitigating such processes and their impact on muscle fitness remain unaddressed. Here we report that oppo...

TranscriptomicsMitofusin 2 expression in muscle decreases during aging and generates a gene signature characteristic of aged muscle
Mitochondrial fusion and fission proteins regulate mitochondrial quality control and mitochondrial metabolism. In turn, mitochondrial dysfunction is associated with aging, although its causes are still under debate. Here, we show that aging is characterized by a progressive reduction of Mitofusin 2 ...

TranscriptomicsMus musculus gene expression profiling for Wt, SKM-Tg, C and SKM-KO in Affymetrix 430PM strip arrays
We analyzed the functional role of DOR (Diabetes and Obesity Regulated gene) (also named Tp53inp2) in skeletal muscle. We show that DOR has a direct impact on skeletal muscle mass in vivo. Thus, using different transgenic mouse models, we demonstrate that while muscle-specific DOR gain-of-function r...

MetabolomicsDeficient Endoplasmic Reticulum-Mitochondrial Phosphatidylserine Transfer Causes Liver Disease
Non-alcoholic fatty liver is the most common liver disease worldwide. Here, we show that the mitochondrial protein mitofusin 2 (Mfn2) protects against liver disease. Reduced Mfn2 expression was detected in liver biopsies from patients with non-alcoholic steatohepatitis (NASH). Moreover, reduced Mfn2...

TranscriptomicsReduced a-MSH underlies hypothalamic endoplasmic reticulum stress-induced hepatic gluconeogenesis
Alterations in endoplasmic reticulum (ER) homeostasis have been implicated in the pathophysiology of obesity and type-2 diabetes (T2D). Acute ER stress induction in the hypothalamus produces glucose metabolism perturbations. However, the neurobiological basis linking hypothalamic ER stress with abno...

TranscriptomicsRNA-seq of mouse astrocytes in monoculture and co-cultured with rat neurons (both inactive and active).
Neurons induce a dramatic transformation in developing astrocytes, causing them to develop a complex stellate morphology resembling their appearance in vivo. However, the transcriptional changes that accompany this transformation are not known, nor are the signalling mechanisms responsible. Similarl...
