An integrative multi-omics approach reveals new central nervous system pathway alterations in Alzheimer's disease

Background Multiple pathophysiological processes have been described in Alzheimer's disease (AD). Their inter-individual variations, complex interrelations, and relevance for clinical manifestation and disease progression remain poorly understood. We hypot ...

Discovery and validation of temporal patterns involved in human brain ketometabolism in cerebral microdialysis fluids of traumatic brain injury patients

Sarah Catherine Sonnay, Anirikh Chakrabarti, Nicolas Christinat, Mojgan Masoodi

Background: Traumatic brain injury (TBI) is recognized as a metabolic disease, characterized by acute cerebral glucose hypo-metabolism. Adaptive metabolic responses to TBI involve the utilization of alternative energy substrates, such as ketone bodies. Cer ...

Nutritional Ketosis Increases NAD+/NADH Ratio in Healthy Human Brain: An in Vivo Study by 31P-MRS

Rolf Gruetter, Lijing Xin, Özlem Ipek, Mojgan Masoodi, Nicolas Christinat, Maya Shevlyakova

Ketones represent an important alternative fuel for the brain under glucose hypo-metabolic conditions induced by neurological diseases or aging, however their metabolic consequences in healthy brains remain unclear. Here we report that ketones can increase ...

Aging and sarcopenia associate with specific interactions between gut microbes, serum biomarkers and host physiology in rats

Sonia Karaz, Anirikh Chakrabarti, Mojgan Masoodi, Alice Pannerec, Jay Siddharth

The microbiome has been demonstrated to play an integral role in the maintenance of many aspects of health that are also associated with aging. In order to identify areas of potential exploration and intervention, we simultaneously characterized age-relate ...

Perturbed rhythmic activation of signaling pathways in mice deficient for Sterol Carrier Protein 2-dependent diurnal lipid transport and metabolism

Cédric Gobet, Sylviane Métairon, Frédéric Bruno Martin Gachon, Mojgan Masoodi, Celine Jouffe

Through evolution, most of the living species have acquired a time keeping system to anticipate daily changes caused by the rotation of the Earth. In all of the systems this pacemaker is based on a molecular transcriptional/translational negative feedback ...

Imaging the time-integrated cerebral metabolic activity with subcellular resolution through nanometer-scale detection of biosynthetic products deriving from (13)C-glucose

Anders Meibom, Graham Knott, Arnaud Comment, Stéphane Laurent Escrig, Yuhei Takado, Mojgan Masoodi

Glucose is the primary source of energy for the brain but also an important source of building blocks for proteins, lipids, and nucleic acids. Little is known about the use of glucose for biosynthesis in tissues at the cellular level. We demonstrate that l ...

Imaging liver and brain glycogen metabolism at the nanometer scale

Anders Meibom, Graham Knott, Arnaud Comment, Stéphane Laurent Escrig, Yuhei Takado, Mojgan Masoodi

In mammals, glycogen synthesis and degradation are dynamic processes regulating blood and cerebral glucose-levels within a well-defined physiological range. Despite the essential role of glycogen in hepatic and cerebral metabolism, its spatiotemporal distr ...
