MetabolomicsMetabolic profilings of rat INS-1 β-cells under changing levels of essential amino acids

Application of mass spectrometry enables the detection of metabolic differences between organisms with different nutritional settings. Divergence in the metabolic fingerprints of rat pancreatic INS-1 β-cells were systematically captured with regard to 10 individual essential amino acid (EAA) avai...

MetabolomicsIAPP toxicity activates HIF1α/PFKFB3 signaling delaying β-cell loss at the expense of β-cell function
The islet in type 2 diabetes (T2D) is characterized by amyloid deposits derived from islet amyloid polypeptide (IAPP), a protein co-expressed with insulin by β-cells. In common with amyloidogenic proteins implicated in neurodegeneration, human IAPP (hIAPP) forms membrane permeant toxic oligomers imp...

MetabolomicsTGF-β uncouples glycolysis and inflammation in macrophages and controls the survival during sepsis

The mechanisms by which macrophage metabolism is regulated and the effects of metabolism on diseases remain largely unknown. We show here that TGF-β regulates the glycolysis of macrophages independently of inflammatory cytokine production, and thus affects the survival in experimental sepsis. Spe...

MetabolomicsUsing an NMR metabolomics approach to investigate the pathogenicity of amyloid-beta and alpha-synuclein
INTRODUCTION: The pathogenicity at differing points along the aggregation pathway of many fibril-forming proteins associated with neurodegenerative diseases is unclear. Understanding the effect of different aggregation states of these proteins on cellular processes is essential to enhance understand...

MetabolomicsMetabolic characterization of directly reprogrammed renal tubular epithelial cells (iRECs)
Fibroblasts can be directly reprogrammed to induced renal tubular epithelial cells (iRECs) using four transcription factors. These engineered cells may be used for disease modeling, cell replacement therapy or drug and toxicity testing. Direct reprogramming induces drastic changes in the transcripti...

MetabolomicsAMPK activation induces RALDH+ tolerogenic dendritic cells by rewiring glucose and lipid metabolism.
Dendritic cell (DC) activation and function are underpinned by profound changes in cellular metabolism. Several studies indicate that the ability of DCs to promote tolerance is dependent on catabolic metabolism. Yet the contribution of AMP-activated kinase (AMPK), a central energy sensor promoting c...

MetabolomicsMesenchymal stromal cells secretome restores bioenergetic and redox homeostasis in human proximal tubule cells after ischemic injury

BACKGROUND: Ischemia/reperfusion injury (IRI) is the leading cause of acute kidney injury (AKI). The current standard of care focuses on supporting kidney function, stating the need for more efficient and targeted therapies to enhance repair. Mesenchymal Stromal Cells (MSCs) and ...

MetabolomicsGABA regulates IL-1β production in macrophages
Neurotransmitters have been well-documented to determine immune cell fates; however, whether and how γ-amino butyric acid (GABA) shapes the function of innate immune cells is still obscure. Here, we demonstrated that GABA orchestrates macrophage maturation and inflammation. GABA treatment during mac...
