MetabolomicsLysosome Lipid Signaling from the Periphery to Neurons Regulates Longevity

Lysosomes are key cellular organelles that metabolize extra- and intra-cellular substrates. Alterations in lysosomal metabolism are implicated in aging-associated metabolic and neurodegenerative diseases. However, how lysosomal metabolism actively coordinates the metabolic and nervous systems to ...

MetabolomicsHuman umbilical cord-derived mesenchymal stem cells ameliorate perioperative neurocognitive disorder by inhibiting inflammatory responses and activating BDNF/TrkB/CREB signaling pathway in aged mice

BACKGROUND: Perioperative neurocognitive disorder (PND) is a key complication affecting older individuals after anesthesia and surgery. Failure to translate multiple pharmacological therapies for PND from preclinical studies to clinical settings has necessitated the exploration o...

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...

TranscriptomicsDistinct roles for Toll and autophagy pathways in double-stranded RNA toxicity in a Drosophila model of expanded repeat neurodegenerative diseases
Dominantly inherited expanded repeat neurodegenerative diseases are typically caused by the expansion of existing variable copy number tandem repeat sequences in otherwise unrelated genes. Repeats located in translated regions encode polyglutamine that is thought to be the toxic agent, however in se...

ProteomicsSkeletal Muscle TFEB Signaling Promotes Central Nervous System Function and Reduces Neuroinflammation during Aging and Neurodegenerative Disease
Skeletal muscle has recently arisen as a novel regulator of Central Nervous System (CNS) function and aging, secreting bioactive molecules known as myokines with metabolism-modifying functions in targeted tissues, including the CNS. Here we report the generation of a novel transgenic mouse with enha...

ProteomicsDefining the dynamic regulation of O-GlcNAc proteome in the mouse cortex -- The O-GlcNAcylation of synaptic and trafficking proteins related to neurodegenerative diseases
Mice were i.p. injected Thiamet G (TG) or saline, and mouse brain cortex tissues were analyzed for O-GlcNAc by LC-MS/MS with TMT based quantification. Data was searched with MS-GF+ using PNNL's DMS processing pipeline.

TranscriptomicsHypothalamic gene expression profile indicates a reduction in G-protein signaling in the wfs1 mutant mice
WFS1 gene is coding protein with unknown function but its functional deficiency causes different neuropsychiatric and neuroendocrine syndromes. In the present study we aimed to find the functional networks influenced by the Wfs1 deficiency in the hypothalamus. We performed gene expression profiling ...

TranscriptomicsCycad Genotoxin Methylazoxymethanol (MAM) Modulates Cellular Pathways Involved in Cancer and Neurodegenerative Disease
Methylazoxymethanol (MAM), the genotoxic metabolite of the cycad azoxyglucoside cycasin, induces genetic alterations in bacteria, yeast, plants, insects and mammalian cells, but adult nerve cells are thought to be unaffected. We show that the brains of young adult mice treated with a single systemic...

TranscriptomicsExpression data from 2-3 month old brain-specific I?B? conditional knockout mice
The activation of NFkB pathway is commonly observed in many neurodegenerative disease and contributes to the disease pathogenesis. However, with hundreds of target genes expressed in the brain, the mechanism of NFkB signaling transduction pathway is bearly understood. We were interested in revealing...
