MetabolomicsMultiomics of synaptic junctions reveals altered lipid metabolism and signaling following environmental enrichment
Membrane lipids and their metabolism have key functions in neurotransmission. Here we provide a quantitative lipid inventory of mouse and rat synaptic junctions. To this end, we developed a multiomics extraction and analysis workflow to probe the interplay of proteins and lipids in synaptic signal t...

MetabolomicsEssential omega-3 fatty acids tune microglial phagocytosis of synaptic elements in the developing brain

Omega-3 fatty acids (n-3 polyunsaturated fatty acids; n-3 PUFAs) are essential for the functional maturation of the brain. Westernization of dietary habits in both developed and developing countries is accompanied by a progressive reduction in dietary intake of n-3 PUFAs. Low maternal intake of n...

MetabolomicsA thioredoxin-Serinc2-lipid signaling axis modulates mood-related behaviors in mice
Bipolar disorder (BD) shows strong heritability and distinct symptomatic subtypes. However, the molecular basis underlying subtype-specific features remains poorly understood. Here, we showed that Serinc2, a BD susceptibility gene encoding a L-serine transporter that regulates membrane lipid synthes...

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...

MetabolomicsMethionine cycle in C. elegans serotonergic neurons regulates diet-dependent behaviour and longevity through neuron-gut signaling

The folate and methionine cycles (Met-C) are regulated by vitamin B12 (B12), obtained exclusively from diet and microbiota. Met-C supports amino acid, nucleotide, and lipid biosynthesis and provides one-carbon moieties for methylation reactions. While B12 deficiency and polymorphisms in Met-C gen...

ProteomicsAltered GM1 catabolism affects NMDAR-mediated Ca2+ signaling at ER-PM junctions and increases synaptic spine formation
GM1-ganglioside, an abundant GSL in neuronal membranes, is integral to ER-PM junctions where it interacts with synaptic proteins/receptors and regulates Ca2+ signaling.

TranscriptomicsTranscription profiling of mouse skeletal muscle to detect genes that regulate motor axon growth and differentiation
These experiments are designed to discover genes that are expressed selectively by synaptic nuclei in skeletal muscle with the particular goal of identifying genes that regulate motor axon growth and differentiation. We plan to isolate RNA from the dissected synaptic region of skeletal muscle and fr...

ProteomicsMulti-omics reveals the lipid inventory of synaptic junctions and altered lipid signaling in environmental enrichment
Membrane lipids are essential components of synaptic junctions that have key functions in neurotransmission. In the first part of the study, we provide a quantitative lipid inventory of mouse and rat synaptic junctions. We next used a simultaneous multi-omics extraction and analysis workflow termed ...

TranscriptomicsSynaptic activity-regulated gene expression_embryonic day 16
Activity-dependent changes in synapses rely on functional changes in resident proteins and on gene expression. We addressed the relationship between synapse activity and the expression of synaptic genes by comparing RNA levels in the neocortex of normal mice versus synaptically silent munc18-1 null ...

MetabolomicsIntegrated proteomic and metabolomic profiling reveals molecular signatures underlying invasiveness in non-functioning pituitary adenomas

Pituitary adenomas constitute 10 to 25% of intracranial tumors, rendering them one of the most prevalent types of brain tumors. While the majority of pituitary adenomas are benign, ~35% exhibit invasive behavior. Compared with their non-invasive counterparts, invasive pituitary adenomas are more ...
