Sensing of nutrients by CPT1C regulates late endosome/lysosome anterograde transport and axon growth
(eLife Sciences Publications, 2019)
Anterograde transport of late endosomes or lysosomes (LE/Lys) is crucial for proper axon growth. However, the role of energetic nutrients has been poorly explored. Malonyl-CoA is a precursor of fatty ...
Mechanisms of CPT1C-Dependent AMPAR trafficking enhancement
(Frontiers Media, 2018-08-08)
In neurons, AMPA receptor (AMPAR) function depends essentially on their constituent
components: the ion channel forming subunits and ion channel associated proteins.
On the other hand, AMPAR trafficking ...
Sensing of nutrients by CPT1C controls SAC1 activity to regulate AMPA receptor trafficking
(Rockefeller University Press, 2020)
Carnitine palmitoyltransferase 1C (CPT1C) is a sensor of malonyl-CoA and is located in the ER of neurons. AMPA receptors (AMPARs) mediate fast excitatory neurotransmission in the brain and play a key ...
CPT1C promotes human mesenchymal stem cells survival under glucose deprivation through the modulation of autophagy
(Nature Research, 2018-05-03)
Human mesenchymal stem cells (hMSCs) are widely used in regenerative medicine. In some
applications, they must survive under low nutrient conditions engendered by avascularity. Strategies to
improve ...
The return of malonyl-CoA to the brain: cognition and other stories
(Elsevier, 2021-01)
Nutrients, hormones and the energy sensor AMP-activated protein kinase (AMPK) tightly regulate the intracel-lular levels of the metabolic intermediary malonyl-CoA, which is a precursor of fatty ...
Novel regulation of the synthesis of α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor subunit gluA1 by carnitine palmitoyltransferase 1C (CPT1C) in the hippocampus
(American Society for Biochemistry and Molecular Biology, 2015-10-16)
The regulation of AMPA-type receptor (AMPAR) abundance in the postsynaptic membrane is an important mechanism involved in learning and memory formation. Recent data suggest that one of the constituents ...
Nurr1 protein Is required for N-methyl-d-aspartic acid (NMDA) receptor-mediated neuronal survival
(Elsevier, 2012-03-30)
NMDA receptor (NMDAR) stimulation promotes neuronal survival during brain development. Cerebellar granule cells (CGCs) need NMDAR stimulation to survive and develop. These neurons differentiate and ...
Soluble oligomers of amyloid-β peptide disrupt Membrane trafficking of α-amino-3-hydroxy-5-methylisoxazole-4-propionic acid receptor contributing to early synapse dysfunction
(Elsevier, 2011-08-05)
β-Amyloid (Aβ), a peptide generated from the amyloid precursor protein, is widely believed to underlie the pathophysiology of Alzheimer disease (AD). Emerging evidences suggest that soluble Aβ oligomers ...
X-linked Inhibitor of Apoptosis Protein negatively regulates neuronal differentiation through interaction with cRAF and Trk
(Nature Research, 2013-08-09)
X-linked Inhibitor of apoptosis protein (XIAP) has been classically identified as a cell death regulator. Here,
we demonstrate a novel function of XIAP as a regulator of neurite outgrowth in neuronal ...
N-methyl-DD-aspartate blocks activation of JNK and mitochondrial apoptotic pathway induced by potassium deprivation in cerebellar granule cells
(Elsevier, 2006-03-10)
During the postnatal development of cerebellum, lack of excitatory innervation from the mossy fibers results in cerebellar granule cell (CGC) apoptosis during the migration of the cells toward the ...
