Amino Acid Neurotransmission and its Regulation by Valproate: Focus on Aspartate

open access: yes, 2012
Synaptic transmission requires packing of neurotransmitters into synaptic vesicles. The role of aspartate as a neurotransmitter has been debated for more than 30 years, as vesicular accumulation of aspartate has been difficult to prove.

(Biotechnology Progress,25(6):1637-1642)Asymmetrically simultaneous synthesis of L-Homophenylalanine and N6-Protected-2-oxo-6-amino-hexanoic acid by engineered Escherichia coli aspartate aminotransferase

open access: yes, 2014
L-Homophenylalanine (L-HPA) and N-6-protected-2-oxo-6-amino-hexanoic acid (N-6-protected-OAHA) an be used as building blocks for the manufacture of angiotensin-converting enzyme inhibitors. To synthesize L-HPA and N-6-protected-OAHA simultaneously from 2-

Dual‐Functional Ingestible Passive Capsules for High‐Throughput Intestinal Sampling with Sealed Containment and Targeted Drug Delivery

open access: yesAdvanced Robotics Research, EarlyView.
To address challenges in high‐throughput intestinal sampling with sealed containment and target drug delivery, we developed a dual‐functional ingestible passive capsule with a dual‐triggered control system based on pH‐response and mechanical actuation.

Potassium channel activators protect the N-methyl-D-aspartate-induced cerebral vascular dilation after combined hypoxia and ischemia in piglets

open access: yes, 1998
Background and Purpose-Cerebral arteriolar dilation to N-methyl-D-aspartate (NMDA) is a neuronally mediated multistep process that is sensitive to cerebral hypoxia and ischemia (H/I).

Central Role of Glutamate Metabolism in the Maintenance of Nitrogen Homeostasis in Normal and Hyperammonemic Brain

open access: yesBiomolecules, 2016
Glutamate is present in the brain at an average concentration—typically 10–12 mM—far in excess of those of other amino acids. In glutamate-containing vesicles in the brain, the concentration of glutamate may even exceed 100 mM. Yet because glutamate is a

Engineered Mesenchymal Stem Cell–NK Cell Complexes for Spatially Targeted and Functionally Revitalized Cancer Immunotherapy

open access: yesAdvanced Science, EarlyView.
IL‐15‐engineered stem cell–NK cell complexes, assembled via bioorthogonal chemistry, enable effective lung cancer immunotherapy. Abstract Natural killer (NK) cells represent a powerful immunotherapeutic strategy due to their intrinsic cytotoxicity and ability to target tumor cells independently of antigen presentation.

Crosstalk Between Brain-Derived Neurotrophic Factor And N-Methyl-D-Aspartate Receptor Signaling In Neurons

open access: yes, 2008
Glutamate is the major excitatory neurotransmitter in brain exerting prosurvival effect on neurons via N-methyl-D-aspartate receptor (NMDAR) signaling under physiological conditions.

Characterization of Three L-Asparaginases from Maritime Pine (Pinus pinaster Ait.)

open access: yesFrontiers in Plant Science, 2017
Asparaginases (ASPG, EC 3.5.1.1) catalyze the hydrolysis of the amide group of L-asparagine producing L-aspartate and ammonium. Three ASPG, PpASPG1, PpASPG2, and PpASPG3, have been identified in the transcriptome of maritime pine (Pinus pinaster Ait ...

LC3B Mediated SETDB1‐Accounted Alcoholic Steatohepatitis via Lipidation‐Dependent LAP and Lipidation‐Independent Nuclear Stabilization

open access: yesAdvanced Science, EarlyView.
SETDB1 is progressively downregulated in ALD, correlating with disease severity. SETDB1 deficiency impairs LAP by disrupting Rubicon membrane localization, leading to defective lipid droplet clearance. Concurrently, loss of SETDB1 reduces nuclear LC3B, causing R‐loop accumulation and cGAS‐STING‐driven inflammation. Lipidated LC3B mediates LAP‐dependent

Paternal Circadian Disruption Impairs Offspring Cognition via Sperm microRNAs

open access: yesAdvanced Science, EarlyView.
Paternal circadian disruption remodels the sperm small RNA payload, elevating miR‐92a‐3p/miR‐25‐3p levels and perturbing early embryonic gene regulatory programs. Microinjection experiments and single‐embryo transcriptomics reveal sex‐specific developmental vulnerabilities, ultimately impairing offspring hippocampal synaptic plasticity and cognition ...
