Research Progress of Amino Acid Metabolism PET Imaging in Tumor

Journal of Isotopes, 2015
Amino acid metabolism PET imaging plays a very important role in metabolism molecular imaging. Amino acid PET tracers include ［1-11C］amino acid, labeling α-C amino acid, labeling side-chain amino acid, and N-substituted labeling amino acid.

Integrated nontargeted and targeted metabolomics analyses amino acids metabolism in infantile hemangioma

Frontiers in Oncology, 2023
Infantile hemangioma (IH) is the most common benign tumor in children. However, the exact pathogenesis of IH remains unclear. Integrated nontargeted and targeted metabolic analyses were performed to obtain insight into the possible pathogenic mechanism ...

Connections Between Amino Acid Metabolisms in Plants: Lysine as an Example

Frontiers in Plant Science, 2020
Extensive efforts have been made to fortify essential amino acids and boost nutrition in plants, but unintended effects on growth and physiology are also observed.

Xenogeneic, extracorporeal liver perfusion in primates improves the ratio of branched-chain amino acids to aromatic amino acids (Fischer's ratio) [PDF]

, 1999
In fulminant hepatic failure (FHF), the development of hepatic encephalopathy is associated with grossly abnormal concentrations of plasma amino acids (PAA).

Determination of a steady-state isotope dilution protocol for carbon oxidation studies in the domestic cat

Journal of Nutritional Science, 2023
The present study aimed to develop an isotope protocol to achieve equilibrium of 13CO2 in breath of cats during carbon oxidation studies using L-[1-13C]-Phenylalanine (L-[1-13C]-Phe), provided orally in repeated meals.

Multi-Omics Data Reveal Amino Acids Related Genes in the Common Carp Cyprinus carpio

Fishes, 2022
Amino acids have important physiological effects on fish growth and development and are essential nutrition for humans. Flavor-related amino acids, such as glutamic acid and glycine, could have a significant effect on the taste of fish flesh.

Root phloem-specific expression of the plasma membrane amino acid proton co-transporter AAP3 [PDF]

, 2004
Amino acids are regarded as the nitrogen ‘currency’ of plants. Amino acids can be taken up from the soil directly or synthesized from inorganic nitrogen, and then circulated in the plant via phloem and xylem.

The catalytic subunit of the system L1 amino acid transporter (Slc7a5) facilitates nutrient signalling in mouse skeletal muscle [PDF]

, 2014
The System L1-type amino acid transporter mediates transport of large neutral amino acids (LNAA) in many mammalian cell-types. LNAA such as leucine are required for full activation of the mTOR-S6K signalling pathway promoting protein synthesis and cell ...

Metabolism of amino acid amides in Pseudomonas putida ATCC 12633 [PDF]

, 1993
The metabolism of the natural amino acid L-valine, the unnatural amino acids D-valine, and D-, L-phenylglycine (D-, L-PG), and the unnatural amino acid amides D-, L-phenylglycine amide (D, L-PG-NH2) and L-valine amide (L-Val-NH2) was studied in ...

Amino acid uptake in Arabidopsis [PDF]

, 2008
Nitrogen (N) is essential for all living organisms and is considered to be the limiting factor for plant growth in many ecosystems. Although generally believed to rely on mineral N to fulfill their N needs, plants have also been found to access organic N
