Amino acid metabolism in primary bone sarcomas

Frontiers in Oncology, 2022
Primary bone sarcomas, including osteosarcoma (OS) and Ewing sarcoma (ES), are aggressive tumors with peak incidence in childhood and adolescence. The intense standard treatment for these patients consists of combined surgery and/or radiation and maximal

Effect of oxygen tension on the amino acid utilisation of human embryonic stem cells

, 2014
Background/aims: human embryonic stem cells (hESCs) are a potential source of cells for treatment of many degenerative diseases, but in culture have a propensity to spontaneously differentiate, possibly due to suboptimal conditions. Culture at low oxygen

Effects of dietary long-chain polyunsaturated fatty acids on plasma amino acids and indices of protein metabolism in infants: Results from a randomized clinical trial [PDF]

, 1998
Background/Aim: Previous studies in vitro and in animals in vivo found that alpha-linolenic acid (C18:3 omega 3) may enhance oxidative damage of essential amino acids.

Effects of D-amino acid oxidase inhibition on memory performance and long-term potentiation in vivo [PDF]

, 2013
N-methyl-d-aspartate receptor (NMDAR) activation can initiate changes in synaptic strength, evident as long-term potentiation (LTP), and is a key molecular correlate of memory formation.

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.
