Methionine Nutrition and Metabolism: Insights from Animal Studies to Inform Human Nutrition.

Journal of NutriLife, 2020
Methionine is a nutritionally indispensable amino acid, and is unique among indispensable amino acids due to its sulfur atom. Methionine is involved in cysteine synthesis via the transsulfuration pathway, which is rate limiting for the key antioxidant ...

Methionine metabolism, functions, and application in swine

Animal Nutrition
Methionine (Met) is the only sulfur-containing essential amino acid for animals and is the second or third limiting amino acid in swine diets. It plays a role not only in protein synthesis, but also as an important methyl donor to participate in various ...

Imaging Active Infection in vivo Using D-Amino Acid Derived PET Radiotracers. [PDF]

, 2017
Occult bacterial infections represent a worldwide health problem. Differentiating active bacterial infection from sterile inflammation can be difficult using current imaging tools. Present clinically viable methodologies either detect morphologic changes

Analysis of S-Adenosylmethionine and S-Adenosylhomocysteine: Method Optimisation and Profiling in Healthy Adults upon Short-Term Dietary Intervention

Metabolites, 2022
S-adenosylmethionine (SAM) is essential for methyl transfer reactions. All SAM is produced de novo via the methionine cycle. The demethylation of SAM produces S-adenosylhomocysteine (SAH), an inhibitor of methyltransferases and the precursor of ...

Methionine metabolism and methyltransferases in the regulation of aging and lifespan extension across species

Aging Cell, 2019
Methionine restriction (MetR) extends lifespan across different species and exerts beneficial effects on metabolic health and inflammatory responses. In contrast, certain cancer cells exhibit methionine auxotrophy that can be exploited for therapeutic ...

Life span extension by glucose restriction is abrogated by methionine supplementation: Cross-talk between glucose and methionine and implication of methionine as a key regulator of life span

Science Advances, 2020
Yeast cells lower their intracellular methionine level in response to glucose restriction to regulate metabolism and life span. Caloric restriction (CR) is known to extend life span across species; however, the molecular mechanisms are not well ...

Methionine 129 variant of human prion protein oligomerizes more rapidly than the valine 129 variant - Implications for disease susceptibility to Creutzfeldt-Jakob disease [PDF]

, 2004
The human PrP gene (PRNP) has two common alleles that encode either methionine or valine at codon 129. This polymorphism modulates disease susceptibility and phenotype of human transmissible spongiform encyphalopathies, but the molecular mechanism by ...

Bigheaded Carp-Based Meal as a Sustainable and Natural Source of Methionine in Feed for Ecological and Organic Poultry Production

Journal of Applied Poultry Research, 2019
SUMMARY: High-quality protein feeds are needed in ecological and organic poultry production. Feeds that are rich in methionine (MET) are particularly important because synthetic amino acids are generally prohibited in organic livestock production ...
