Methionine Adenosyltransferase 1a (MAT1A) Enhances Cell Survival During Chemotherapy Treatment and is Associated with Drug Resistance in Bladder Cancer PDX Mice. [PDF]

, 2019
Bladder cancer is among the top ten most common cancers, with about ~380,000 new cases and ~150,000 deaths per year worldwide. Tumor relapse following chemotherapy treatment has long been a significant challenge towards completely curing cancer.

Methionine adenosyltransferase 1a antisense oligonucleotides activate the liver-brown adipose tissue axis preventing obesity and associated hepatosteatosis

Nature Communications, 2022
High methionine and S-adenosylmethionine serum levels are related with obesity. Here the authors show that knockdown of methionine adenosyltransferase by using antisense oligonucleotides provides beneficial effects in obesity and comorbidities.

High Fat Low Carbohydrate Diet Is Linked to CNS Autoimmunity Protection

Advanced Science, EarlyView.
Mapping global epidemiological data to macronutrient supply reveals high carbohydrate, in contrast to high fat supply, associates with increased multiple sclerosis (MS) prevalence and incidence. This is confirmed in a mouse MS model, experimental autoimmune encephalomyelitis (EAE), using isocaloric diets: a high carbohydrate diet aggravates, a high ...

Methionine adenosyltransferase S-nitrosylation is regulated by the basic and acidic amino acids surrounding the target thiol [PDF]

, 1999
S-Adenosylmethionine serves as the methyl donor for many biological methylation reactions and provides the propylamine group for the synthesis of polyamines.

Plasma DNMT1 Activity for Assessing Tumor Burden and Predicting Neoadjuvant Therapy Response in Breast Cancer

Advanced Science, EarlyView.
In this work, a detection method is presented for the activity of plasma DNA methyltransferase 1 (DNMT1), namely DNMT1 Identification by Variable Activity (DIVA). DIVA can detect plasma DNMT1 at levels as low as 10−7 U mL−1, also it successfully evaluated tumor burden and predicted the neoadjuvant therapy responses of breast cancer patients.

Production of FAME biodiesel in E. coli by direct methylation with an insect enzyme. [PDF]

, 2016
Most biodiesel currently in use consists of fatty acid methyl esters (FAMEs) produced by transesterification of plant oils with methanol. To reduce competition with food supplies, it would be desirable to directly produce biodiesel in microorganisms.

Identification and Application of a Novel Patulin Degrading Enzyme From Meyerozyma guilliermondii

Advanced Science, EarlyView.
Patulin (PAT), a hazardous mycotoxin, threatens human health. A novel yeast‐derived short‐chain dehydrogenase/reductase effectively degrades PAT into nontoxic ascladiol via catalytic triad activity. The biological detoxification process has no significant effect on the quality of fresh pear juice.

The Molecular Basis of Amino Acids Sensing

Advanced Science, EarlyView.
Amino acids are essential as protein building blocks and signaling molecules, enabling metabolic regulation. Cells sense amino acid levels to control protein synthesis, maintain homeostasis, and adapt to nutritional changes. This review explores recent advances in amino acid sensing mechanisms across organisms, highlighting their roles in cellular ...

RadicalS-Adenosylmethionine Enzymes

Chemical Reviews, 2014
It was once widely held that nearly all reactions in biology were catalyzed via mechanisms involving paired electron species. Beginning approximately 40 years ago, this paradigm was repeatedly challenged as examples of enzymatic reactions involving organic radical intermediates began to emerge, and it is now well accepted that biochemical reactions ...
