Anisotropic relaxation in NADH excited states studied by polarization-modulation pump-probe transient spectroscopy [PDF]

, 2020
We present the results of experimental and theoretical studies of fast anisotropic relaxation and rotational diffusion in the first electron excited state of biological coenzyme NADH in water-ethanol solutions. The experiments have been carried out by means of a novel polarization-modulation transient method and fluorescence polarization spectroscopy ...

Pyrophosphate-Dependent ATP Formation from Acetyl Coenzyme A in Syntrophus aciditrophicus, a New Twist on ATP Formation

mBio, 2016
Syntrophus aciditrophicus is a model syntrophic bacterium that degrades key intermediates in anaerobic decomposition, such as benzoate, cyclohexane-1-carboxylate, and certain fatty acids, to acetate when grown with hydrogen-/formate-consuming ...

The Regulation of Trace Metal Elements in Cancer Ferroptosis

Advanced Biology, EarlyView.
The induction of ferroptosis inhibits tumor growth, enhances anticancer efficacy, and overcomes drug resistance. Recent evidence shows nonferrous metal elements play a role in ferroptosis. This review focuses on how trace metals regulate ferroptosis processes like iron accumulation, lipid peroxidation, and antioxidant defense.

Could Duodenal Molecular Mechanisms be Involved in the Hypocholesterolemic Effect of Silicon Used as Functional Ingredient in Late‐Stage Type 2 Diabetes Mellitus?

Molecular Nutrition &Food Research, Volume 66, Issue 24, December 2022., 2022
Duodenal mucosa in early‐stage type 2 diabetes mellitus (ED), late‐stage type 2 diabetes mellitus injected with streptozotocin‐nicotinamide (STZ/NAD) (LD) and treated‐silicon LD (LD‐Si) groups. Silicon partially reversed LD group alterations: decreased absorptive area and acyl‐Coenzyme A:cholesterol acyltransferase 2 (ACAT2) levels, and increased ...

Profiling of cytosolic and peroxisomal acetyl-CoA metabolism in Saccharomyces cerevisiae.

PLoS ONE, 2012
As a key intracellular metabolite, acetyl-coenzyme A (acetyl-CoA) plays a major role in various metabolic pathways that link anabolism and catabolism. In the yeast Saccharomyces cerevisiae, acetyl-CoA involving metabolism is compartmentalized, and may ...

Correlation between ferroelectricity and torsional motion of acetyl groups in tris(4-acetylphenyl)amine observed by muon spin relaxation [PDF]

J. Appl. Phys. 137, 044102 (2025)
It is demonstrated by muon spin relaxation and resonance experiments that the switchable spontaneous polarization of the organic ferroelectric compound tris(4-acetylphenyl)amine (TAPA) is governed by the local molecular dynamics of the acetyl group.

Swelling of acetylated wood in organic liquids [PDF]

, 2005
To investigate the affinity of acetylated wood for organic liquids, Yezo spruce wood specimens were acetylated with acetic anhydride, and their swelling in various liquids were compared to those of untreated specimens. The acetylated wood was rapidly and remarkably swollen in aprotic organic liquids such as benzene and toluene in which the untreated ...

Short‐Chain Fatty Acids Modulate Anti‐ROR1 CAR T‐Cell Function and Exhaustion in an Intestinal Adenocarcinoma‐on‐Chip Model

Advanced Healthcare Materials, EarlyView.
Short‐chain fatty acids modulate anti‐ROR1 chimeric antigen receptor (CAR) T‐cell function in an intestinal adenocarcinoma‐on‐chip model. Butyrate and propionate reduce cytotoxicity, cytokine release, and infiltration by inducing a regulatory T‐cell phenotype and T‐cell exhaustion via histone deacetylase inhibition.

Acetyl-CoA synthetase activity is enzymatically regulated by lysine acetylation using acetyl-CoA or acetyl-phosphate as donor molecule

Nature Communications
The AMP-forming acetyl-CoA synthetase is regulated by lysine acetylation both in bacteria and eukaryotes. However, the underlying mechanism is poorly understood.
