Clinofibrate Disrupts the SNORA80B/YTHDC1‐Driven M6A Modification to Suppress Cholesterol Metabolism and Cisplatin Resistance in ESCC

Advanced Science, EarlyView.
This study uncovers a non‐canonical role of SNORA80B in ESCC, showing it mediates AR‐driven metabolic reprogramming via N⁶‐methyladenosine (m6A) methylation. By binding YTHDC1, SNORA80B stabilizes cholesterol‐metabolic enzyme mRNAs and promotes tumor progression. The FDA‐approved drug clinofibrate inhibits SNORA80B by disrupting cholesterol homeostasis,

The Compartmentation of Acetyl-Coenzyme A Carboxylase in Plants [PDF]

Plant Physiology, 1995
Although the biochemical pathways for fatty acid synthesis are more or less similar in plants and animals (Harwood, 1988), there is a major cell biological difference between these two groups of eukaryotes. In plants, the major site of fatty acid synthesis is the plastid, an organelle absent from the animal cell.

NAD⁺ Reduction in Glutamatergic Neurons Induces Lipid Catabolism and Neuroinflammation in the Brain via SARM1

Advanced Science, EarlyView.
NAD⁺ homeostasis maintains neuronal integrity through opposing actions of NMNAT2 and SARM1. Loss of NMNAT2 in glutamatergic neurons reprograms cortical metabolism from glucose to lipid catabolism, depletes lipid stores, and triggers inflammation and neurodegeneration.

The Role of Acetyl-Coenzyme A Synthetase in Arabidopsis [PDF]

Plant Physiology, 2008
The acs1 knockout mutant that has a disruption in the plastidic acetyl-coenzyme A (CoA) synthetase (ACS; At5g36880) gene was used to explore the role of this protein and plastidic acetate metabolism in Arabidopsis (Arabidopsis thaliana). Disruption of the ACS gene decreased ACS activity by 90% and largely blocked the incorporation of exogenous (14)C ...

Balanced Expression of the Diiron Oxygenase BioE Is Essential for Biotin Homeostasis in Elizabethkingia meningoseptica

Advanced Science, EarlyView.
BioE is a new diiron oxygenase that catalyzes the conversion of long‐chain acyl groups into pimeloyl thioester, initiating biotin synthesis. The overexpression of EmBioE disrupts lipid metabolic homeostasis, requiring repressor BioL to maintain a balance between long‐chain fatty acids and biotin synthesis.

Harnessing Photoenzymatic Systems for Intermolecular C–H Fluorination

Angewandte Chemie, EarlyView.
Despite the remarkable versatility of enzymes for catalyzing complex organic transformations under mild aqueous conditions, no biocatalytic system has been reported for intermolecular C–H fluorination. A radical photoenzymatic approach is introduced that leverages a designed de novo protein scaffold with an unnatural amino acid to achieve precise ...

ACSL5 Regulates Glucose Metabolism and Chemotherapy Sensitivity in Colorectal Cancer Cells under Glutamine Deficiency

Advanced Science, EarlyView.
Glutamine deprivation triggers ACSL5 upregulation in tumor cells, sustaining their viability via dual metabolic rewiring programs. ACSL5 enhances glycolysis by relieving p53's inhibition of PGAM1 while also sustaining mitochondrial respiration and TCA cycle flux through promoting IDH2 dimerization.

Acetate Revisited: A Key Biomolecule at the Nexus of Metabolism, Epigenetics, and Oncogenesis – Part 2: Acetate and ACSS2 in Health and Disease

Frontiers in Physiology, 2020
Acetate, the shortest chain fatty acid, has been implicated in providing health benefits whether it is derived from the diet or is generated from microbial fermentation of fiber in the gut.
