Metabolism and function of coenzyme Q

open access: yesBiochimica et Biophysica Acta (BBA) - Biomembranes, 2004
Coenzyme Q (CoQ) is present in all cells and membranes and in addition to be a member of the mitochondrial respiratory chain it has also several other functions of great importance for the cellular metabolism. This review summarizes the findings available to day concerning CoQ distribution, biosynthesis, regulatory modifications and its participation ...

KMT5C‐Mediated H4K20me3 Recruits EWSR1 to Propel Clear Cell Renal Cell Carcinoma Progression via Regulating ACADM Transcription and m6A Modification

open access: yesMed Research, EarlyView.
A schematic diagram illustrating the KMT5C‐H4K20me3‐EWSR1‐ACADM signaling axis and its role in ccRCC progression. Key Outcomes: KMT5C/H4K20me3 are upregulated in ccRCC and predict poor prognosis. EWSR1 is a novel noncanonical H4K20me3 reader in ccRCC. KMT5C/EWSR1 co‐repress ACADM via transcription and m6A modification. A‐196 + sunitinib synergistically

Elevation of Stearoyl‐Coenzyme A Desaturase and Monounsaturated Fatty Acids in Parkinson's Disease Serum

open access: yesMovement Disorders, EarlyView.
Abstract Background Emerging evidence indicates that dysregulation of monounsaturated fatty acids (MUFAs), synthesized by the enzyme stearoyl‐coenzyme A desaturase (SCD), impacts on α‐synuclein pathology in the Parkinson's disease (PD) brain. Objective The objective of this study was to analyze SCD and MUFA‐enriched lipids in the periphery of patients ...

Simple and convenient two step synthesis of 5-bromo-2,3-dimethoxy-6-methyl-1,4-benzoquinone

open access: yesGreen Processing and Synthesis, 2019
5-bromo-2,3-dimethoxy-6-methyl-1,4-benzoquinone 3, a key intermediate for preparing coenzyme Q compounds, was readily synthesized in two steps by a reaction sequence starting from the commercially available 3,4,5-trimethoxytoluene 1 via bromination and ...

Presynaptic Congenital Myasthenic Syndromes

open access: yesMuscle &Nerve, EarlyView.
ABSTRACT Presynaptic congenital myasthenic syndromes (CMS) encompass a large number of rare neurologic disorders caused by impaired release of acetylcholine (ACh) from motor nerve terminals. There are two main groups of presynaptic CMS: one in which the amount of ACh in synaptic vesicles (SV) is diminished and another in which the mechanism of synaptic

The continuing significance of chiral agrochemicals

open access: yesPest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

TcALS knockdown accelerates metamorphosis via insulin signaling in Tribolium castaneum

open access: yesInsect Science, EarlyView.
RNAi silencing of TcALS accelerates larva‐to‐pupa metamorphosis in Tribolium castaneum. Abstract Insect metamorphosis is an evolutionary adaptation precisely regulated by nutritional and hormonal cues. The red flour beetle Tribolium castaneum, a major stored‐product pest, serves as an excellent model for studying this process.

High‐Altitude Adaptation of Frogs (Case Study: Nanorana parkeri): From Physiological Phenotypes to AltitudeOmics

open access: yesIntegrative Zoology, EarlyView.
High altitudes are challenging for the animals that inhabit these environments. The Xizang plateau frog (Nanorana parkeri) survives in high‐altitude environments through a synergistic strategy of metabolic remodeling and protein expression adjustment to optimize energy efficiency and enhance cellular protection.

Deficiency of Mitochondrial Fatty Acid Enzyme, CPT1A, Underlies Airway Epithelial Barrier Dysfunction in Severe Asthma

open access: yesAllergy, EarlyView.
Mitochondrial fatty acid enzyme, CPT1A, is deficient in the airway epithelium of severe asthma patients. Restoration of CPT1A expression improved epithelial barrier integrity via increasing mitochondrial respiration and ATP production in airway epithelial cells. Restoration of deficient epithelial CPT1A may represent a new treatment approach for severe
