Inactivation of human liver bile acid CoA:amino acid N-acyltransferase by the electrophilic lipid, 4-hydroxynonenal

Journal of Lipid Research, 2008
The hepatic enzyme bile acid CoA:amino acid N-acyltransferase (BAT) catalyzes the formation of amino acid-conjugated bile acids. In the present study, protein carbonylation of BAT, consistent with modification by reactive oxygen species and their ...

EETs Reduction Contributes to Granulosa Cell Senescence and Endometriosis‐Associated Infertility via the PI3K/AKT/mTOR Signaling Pathway

Advanced Science, EarlyView.
1) 14, 15‐EET levels were decreased in ovarian granulosa cells, follicular fluid, peritoneal fluid from endometriosis patients. 2) EETs reduction in endometriosis follicular fluid aggravated granulosa cell senescence. 3) ROS reduced 14, 15‐EET levels by upregulating EPHX2 through a mechanism involving histone methylation modification.

CoA‐dependent activation of mitochondrial acyl carrier protein links four neurodegenerative diseases

EMBO Molecular Medicine, 2019
PKAN, CoPAN, MePAN, and PDH‐E2 deficiency share key phenotypic features but harbor defects in distinct metabolic processes. Selective damage to the globus pallidus occurs in these genetic neurodegenerative diseases, which arise from defects in CoA ...

ZDHHC12 Palmitoylates HDAC8 to Promote the Progression of Hepatocellular Carcinoma Associated with a Diet High in Saturated Fatty Acids

Advanced Science, EarlyView.
This study identifies ZDHHC12 as a critical mediator of PA‐induced HCC progression. Mechanistically, PA upregulates ZDHHC12 expression through SMARCA4 activation, leading to HDAC8 palmitoylation at Cys244 which blocks HSC70‐mediated lysosomal degradation of HDAC8, thereby promoting HCC development. These findings provide novel mechanistic insights into

eIF4E Enriched Extracellular Vesicles Induce Immunosuppressive Macrophages through HMGCR‐Mediated Metabolic Rewiring

Advanced Science, EarlyView.
Here, it is revealed that ovarian cancer cells release extracellular vesicles enriched with eIF4E, which alters protein production in macrophages. This leads to increased expression of 3‐hydroxy‐3‐methyl‐glutaryl‐coenzyme A reductase (HMGCR), boosting cholesterol synthesis and activating an immunosuppressive pathway through X‐box binding protein 1 and ...

Coenzyme Q10 Modulates Remodeling Possibly by Decreasing Angiotensin-Converting Enzyme in Patients with Acute Coronary Syndrome

Antioxidants, 2018
The study aims to examine the effects of coenzyme Q10, (a bioenergetic antioxidant), on the indexes of left ventricular remodeling, oxidative damage, and angiotensin-converting enzyme (ACE) level after acute myocardial infarction (AMI) with left ...

Coenzyme A Transferase

Journal of Biological Chemistry, 1967
Abstract The following evidence supports the conclusion that the reaction catalyzed by succinyl coenzyme A:3-keto acid coenzyme A transferase proceeds through two half-reactions in a "ping-pong" mechanism with an enzyme-CoA intermediate. (a) Double reciprocal plots of the initial rates against substrate concentration for the reaction in each direction ...

WTAP Mediated m6A Modification Stabilizes PDIA3P1 and Promotes Tumor Progression Driven by Histone Lactylation in Esophageal Squamous Cell Carcinoma

Advanced Science, EarlyView.
This study reveals a new mechanism by which PDIA3P1 regulates the progression of esophageal squamous cell carcinoma (ESCC). PDIA3P1 upregulates the expression of GLUT1 and HK2, promoting glycolysis and lactate production. Lactate upregulates the lactylation level of histone H4K8 and activates the transcription of target gene BMP7, ultimately ...

ROS‐Responsive Hydrogel for Localized Delivery of Nampt and Stat3 Inhibitors Exhibits Synergistic Antitumor Effects in Colorectal Cancer Through Ferroptosis Induction and Immune Microenvironment Remodeling

Advanced Science, EarlyView.
In this study, ferroptosis in colorectal cancer cells is induced by FK866 through the NAD⁺/STAT3/GPX4 pathway. To minimize systemic toxicity, a reactive oxygen species (ROS)‐responsive hydrogel is developed to co‐deliver FK866 and C188‐9, resulting in synergistic and localized antitumor effects.
