Lactylation of HMGB1 at K177 Drives Nuclear Export of TIAR to Promote Hypoxia‐Induced Stress Granule Formation

Advanced Science, EarlyView.
This study uncovers a novel mechanism in which p300‑catalyzed lactylation of HMGB1 triggers nuclear export of the HMGB1‐TIAR complex, driving TIAR‐dependent SGs formation in the cytoplasm. Mass spectrometry and mutagenesis reveals that K177 lactylation is essential for this export and subsequent SGs formation.

A Novel Regulator of Activation-Induced Cytidine Deaminase/APOBECs in Immunity and Cancer: Schrödinger’s CATalytic Pocket

Frontiers in Immunology, 2017
Activation-induced cytidine deaminase (AID) and its relative APOBEC3 cytidine deaminases boost immune response by mutating immune or viral genes. Because of their genome-mutating activities, AID/APOBECs are also drivers of tumorigenesis.

Lysosome‐Featured Cell Aggregate‐Released Extracellular Vesicles Regulate Iron Homeostasis and Alleviate Post‐Irradiation Endothelial Ferroptosis for Mandibular Regeneration

Advanced Science, EarlyView.
Lysosomal redistribution occurs via extracellular vesicles in multi‐stem cell aggregates and controls iron homeostasis for safeguarding cell aggregation. These cell aggregate‐released extracellular vesicles (CA‐EVs) rescue lysosomal impairments and exert anti‐ferroptosis effects in recipient irradiated endothelial cells.

Multipoint Coordinative Capture of Olefinic Substrates Utilizing Metal‐Carbon Bonds by Macrocyclic Complex

Angewandte Chemie, EarlyView.
We have developed a macrocyclic tetranuclear palladium complex, which has four coordination sites within its inner cavity as a host molecule. The complex captured squalene (C30H50), a linear triterpene with six C═C double bonds, through multipoint palladium‐carbon bonds, and formed a unique host‐guest complex with a folded‐squalene structure.

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

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 ...

MAMMALIAN METHYLMALONYL ISOMERASE AND VITAMIN B(12) COENZYMES.

Proceedings of the National Academy of Sciences of the United States of America, 1960
In 1955 Flavin et al.1-4 found that the main pathway of propionic acid oxidation in animal tissues proceeds via the reaction sequence propionate ATPC propionyl CoA5 ATPCOYmethylmalonyl CoA -succinyl CoA succinate.

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.

The RNA world: hypotheses, facts and experimental results. [PDF]

, 2005
A biochemical world that would have existed before the contemporary DNA-RNA-Protein world, and baptized in 1986 "The RNA World" by Walter Gilbert, such a world had already been proposed during the preceding decades by Carl Woese, Francis Crick and Leslie

The binding of oxidized coenzymes by glutamate dehydrogenase and the effects of glutarate and purine nucleotides.

Biochemical Journal, 1972
1. The binding of NAD(+) and NADP(+) to glutamate dehydrogenase has been studied in sodium phosphate buffer, pH7.0, by equilibrium dialysis. Approximate values for the dissociation constants are 0.47 and 2.5mm respectively.
