ST6GAL1‐Mediated Sialylation Stabilizes PD‐L1 and Drives Immunosuppressive Tumor Microenvironment in Colorectal Cancer

Advanced Science, EarlyView.
ST6GAL1 plays a critical role in tumor progression and immune regulation in colorectal cancer (CRC). Its depletion significantly suppresses the malignant phenotype of CRC cells and enhances the efficacy of anti‐PD‐L1 therapy. High ST6GAL1 expression promotes an immune‐activated tumor microenvironment (TME), characterized by increased infiltration of ...

Hypoglycemia Induces Diabetic Macrovascular Endothelial Dysfunction via Endothelial Cell PANoptosis, Macrophage Polarization, and VSMC Fibrosis

Advanced Science, EarlyView.
This study investigates hypoglycemia‐induced diabetic macrovascular endothelial dysfunction. It reveals that hypoglycemia triggers ZBP1‐dependent PANoptosis of endothelial cells, proinflammatory polarization of macrophages, and fibrosis of vascular smooth muscle cells (VSMCs) in diabetic mice.

LEDGF Binds H3R17me2a Promoting De Novo Nucleotide Biosynthesis in SETD2 Mutant Clear Cell Renal Cell Carcinoma

Advanced Science, EarlyView.
In SETD2‐mutant ccRCC, the original LEDGF recognition of the H3K36me3 regulatory axis no longer exists. LEDGF interacts with CARM1‐dependent H3R17me2a regulating the transcription of key enzymes in the de novo synthesis pathway. The abnormally elevated LEDGF leads to the accumulation of purine nucleotides in SETD2‐mutant ccRCC, thereby satisfying the ...

Purinosomes involved in the regulation of tumor metabolism: current progress and potential application targets

Frontiers in Oncology
The core of tumor cell metabolism is the management of energy metabolism due to the extremely high energy requirements of tumor cells. The purine nucleotide synthesis pathway in cells uses the purinosomes as an essential spatial structural complex.

Metabolic Stress‐Induced Choline Kinase α (CHKA) Activation in Endothelial Subpopulation Contributes to Diabetes‐Associated Microvascular Dysfunction

Advanced Science, EarlyView.
This study uncovers CHKA as a pivotal driver of vascular dysfunction in diabetic retinopathy and highlights its role in endothelial dysfunction through NAD⁺‐SIRT1‐Notch signaling. Single‐cell and functional analyses, combined with clinical and genetic validation, suggest CHKA as a promising therapeutic target for the prevention and treatment of ...

Purine metabolism in Methanococcus vannielii [PDF]

Journal of Bacteriology, 1993
Methanococcus vannielii is capable of degrading purines to the extent that each of these purines may serve as the sole nitrogen source for growth. Results presented here demonstrate that purine degradation by M. vannielii is accomplished by a route similar to that described for clostridia.

Nucleotides as an Anti‐Aging Supplementation in Older Adults: A Randomized Controlled Trial (TALENTs study)

Advanced Science, EarlyView.
The TALENTs randomized controlled trial evaluates the potential of nucleotides supplementation as an anti‐aging intervention in older adults. After 19 weeks, nucleotides supplementation significantly reduces DNA methylation age, suggesting a delay in epigenetic aging, and improves insulin sensitivity without severe adverse events.

Regulation of Purine Metabolism in Lymphocytes

Experimental Biology and Medicine, 1985
Three general questions regarding nucleosides and lymphocytes are discussed: (a) Why are so many measurements being made of adenosine deaminase activity, what do the results mean, and why is there still disagreement about some of the conclusions; (b) what do we understand about nucleosides and lymphocyte death; and (c) to what extent do we really ...

The GGH/HuR Complex Binds and Stabilizes mRNAs to Maintain Tumor Cell Cycle and DNA Replication

Advanced Science, EarlyView.
Despite its canonical role in inhibiting DNA synthesis, GGH promotes tumor growth as a novel RNA‐binding protein. GGH binds GC‐rich 5′UTRs (e.g., CDC6/CCND1), recruits HuR to form a ternary complex that stabilizes mRNA via circular conformation, fueling DNA replication and the cell cycle. Targeting this axis suppresses NSCLC progression.

Metabolic factors determining the effectiveness of hypouricemic treatment of gouty arthritis

Bolʹ, Sustavy, Pozvonočnik, 2018
Background. The treatment of some forms of arti­cular pathology with gout remains insufficiently effective, and often it’s impossible to achieve normal indicators of uricemia on the background of uric acid-normalizing medicines.
