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 ...

The Influence of Dietary Purines and Pyrimidines on Purine and Pyrimidine Biosynthesis in Man

Transfusion Medicine and Hemotherapy, 1977
Allopurinol-induced orotaciduria is reduced by dietary ribonucleic acid (RNA), RNA hydrolysate and different nucleotides. These findings are compatible with feedback regulation of pyrimidine biosynthesis by dietary nucleotides. Serum uric acid and urinary uric acid excretion on a purine-free isoenergetic diet reach a minimum after about 10 days and ...

Genetic ablation of purine salvage in Cryptosporidium parvum reveals nucleotide uptake from the host cell

Proceedings of the National Academy of Sciences of the United States of America, 2019
Significance Nucleotides are the activated building blocks for DNA and RNA as well as the major form of energy in all living organisms. Cells need to synthesize nucleotides to grow. Interference with this synthesis is thus widely used to treat infections

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 ...

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.

Single‐Cell RNA Sequencing Delineates Renal Anti‐Fibrotic Mechanisms Mediated by TRPC6 Inhibition

Advanced Science, EarlyView.
Single‐cell transcriptomics reveals how TRPC6 inhibition alters renal cell composition and gene expression in CKD. The study uncovers a novel endothelial subpopulation (ECRIN), highlights key inflammatory and fibrotic pathways, and identifies a Prnp‐driven network linked to fibrosis resolution, offering mechanistic insight into TRPC6 as a potential ...

Cancer stem-like properties and gefitinib resistance are dependent on purine synthetic metabolism mediated by the mitochondrial enzyme MTHFD2

Oncogene, 2018
Tumor recurrence is attributable to cancer stem-like cells (CSCs), the metabolic mechanisms of which currently remain obscure. Here, we uncovered the critical role of folate-mediated one-carbon (1C) metabolism involving mitochondrial ...

FLASH Irradiation Modulates Immune Responses and Accelerates Lung Recovery: A Single‐Cell Perspective

Advanced Science, EarlyView.
Single‐cell RNA sequencing reveals distinct immune responses to FLASH versus conventional dose rate irradiation in early radiation‐induced lung injury. FLASH irradiation reduces Ccrl2⁺ neutrophil infiltration, activates CD4⁺ CD40L⁺ Th cells, restrains pro‐inflammatory Mefv⁺ monocytes, and enhances epithelial repair via TGF‐β signaling, underscoring its
