Regulation of purine nucleotide metabolism as a pharmacological target [PDF]

, 2017
Purine nucleotides are essential basic building blocks for DNA and RNA synthesis. They can also serve as energy storage and transfer unit and play an important role in cell signalling and regulation of variety of biochemical processes.

Lactylation‐Driven PROS1‐TYRO3‐CARF Signaling Promotes Therapy‐Induced Senescence Escape and Radioresistance in Meningioma

Advanced Science, EarlyView.
A glycolysis‐driven epigenetic switch promotes therapy resistance in meningioma. Increased lactate production enhances histone H3K27 lactylation, which activates PROS1 secretion. Secreted PROS1 engages TYRO3 signaling to degrade the senescence regulator CARF, allowing cancer cells to escape growth arrest.

Soft Interactions, Rather Than Crowder Size, Determine Deviations From Arrhenius‐Like Kinetics of Phosphofructokinase‐1

Angewandte Chemie, EarlyView.
Our study investigates macromolecular crowding effects in the Arrhenius‐like and non‐Arrhenius temperature regimes of the human platelet isoform of phosphofructokinase‐1 (PFKP). The results reveal how PFKP maintains temperature robustness of catalytic activity in differently crowded environments.

NEK6 dampens FOXO3 nuclear translocation to stabilize C-MYC and promotes subsequent de novo purine synthesis to support ovarian cancer chemoresistance

Cell Death and Disease
De novo purine synthesis metabolism plays a crucial role in tumor cell survival and malignant progression. However, the specific impact of this metabolic pathway on chemoresistance in ovarian cancer remains unclear.

Purine Metabolism in Friedreich's Ataxia [PDF]

Canadian Journal of Neurological Sciences / Journal Canadien des Sciences Neurologiques, 1978
SUMMARY:In a detailed investigation of nucleotide synthesis, intercom'ersion and degradation, no difference was found between subjects with Friedreich's Ataxia and normal controls. It appears improbable that this disorder is related to a primary defect in purine metabolism.

Bioenergetic Materials for Tissue Regeneration: Modulating Metabolism to Promote Cellular Anabolism

Advanced Science, EarlyView.
Bioenergetic materials (BEMs) modulate cellular metabolism to promote tissue regeneration. Their principal mechanisms of action include metabolic substrate supplementation, metabolic enzyme modulation, organelle transfer, electrical current regulation, redox homeostasis modulation, and oxygen tension modulation.

RNA Organelles in DNA‐Based Artificial Cells Provide Spatial Aptamer Functions and Enhanced Signal Processing

Angewandte Chemie, EarlyView.
Multiphase DNA–RNA artificial cells integrate a protective DNA shell, a transcriptionally active DNA core, and a functional RNA organelle. Spatial compartmentalization enables signal generation, external protein expression, and selective recapture via RNA aptamers. ABSTRACT Naturally occurring biomolecular condensates orchestrate key cellular processes

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.

Stimulation of OGG1 Enhances Oxidative DNA Damage Repair and Protects Against Acute Liver Failure by Acetaminophen

Advanced Science, EarlyView.
Chemical switching of OGG1 by CMM‐98 accelerates oxidative DNA damage repair and enhances hepatocyte resilience during acetaminophen‐induced acute liver injury. By promoting efficient processing of OGG1‐generated repair intermediates, CMM‐98 reduces oxidative damage, preserves cellular integrity, and protects against acute liver failure, identifying ...
