Comparison of Polynucleotide and Polydeoxyribonucleotide in Dermatology: Molecular Mechanisms and Clinical Perspectives [PDF]

Pharmaceutics
Polynucleotide (PN) and polydeoxyribonucleotide (PDRN) are DNA-derived biopolymers increasingly recognized for their potential in dermatology. Despite their structural similarities, PN and PDRN exhibit distinct functions due to differences in polymer ...

The NUDIX hydrolase NUDT5 influences purine nucleotide metabolism and thiopurine pharmacology [PDF]

The Journal of Clinical Investigation
Purine nucleotides are critical for nucleic acid synthesis, signaling, and cellular metabolism. Thiopurines (TPs), including 6-mercaptopurine and 6-thioguanine, are cornerstone agents for the treatment of acute lymphoblastic leukemia (ALL).

Salvage and de novo synthesis of nucleotides in Trypanosoma brucei and mammalian cells

, 2008
All living cells are dependent on nucleic acids for their survival. The genetic information stored in DNA is translated into functional proteins via a messenger molecule, the ribonucleic acid (RNA). Since DNA and RNA can be considered as polymers of nucleotides (NTPs), balanced pools of NTPs are crucial to nucleic acid synthesis and repair. The de novo

CoCl₂-Mimicked Endothelial Cell Hypoxia Induces Nucleotide Depletion and Functional Impairment That Is Reversed by Nucleotide Precursors

Biomedicines, 2022
Chronic hypoxia drives vascular dysfunction by various mechanisms, including changes in mitochondrial respiration. Although endothelial cells (ECs) rely predominantly on glycolysis, hypoxia is known to alter oxidative phosphorylation, promote oxidative ...

Transcriptome Sequencing Analysis of circRNA in Skeletal Muscle between Fast- and Slow-Growing Chickens at Embryonic Stages

Animals, 2022
Skeletal muscle growth has always been the focus of the broiler industry, and circRNAs play a significant role in this process. We collected leg muscles of slow- and fast-growing Bian chicken embryos in the study at 14 (S14 and F14) and 20 (S20 and F20 ...

A nuclear orthologue of the dNTP triphosphohydrolase SAMHD1 controls dNTP homeostasis and genomic stability in Trypanosoma brucei

Frontiers in Cellular and Infection Microbiology, 2023
Maintenance of dNTPs pools in Trypanosoma brucei is dependent on both biosynthetic and degradation pathways that together ensure correct cellular homeostasis throughout the cell cycle which is essential for the preservation of genomic stability. Both the

Re-Discovery of Pyrimidine Salvage as Target in Cancer Therapy

Cells, 2022
Nucleotides are synthesized through two distinct pathways: de novo synthesis and nucleoside salvage. Whereas the de novo pathway synthesizes nucleotides from amino acids and glucose, the salvage pathway recovers nucleosides or bases formed during DNA or ...

From a drug repositioning to a structure-based drug design approach to tackle acute lymphoblastic leukemia

Nature Communications, 2023
Cancer cells utilize the main de novo pathway and the alternative salvage pathway for deoxyribonucleotide biosynthesis to achieve adequate nucleotide pools.

Acyclic nucleoside phosphonates with adenine nucleobase inhibit Trypanosoma brucei adenine phosphoribosyltransferase in vitro

Scientific Reports, 2021
All medically important unicellular protozoans cannot synthesize purines de novo and they entirely rely on the purine salvage pathway (PSP) for their nucleotide generation.

Nucleoside Metabolism Is Induced in Common Bean During Early Seedling Development

Frontiers in Plant Science, 2021
Nucleoside hydrolases (NSH; nucleosidases) catalyze the cleavage of nucleosides into ribose and free nucleobases. These enzymes have been postulated as key elements controlling the ratio between nucleotide salvage and degradation.
