Compound Library Screening Identified Cladribine as a Novel Radiosensitizer for Prostate Cancer

open access: yesCancer Science, EarlyView.
The combination of cladribine and irradiation significantly suppressed the growth of DU145‐derived tumors compared with the DMSO plus irradiation group in the mouse model. In addition, it also elevated the percentage of γH2AX‐positive cells after irradiation.

RRM2 (ribonucleotide reductase M2) [PDF]

open access: yesAtlas of Genetics and Cytogenetics in Oncology and Haematology, 2014
Ribonucleotide reductase subunit M2 (RRM2) is located in chromosome-2 p25-p24, converts ribonucleotides to deoxynucleotides which is required for DNA polymerization and repair. It has been shown that RMM2 plays a key role in DNA synthesis, cell growth, and drug resistance of cancer cells. There is accumulating evidence that alteration in the expression

Thioredoxin reductase as a target enzyme for electrophilic anticancer drugs [PDF]

open access: yes, 2011
Induced production of reactive oxygen species (ROS) is a common attribute of most cancer cells. One strategy for cancer cells to maneuver the increased and potentially toxic levels of ROS is to induce the expression of cellular antioxidants and ...

Taxonomic and functional shifts in the microbiome of severely obese, prediabetic patients: Ketogenic diet versus energy‐matched standard diet

open access: yesDiabetes, Obesity and Metabolism, EarlyView.
Abstract Aims Obesity and type 2 diabetes mellitus (T2DM) are among the leading global health challenges of the 21st century. While caloric restriction remains the cornerstone of weight loss interventions, ketogenic diets (KD), characterised by low carbohydrate and high fat intake, have been shown to improve metabolic health partly by modulating the ...

Function and Regulation of Yeast Ribonucleotide Reductase: Cell Cycle, Genotoxic Stress, and Iron Bioavailability

open access: yesBiomedical Journal, 2013
Ribonucleotide reductases (RNRs) are essential enzymes that catalyze the reduction of ribonucleotides to desoxyribonucleotides, thereby providing the building blocks required for de novo DNA biosynthesis.

A short peptide derived from late embryogenesis abundant proteins enhances acid tolerance in Escherichia coli via modulation of two‐component regulatory systems

open access: yesThe FEBS Journal, EarlyView.
Expression of the LEA‐K peptide in E. coli BL21 (DE3) improved bacterial viability under acidic stress (pH4), suggesting a protective function. RNA‐sequencing of LEA‐K‐expressing vs. non‐expressing cells revealed 283 differentially expressed genes (DEGs). In silico docking linked LEA‐K to two‐component systems (TCS) proteins (Rcs, BtsS/R, and EnvZ/OmpR)

Ribonucleotide reduction - horizontal transfer of a required function spans all three domains

open access: yesBMC Evolutionary Biology, 2010
Background Ribonucleotide reduction is the only de novo pathway for synthesis of deoxyribonucleotides, the building blocks of DNA. The reaction is catalysed by ribonucleotide reductases (RNRs), an ancient enzyme family comprised of three classes.

The Impact of Non-Enzymatic Reactions and Enzyme Promiscuity on Cellular Metabolism during (Oxidative) Stress Conditions. [PDF]

open access: yes, 2015
Cellular metabolism assembles in a structurally highly conserved, but functionally dynamic system, known as the metabolic network. This network involves highly active, enzyme-catalyzed metabolic pathways that provide the building blocks for cell growth ...

KRP3 Stability Controls Rice Plant Architecture and Productivity via MPK3‐Mediated Phosphorylation

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Yield is a critical agronomic trait in cereal crops, shaped by factors like tiller and seed number, and seed weight. Understanding the factors governing these traits will help in improving the yield of plants. In this study, we identified an orphan gene, KRP3, belonging to cereal crops as a key regulator of rice plant architecture.

Reannotation of the Ribonucleotide Reductase in a Cyanophage Reveals Life History Strategies Within the Virioplankton

open access: yesFrontiers in Microbiology, 2019
Ribonucleotide reductases (RNRs) are ancient enzymes that catalyze the reduction of ribonucleotides to deoxyribonucleotides. They are required for virtually all cellular life and are prominent within viral genomes.
