ARABIDOPSIS HOMOLOG OF TRITHORAX1 impacts lateral root development by epigenetic regulation of targets involved in root system architecture

open access: yesNew Phytologist, EarlyView.
Summary Developmental processes are regulated at multiple levels, including the epigenetic level. Among the epigenetic factors, histone H3 lysine 4 (H3K4) methyltransferases contribute to active transcription of target genes, and here, we explored how the H3K4 methyltransferase ARABIDOPSIS HOMOLOG OF TRITHORAX1 (ATX1) affects Arabidopsis thaliana ...

Genetic Characterization and Role in Virulence of the Ribonucleotide Reductases of Streptococcus sanguinis [PDF]

open access: yes, 2013
Streptococcus sanguinis is a cause of infective endocarditis and has been shown to require a manganese transporter called SsaB for virulence and O2 tolerance. Like certain other pathogens, S.

The Hsp70 co-chaperone Ydj1/HDJ2 regulates ribonucleotide reductase activity.

open access: yesPLoS Genetics, 2018
Hsp70 is a well-conserved molecular chaperone involved in the folding, stabilization, and eventual degradation of many "client" proteins. Hsp70 is regulated by a suite of co-chaperone molecules that assist in Hsp70-client interaction and stimulate the ...

Biofilm modifies expression of ribonucleotide reductase genes in Escherichia coli. [PDF]

open access: yesPLoS ONE, 2012
Ribonucleotide reductase (RNR) is an essential enzyme for all living organisms since is the responsible for the last step in the synthesis of the four deoxyribonucleotides (dNTPs) necessary for DNA replication and repair.

Inhibition of Bacterial Ribonucleotide Reductases by Arabinonucleotides [PDF]

open access: yesEuropean Journal of Biochemistry, 1978
Ribonucleoside diphosphate reductase of Escherichia coli and ribonucleoside triphosphate reductase of Lactobacillus leichmannii are inhibited by the 5′-diphosphates and triphosphates of arabinosyladenine and arabinosylcytosine in vitro. Competitive inhibition with respect to substrate nucleotides occurs in the case of aCTP (Lactobacillus enzyme) and ...

Management of T‐cell malignancies: Bench‐to‐bedside targeting of epigenetic biology

open access: yesCA: A Cancer Journal for Clinicians, Volume 75, Issue 4, Page 282-307, July/August 2025.
Abstract The peripheral T‐cell lymphomas (PTCL) are the only disease for which four histone deacetylase (HDAC) inhibitors have been approved globally as single agents. Although it is not clear why the PTCL exhibit such a vulnerability to these drugs, understanding the biological basis for this activity is essential.

Quantification and expert evaluation of evidence for chemopredictive biomarkers to personalize cancer treatment. [PDF]

open access: yes, 2017
Predictive biomarkers have the potential to facilitate cancer precision medicine by guiding the optimal choice of therapies for patients. However, clinicians are faced with an enormous volume of often-contradictory evidence regarding the therapeutic ...

The Role of Iron Chelation Therapy in Colorectal Cancer: A Systematic Review on Its Mechanisms and Therapeutic Potential

open access: yesCancer Medicine, Volume 14, Issue 13, July 2025.
Iron chelation is a promising yet underexplored strategy for colorectal cancer (CRC) treatment. Iron chelators have a dual role in inhibiting and potentially promoting cancer progression. Iron chelation affects key CRC pathways, including histone methylation, NDRG1 upregulation, Wnt/β‐catenin, and p53 modulation.

Polymorphic Distribution of Human Homeostatic Iron Regulator Gene H63D rs1799945 and Clinico‐Hematological Parameters of Sickle Cell Anemia Patients: A Case‐Control Study in Northern Ghana

open access: yesHealth Science Reports, Volume 8, Issue 7, July 2025.
ABSTRACT Background and Aim The study assessed the polymorphic distribution of H63D rs1799945 of HFE gene and clinico‐hematological parameters of SCA patients. Methods Sixty sickle cell anemia (SCA) patients and 30 healthy controls without sickle cell disease between the ages of 2–38 years were selected for this case‐control study from March to July ...
