A chloroplastic RNA ligase activity analogous to the bacterial and archaeal 2 '-5 ' RNA ligase [PDF]

, 2012
[EN] Bacteria and archaea contain a 2'-5' RNA ligase that seals in vitro 2',3'-cyclic phosphodiester and 5'-hydroxyl RNA termini, generating a 2',5'-phosphodiester bond. In our search for an RNA ligase able to circularize the monomeric linear replication

Role of polynucleotide kinase/phosphatase in mitochondrial DNA repair [PDF]

, 2011
Mutations in mitochondrial DNA (mtDNA) are implicated in a broad range of human diseases and in aging. Compared to nuclear DNA, mtDNA is more highly exposed to oxidative damage due to its proximity to the respiratory chain and the lack of protection ...

Chemical Syntheses of 3′ and 5′ Phosphorylated Oligonucleotides: An Overview

European Journal of Organic Chemistry, Volume 29, Issue 21, 4 June 2026.
This review provides an overview of the various chemical methods employed in the synthesis of oligonucleotides bearing a phosphate group at their 3′ or 5′ end. Notably, it presents modified phosphoramidites and supports developed for this purpose. Oligonucleotides (ON) with a phosphate monoester group at their 3′ or 5′ end have applications in many ...

Ribozymes for RNA‐Catalyzed RNA Methylation and Labeling

Angewandte Chemie International Edition, Volume 65, Issue 23, 1 June 2026.
Ribozymes are powerful tools for site‐specific RNA modification. Their activities range from installing tags and fluorophores to generating natural RNA methylations, making them valuable tools to uncover the many functions that RNA plays in nature.

5‐Methylcytosine Analysis of miRNAs in Minimal Change Disease

Biotechnology and Applied Biochemistry, Volume 73, Issue 3, Page 1137-1150, June 2026.
ABSTRACT Minimal change disease (MCD) is a glomerular disorder, which is the most common cause of nephrotic syndrome in children. Additionally, the prevalence of MCD in adults has been increasing in recent years. During protein synthesis, noncoding RNAs can be regulated through a variety of modifications, which helps preserve biological diversity and ...

RXR Gamma Enables Oligodendrocyte Differentiation by Suppressing Sonic Hedgehog Signaling

Glia, Volume 74, Issue 6, June 2026.
Using pharmacogenetic approaches, Baldassarro et al. demonstrate that RXRγ suppresses the SHH signaling pathway in OPCs to ensure their efficient differentiation following T3 stimulation. Accordingly, Rxrg−/− OPCs displayed compromised differentiation which was normalized by the pharmacological inhibition of the hyperactive SHH pathway.

Clinicopathological characteristics of patients with inoperable non‐small cell lung cancer harboring circulating NRF2 pathway mutations

The Journal of Pathology, Volume 269, Issue 2, Page 164-181, June 2026.
Abstract Lung cancer is the leading cause of global cancer‐related morbidity and mortality, with tobacco smoking as its strongest risk factor. Nuclear factor erythroid 2‐related factor 2 (NRF2) is a redox‐regulated transcription factor frequently dysregulated in non‐small cell lung cancer (NSCLC), leading to aggressive disease and resistance to therapy.

Redox environment modulates aggregation of ataxin‐3 in vitro — Implications for drug screening of cysteine‐rich proteins

The FEBS Journal, Volume 293, Issue 11, Page 3376-3398, June 2026.
Redox environment modulates in vitro aggregation of Ataxin‐3, the protein implicated in spinocerebellar ataxia type 3. Reducing conditions stabilize native monomers and prevent aggregation, whereas oxidative conditions promote the formation of non‐native conformers and disulfide‐linked oligomers within the Josephin domain (JD).

Biochemical Characterization Of The Rtcb Family Of Rna Ligases In Bacteria [PDF]

, 2016
All known life relies on the proper transmission of genetic information through DNA and RNA to protein. The protection of this information is critical, and rejoining of broken DNA or RNA strands by ligases is essential for maintenance of genetic ...
