The newfound relationship between extrachromosomal DNAs and excised signal circles

FEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

G-Quadruplex-Forming Aptamers—Characteristics, Applications, and Perspectives

Molecules, 2019
G-quadruplexes constitute a unique class of nucleic acid structures formed by G-rich oligonucleotides of DNA- or RNA-type. Depending on their chemical nature, loops length, and localization in the sequence or structure molecularity, G-quadruplexes are ...

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

FEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Towards improved anticancer properties of the G-quadruplex-forming T40231 aptamer through increased flexibility of nucleoside residues

Scientific Reports
In this article, the T40231 aptamer, an anticancer agent, originally known for its ability to inhibit STAT3, was altered with UNAs to enhance its flexibility in the loops or G-tetrads.

Bridging the gap: Multi‐stakeholder perspectives of molecular diagnostics in oncology

Molecular Oncology, EarlyView.
Although molecular diagnostics is transforming cancer care, implementing novel technologies remains challenging. This study identifies unmet needs and technology requirements through a two‐step stakeholder involvement. Liquid biopsies for monitoring applications and predictive biomarker testing emerge as key unmet needs. Technology requirements vary by

Na+ selective structural switch from an intramolecular triplex to tetrad stabilised by non-canonical mispairs in double repeat of Arabidopsis thaliana telomere (T3AG3)2

Biochemistry and Biophysics Reports
DNA is polymorphic, as with four nucleobases, it can be configured in a number of secondary structures. The four-stranded DNA structures consisting of G-tetrads have especially been intriguing because of their proven existence in human cells.
