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 ...

The Bonding-Bounding Dynamic

Abstract Chapter 10 uses a survey experiment to deal with the nature of European solidarity during COVID-19: are European citizens more solidaristic with their European counterparts than with third-country citizens? It maps out a “geography of European solidarity” and shows how EU countries are more solidaristic with each other than with

Conserved structural motifs in PAS, LOV, and CRY proteins regulate circadian rhythms and are therapeutic targets

FEBS Letters, EarlyView.
Cryptochrome and PAS/LOV proteins play intricate roles in circadian clocks where they act as both sensors and mediators of protein–protein interactions. Their ubiquitous presence in signaling networks has positioned them as targets for small‐molecule therapeutics. This review provides a structural introduction to these protein families.

Water-compatible dynamic covalent bonds based on a boroxine structure

Communications Chemistry
Boroxines, resulting from the reversible dehydration of boronic acids, have been incorporated as structural units into functional materials and molecular assemblies, but their applicability is restricted to non-aqueous environments owing to their ...

Identifying Volatility Risk Premium from Fixed Income Asian Options [PDF]

We provide approximation formulas for at-the-money asian option prices to extract volatility risk premium from a joint dataset of bonds and option prices. The dynamic model generates stochastic volatility and a time-varying volatility risk premium, which

Binding branched and linear DNA structures: from isolated clusters to fully bonded gels

, 2017
The proper design of DNA sequences allows for the formation of well defined supramolecular units with controlled interactions via a consecution of self-assembling processes. Here, we benefit from the controlled DNA self-assembly to experimentally realize

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.
