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 ...

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

FEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Using films in teaching about Africa [PDF]

, 2002
This paper begins with a brief critique of didactic approaches to teaching about Africa: Such methods do not benefit students pedagogically; they cast Western academy/academics as guardians of truth about Africa; and they cast students as possible ...

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

FEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Borders on the mind: re-framing border thinking

Ethics & Global Politics, 2008
From one viewpoint, interstate borders are simple ‘artefacts on the ground’. Borders exist for a variety of practical reasons and can be classified according to the purposes they serve and how they serve them. They enable a whole host of important political, social, and economic activities.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Technoecologies of Borders: Thinking with Borders as Multispecies Matters of Care [PDF]

Australian Feminist Studies, 2017
Reading Félix Guattari’s concept of ecology through feminist accounts of care and solidarity, and vice versa, in this article, we propose the concept of feminist technoecology as a speculative mode of thinking with borders. Rather than considering borders as lines on maps or primarily as physical arrangements, we argue that feminist technoecology ...

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...
