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 ...

A reappraisal of the vegetation from the dinosaur-bearing Bahariya Formation (lower Cenomanian; Cretaceous), Egypt

Swiss Journal of Palaeontology
The Bahariya Formation of the northern Western Desert, Egypt, is well-known for its plentiful and diverse vertebrate fossil assemblages, especially dinosaurs, and also eminent for its rich fossil macroflora.

Does functional soil microbial diversity contribute to explain within-site plant beta-diversity in an alpine grassland and a dehesa meadow in Spain? [PDF]

, 2017
Questions: Once that the effects of hydrological and chemical soil properties have been accounted for, does soil microbial diversity contribute to explain change in plant community structure (i.e. within-site beta-diversity)?

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 ...

Complex dynamics in coevolution models with ratio-dependent functional response

, 2009
We explore the complex dynamical behavior of two simple predator-prey models of biological coevolution that on the ecological level account for interspecific and intraspecific competition, as well as adaptive foraging behavior.

Diverse functions of perineuronal nets

Acta Neurobiologiae Experimentalis, 2009
Perineuronal nets represent well-organised components of the extracellular matrix, which are surrounding cell bodies, dendrites, and axon segments of a particular class of neurones as well as forming lattice-like structures. The role of perineuronal nets is not fully elucidated yet.

Functional diversity promotes phytoplankton resource use efficiency

Journal of Ecology, 2019
Understanding the relationship between biodiversity and ecosystem functioning (BEF) is a central topic in ecology. Multi‐trait–based functional diversity has been proposed to improve mechanistic understanding of the BEF relationship; however, how trait ...

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).

Exotic species invasions undermine regional functional diversity of freshwater fish

Scientific Reports, 2019
Exotic species invasions often result in native biodiversity loss, i.e. a lower taxonomic diversity, but current knowledge on invasions effects underlined a potential increase of functional diversity.
