CpDNA-based species identification and phylogeography: application to a complex of African tropical tree species [PDF]

open access: yes, 2010
Despite their importance as a hotspot of biodiversity, the history of the African tropical lowland rainforests is poorly known. In particular the respective influence of past climatic factors, environmental heterogeneity and physical barriers on the ...

The newfound relationship between extrachromosomal DNAs and excised signal circles

open access: yesFEBS 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 ...

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

open access: yesFEBS 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.

Application of a multiplex polymerase chain reaction (mPCR) assay to detect fraud by substitution of bovine meat cuts with water buffalo meat in Northern Brazil

open access: yesCyTA - Journal of Food, 2019
The adulteration of meat products can affect the confidence of consumers and the market, leading to negative impacts on the economy. Accordingly, product authenticity has become an important issue in modern society. Therefore, our study aimed to optimize

Dytiscidae and Noteridae of Wisconsin (Coleoptera). V. Distribution, Habitat, Life Cycle, and Identification of Species of Hydroporinae, Except \u3ci\u3eHydroporus\u3c/i\u3e Clairville Sensu Lato [PDF]

open access: yes, 2017
Thirty species in 11 genera of Hydroporinae were collected in Wisconsin over the past 32 years, excluding those in Hydorporus s.l. Fourteen species of Hygrotus were found; other genera were represented by one to four species.

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

open access: yesFEBS 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).

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Sequence analysis of the second internal Transcribed spacer (ITS2) region of rDNA for species identification of trichostrongylus nematodes isolated from domestic livestock in Iran [PDF]

open access: yes, 2012
Background: Infectivity of herbivores with Trichostrongylus nematodes is widespread in many countries, having a major economic impact on breeding, survivability, and productivity of domestic livestock.
