Exudates of dominant plants regulate rhizospheric soil total and available heavy metals and facilitates natural restoration succession in an abandoned metal mining area

Frontiers in Environmental Science
Soil degradation caused by activities such as mining is a severe global environmental issue that drastically disrupts ecosystems. Utilizing plants and their root secretions for ecological remediation is a crucial pathway to restoring these damaged lands.

Multiple ETS family transcription factors bind mutant p53 via distinct interaction regions

FEBS Letters, EarlyView.
Mutant p53 gain‐of‐function is thought to be mediated by interaction with other transcription factors. We identify multiple ETS transcription factors that can bind mutant p53 and found that this interaction can be promoted by a PXXPP motif. ETS proteins that strongly bound mutant p53 were upregulated in ovarian cancer compared to ETS proteins that ...

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 ...

Liouville Field Theory on Hyperelliptic surface

, 1996
Liouville field theory on hyperelliptic surface is considered. The partition function of the Liouville field theory on the hyperelliptic surface are expressed as a correlation function of the Liouville vertex operators on a sphere and the twist fields ...

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).

Mitigating cadmium toxicity in crops: Agronomic measures to regulate uptake and tolerance mechanisms

Plant Stress
Cadmium (Cd), a highly toxic heavy metal, disrupts all stages of crop growth and poses serious threats to human health through its accumulation in the food chain. To address this challenge, numerous studies explored a range of agronomic measures aimed at

Dual-well potential field function for articulated manipulator trajectory planning

Alexandria Engineering Journal, 2016
A new attractive potential field function is proposed in this paper for manipulator trajectory planning. Existing attractive potential field constructs a global minimum through which maneuvering objects move down the gradient of the potential field ...
