2,4-Epibrassinolide Enhances Drought Tolerance in Prunella vulgaris by Improving Photosynthesis, Redox Homeostasis, and Secondary Metabolism

open access: yesPlants
As a species of significant traditional medicinal importance, Prunella vulgaris is severely limited by drought stress, given its high sensitivity to this environmental constraint.

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

The neural crest‐associated gene ERRFI1 is involved in melanoma progression and resistance toward targeted therapy

open access: yesMolecular Oncology, EarlyView.
ERRFI1, a neural crest (NC)‐associated gene, was upregulated in melanoma and negatively correlated with the expression of melanocytic differentiation markers and the susceptibility of melanoma cells toward BRAF inhibitors (BRAFi). Knocking down ERRFI1 significantly increased the sensitivity of melanoma cells to BRAFi.

Plasma extrachromosomal circular DNA as a biomarker in EGFR‐targeted therapy of non‐small cell lung cancer

open access: yesMolecular Oncology, EarlyView.
Detection of extrachromosomal circular DNA (eccDNA) in plasma samples from EGFR‐mutated non‐small cell lung cancer patients. Plasma was collected before and during treatment with the EGFR‐tyrosine kinase inhibitor osimertinib. Plasma eccDNA was detected in all cancer samples, and the presence of the EGFR gene on eccDNA serves as a potential biomarker ...

On Infinite Root Systems

open access: yesJournal of Algebra, 2001
\textit{D. J. Winter} [J. Algebra 73, 238-247 (1981; Zbl 0489.17010)] introduced and studied finite \(ab\)-root systems. In this paper the author extends Winter's work by defining and studying infinite \(ab\)-root systems and determining conditions on a subset \(\Gamma\) of an additive abelian group with \(0 \in \Gamma\) that are equivalent to \(\Gamma\

Cytoplasmic p21 promotes stemness of colon cancer cells via activation of the NFκB pathway

open access: yesMolecular Oncology, EarlyView.
Cytoplasmic p21 promotes colorectal cancer stem cell (CSC) features by destabilizing the NFκB–IκB complex, activating NFκB signaling, and upregulating BCL‐xL and COX2. In contrast to nuclear p21, cytoplasmic p21 enhances spheroid formation and stemness transcription factor CD133.

Embeddings of root systems I: Root systems over commutative rings

open access: yesJournal of Algebra, 2009
The paper under review considers a class of reflection representations of Coxeter groups over commutative unital rings \(R\) and their corresponding root systems. For \(R=\mathbb{R}\), these include the standard (real, reduced) root systems. In general, they also include, for any (unital) subring \(Z\) of \(\mathbb{R}\), certain root systems over ...
