This paper uses a game theoretic framework based on Nash equilibria to model and simulate competing pathways of amyloid-β aggregation in the presence of fatty acids, showing how rate constants control oligomer formation.

The paper reports the crystal structure of a thermostable DGR variable protein from Thermus aquaticus and confirms its CLec-fold structure, supporting its potential for molecular display applications.

The paper demonstrates that the DGR reverse transcriptase and Avd protein complex selectively mutagenize adenines during cDNA synthesis from DGR RNA templates.

The paper shows that Daple transcript isoforms V1 and V2 in peripheral blood predict melanoma prognosis, with V2 improving survival and V1 worsening it.

The paper identifies two Daple/CCDC88C isoforms, showing they cooperatively suppress tumor growth but only the full-length isoform triggers EMT and invasion, with aspirin affecting their expression.

This study shows that Akt/PKB enhances non-canonical Wnt signals by phosphorylating Daple, which compartmentalizes β-catenin to cell-cell contact sites, suppressing colony growth.

This study identifies Daple as a convergence point for Wnt, growth factor, and G-protein signaling in cancer, showing its role in tumor progression and poor prognosis in colorectal cancer.
