Pathological Copper Overload Reprograms SOD1 Activation via COMMD1 to Promote Senescence and Fibrosis

Advanced Science, EarlyView.
This study uncovers a previously unrecognized copper‐COMMD1‐SOD1 regulatory axis, revealing that pathological copper overload paradoxically suppresses SOD1 activity by promoting COMMD1‐dependent disruption of SOD1 homodimerization. These findings redefine the regulatory role of copper in SOD1 biology and provide novel mechanistic insight into the ...

Inhibition and Formation of Amyloid Fibrils in the Bulk and at the Interface of Biomolecular Condensates

Angewandte Chemie, EarlyView.
In this review, we discuss how biomolecular condensates can inhibit amyloid aggregation in their interior, while still facilitating fibril formation at the interface between the dense and dilute phases, where molecular and mesoscale properties are likely optimal to promote protein aggregation.

A Novel Class of “Super‐Strained” Spiro Heterocycles: Gateway to 1‐Azaspiro[3.3]heptane Derivatives, and Biological Validation

Angewandte Chemie, EarlyView.
A new class of “super‐strained” spiro heterocycles—spirocyclic 1‐azabicyclo[1.1.0]butanes—was synthesized via insertion of cyclobutane‐, oxetane‐, and azetidine‐containing sulfonium reagents into substituted azirines. The stability of this new class of compounds was studied.

DNA‐Induced Entropic Gain Triggers an Allosteric Switch for Biomolecular Condensation of Heat Shock Transcription Factor 1

Angewandte Chemie, EarlyView.
Hsf1 undergoes phase separation around target DNA, activating stress‐responsive transcription. DNA binding tunes conformational dynamics of Hsf1DBD, which propagates through large‐scale domain rearrangements involving DBD–IDR interactions to regulate phase separation. This hierarchical framework illustrates how local structural events at the side chain

Machine Learning‐Enhanced Random Matrix Theory Design for Human Immunodeficiency Virus Vaccine Development

Advanced Intelligent Discovery, EarlyView.
This study integrates random matrix theory (RMT) and principal component analysis (PCA) to improve the identification of correlated regions in HIV protein sequences for vaccine design. PCA validation enhances the reliability of RMT‐derived correlations, particularly in small‐sample, high‐dimensional datasets, enabling more accurate detection of ...
