Dissipatively Fueled Unidirectionally Communicating DNA Circuits That Control Biocatalysis

Angewandte Chemie, EarlyView.
Unidirectionally communicating, out‐of‐equilibrium DNA circuits are used to control enzyme activity. Transient DNAzyme activation generates fuel for temporal trypsin activation. Cyclic fuel‐driven hybridization and exonuclease‐mediated reset enable precise control over lifetimes, which is analyzed using combined experimental and computational ...

Automatically Defining Protein Words for Diverse Functional Predictions Based on Attention Analysis of a Protein Language Model

Advanced Science, EarlyView.
Understanding protein sequence–function relationships remains challenging due to poorly defined motifs and limited residue‐level annotations. An annotation‐agnostic framework is introduced that segments protein sequences into “protein words” using attention patterns from protein language models.

The Role of Chemistry Across Disciplines From Humanities to Life Sciences in Understanding Complexity and Emergence

Angewandte Chemie, EarlyView.
This study explores the origins of life by linking prebiotic chemistry, the emergence of information‐carrying molecules such as RNA and proteins, and philosophical questions about consciousness. The study emphasizes the role of molecular evolution in the Central Dogma and provides insights into the chemical origins of biology and the basis of life's ...

Deciphering the Impact of RAC1‐SPTAN1 in ARPKD Cystogenesis Using Multifaceted Models

Advanced Science, EarlyView.
Distal/connecting tubules expressing SLC8A1 have been suggested as a potential origin of ARPKD cysts. SPTAN1 has been identified as a key molecule in ARPKD cyst formation. Restoring SPTAN1 in PKHD1−/− organoids reduced cyst formation, normalized calcium levels, and decreased RAC1/c‐FOS expression, highlighting SPTAN1's role in ARPKD and the potential ...

Small‐Molecule Activation of mRNA Translation by Click‐to‐Release Reaction in Cells

Angewandte Chemie, EarlyView.
A new method to control mRNA activity using bioorthogonal click‐to‐release reactions is presented. The 5′ cap is modified with a trans‐cyclooctene (TCO) that quickly reacts with hydroxyaryl‐tetrazines and efficiently releases the native cap 0. TCO‐capped mRNAs are initially translationally inactive but can be activated with non‐toxic, cell‐permeable ...

The Iron-Type Nitrile Hydratase Activator Protein Is A GTPase [PDF]

, 2017
The Fe-type nitrile hydratase activator protein from Rhodococcus equi TG328-2 (ReNHase TG328-2) was successfully expressed and purified. Sequence analysis and homology modeling suggest that it is a G3E P-loop guanosine triphosphatase (GTPase) within the ...

Ferroptosis: The Demise of Cells Through Phospholipid Peroxidation

Advanced Science, EarlyView.
The relative abundance of peroxidation‐resistant monounsaturated fatty acids (MUFAs) vs. peroxidation‐sensitive polyunsaturated fatty acids (PUFAs) incorporated into phospholipid (PL) is a key determinant of ferroptosis sensitivity, as the peroxidation of PL PUFA acyl chains (PUFA‐PL) disrupts membrane integrity, causing ferroptotic cell death ...

Post‐Translational Regulation of CD8+ T Cell Fate and Dysfunction in Tumor Immunity

Advanced Science, EarlyView.
This review delineates how post‐translational modifications (PTMs) function as a central regulatory interface governing CD8+ T cell activation, differentiation, persistence, and exhaustion in antitumor immunity. By integrating antigenic, metabolic, and microenvironmental cues, diverse PTM programs coordinate transcriptional and chromatin states that ...

Cytosolic Phosphoenoylpyruvate Carboxykinase Deficiency: Clinical, Biochemical, and Genetic Features of Five Non‐Finnish Patients

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Cytosolic phosphoenoylpyruvate carboxykinase (PEPCK‐C) is an essential, rate‐limiting enzyme in the gluconeogenesis pathway. PEPCK‐C deficiency presents with hypoglycaemia, hyperlactataemia and hepatopathy, and was first reported in association with bi‐allelic PCK1 variants in 2014.
