Multi‐Omics and ‐Organ Insights into Energy Metabolic Adaptations in Early Sepsis Onset

Advanced Science, EarlyView.
This study shows that patients at risk of sepsis have a distinct metabolite and lipid signature, including serine and aminoadipic acid, in their serum before clinical diagnosis. A mouse model of sepsis with a compatible serum signature reveals underlying metabolic changes, including mitochondrial adaptation, altered serine‐dependent purine metabolism ...

Intestinal Clock Promotes Cognitive Memory Through Adenosine Signaling

Advanced Science, EarlyView.
The intestinal clock controls the expression of an adenosine enzyme that modulates systemic adenosine level and A1R signaling in the hippocampus, and in turn, cognitive function involving long‐term potentiation and BDNF‐dependent synaptic changes.

Biocatalytic Alkylation of Ambident Nucleophiles Enables Selective N‐Functionalization of Heterocycles and Late‐Stage Modifications

Angewandte Chemie, EarlyView.
N‐alkylated heteroarenes are key structural motifs in bioactive compounds, but their regioselective synthesis via coupling of readily available azoles with haloalkanes remains very challenging. Here, we present a mild biocatalytic approach that proceeds on gram‐scale, is highly chemo‐ and regioselective, offering rapid access to valuable N‐alkylated ...

Divergent prebiotic synthesis of pyrimidine and 8-oxo-purine ribonucleotides

Nature Communications, 2017
Understanding prebiotic nucleotide synthesis is a long standing challenge thought to be essential to elucidating the origins of life on Earth. Recently, remarkable progress has been made, but to date all proposed syntheses account separately for the ...

Anti‐Icing Organogel Enables Quasi‐Homogeneous Supercooling Preservation of Mouse Hearts

Advanced Science, EarlyView.
An organogel interface with a large energy barrier for ice nucleation is proposed to enable a quasi‐homogeneous supercooling preservation for organs. This method does not rely on cryoprotectant agents or machine perfusion and can double the ex vivo storage time of mouse hearts.

Conditional Stabilization of the Hypoxia‐Inducible Factor HIF1α— Photoswitchable Stapled Peptides Prevent Elongin BC–Mediated Degradation

Angewandte Chemie, EarlyView.
Visible‐light photoswitchable peptides enable the stabilization of the hydroxylated hypoxia transcription factor 1α (HIF1α—OH) by targeting the pVHL‐EloBC interaction. Significant differences in conformation, binding, and transcription of HIF‐targeted genes between the photostationary states (PSS) were demonstrated.

Allantoin, a stress-related purine metabolite, can activate jasmonate signaling in a MYC2-regulated and abscisic acid-dependent manner

Journal of Experimental Botany, 2016
Highlight Allantoin, a stress-related purine metabolite, can activate JA responses via ABA in Arabidopsis, suggesting its possible involvement in the homeostasis of these phytohormones and their interplay in stress signaling.

Phenotypical and Genotypical Expansion of Autosomal‐Dominant KDM1A‐Related Neurodevelopmental Disorder Spectrum: A Case Report

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT KDM1A‐related neurodevelopmental disorder (CPRF, OMIM #616728) is characterized by cleft palate, global developmental delay, and distinct facial gestalt, but phenotypic knowledge of this ultra‐rare autosomal dominant disorder is limited. Here, we report on a 13‐year‐old boy with a novel heterozygous, likely pathogenic germline missense variant

A Transcriptome‐Wide Mendelian Randomization Study in Isolated Human Immune Cells Highlights Risk Genes Involved in Viral Infections and Potential Drug Repurposing Opportunities for Schizophrenia

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Schizophrenia is a neurodevelopmental psychiatric disorder characterized by symptoms of psychosis, thought disorder, and flattened affect. Immune mechanisms are associated with schizophrenia, though the precise nature of this relationship (causal, correlated, consequential) and the mechanisms involved are not fully understood.

The Multifaceted Etiology of Mental Disorders With a Focus on Trace Elements, a Review of Recent Literature

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Mental disorders are a significant global public health concern, affecting nearly one in eight individuals worldwide. This review investigates the multifaceted etiology of mental disorders—specifically major depressive disorder (MDD), schizophrenia (SCZ), and bipolar disorder (BD)—through genetic, neurobiological, and environmental ...
