Single‐Molecule Characterization of Bacterial Factor‐Dependent Transcription Activation by Rob

open access: yesAdvanced Science, EarlyView.
Factor‐dependent transcription activation is crucial and involves complex interactions between transcription factors, RNA polymerase, and promoter DNA. Using single‐molecule assays, we show that Rob prebinds RNAP to facilitate promoter search and enhances DNA unwinding and promoter escape.

Multi‐tissue Metabolic GWAS and Drought‐Responsive Multi‐omics Reveal the Genetic Basis of the Quinoa Metabolome

open access: yesAdvanced Science, EarlyView.
A multi‐omics framework combining multitissue genome‐wide association studies, metabolomics, transcriptomics, proteomics, and functional validation uncovers the genetic basis of specialized metabolism in quinoa. The study identifies hundreds of metabolite‐associated loci, prioritizes candidate genes for saponin, betalain, and flavonoid biosynthesis ...

Histidine and carnosine alleviated hepatic steatosis in mice consumed high saturated fat diet

open access: yes, 2012
[[abstract]]The effects of histidine, alanine and carnosine on activity and/or mRNA expression of lipogenic enzymes and sterol regulatory element-binding proteins (SREBPs) in liver and adipose tissue from high fat diet treated mice were examined ...

An Efficient Detection Platform Based on Mesoporous Au@Cr2O3 Particles with Schwarz P Surface for Precise Periodontitis Metabolite Profiling

open access: yesAdvanced Science, EarlyView.
A non‐invasive periodontitis diagnosis platform was developed using Au nanoparticles‐decorated mesoporous Cr2O3 (Au@mCr2O3) particles with Schwarz P surface as matrix for saliva metabolic fingerprinting (SMFs) analysis via MALDI‐MS. With the assistance of machine learning of SMFs, this platform enables efficient diagnosis and the screening of potential

Design and Engineering of an Artificial Bifunctional N‐Deacetylase/N‐Sulfotransferase for the Biosynthesis of N‐Sulfated Heparosan

open access: yesAdvanced Science, EarlyView.
An artificial bifunctional N‐deacetylase/N‐sulfotransferase was engineered in Escherichia coli by combining screened N‐deacetylases with an NST domain. The integrated engineering strategy improved enzyme performance. The optimized enzyme efficiently converted heparosan into N‐sulfated heparosan, addressing a key bottleneck in microbial heparin ...

TRAF6 Lactylation in Glycolytic Macrophages Drives NF‐κB Signaling and M1 Polarization During Orthodontic Tooth Movement

open access: yesAdvanced Science, EarlyView.
Schematic diagram showing compressive stress triggers glycolytic reprogramming and lactate accumulation in macrophages. Lactate mediates TRAF6 lactylation at K171/K180 dual sites, which enhances its K63‐linked ubiquitination to activate the NF‑κB pathway and promote M1 polarization. This cascade drives orthodontic tooth movement (OTM) and alveolar bone

Co-localization of Histamine and eGFP in the Central Nervous System from pHdc-5’-UTR-eGFP Transformants of Drosophila melanogaster [PDF]

open access: yes, 2009
Histamine is a biogenic amine synthesized by the enzyme histidine decarboxylase (Hdc) and used as a neurotransmitter in the central nervous system of Drosophila melanogaster.

Coordination‐Tuned Iridium Single‐Atom Nanozymes Boost Multienzyme Activity for Colorimetric Sensing

open access: yesAdvanced Science, EarlyView.
Breaking the coordination symmetry of Ir single‐atom sites through asymmetric Ir–N3S1 engineering tailors interfacial electron transfer, oxygen activation, and multienzyme‐like catalytic pathways. Operando spectroscopy and theoretical modeling uncover the atomic‐level origin of activity enhancement, providing a strategy for designing multifunctional ...
