A moderate inflammation caused by the deterioration of housing conditions modifies Trp metabolism but not Trp requirement for growth of post-weaned piglets

Animal, 2010
Deterioration of the environment in which piglets are housed after weaning induces a moderate inflammatory response and modifies tryptophan (Trp) metabolism that can, in turn, decrease Trp availability for growth.

Nuciferine Suppresses Inflammatory Hepatocarcinogenesis by Targeting cPLA2‐Dependent Arachidonic Acid Metabolism

Advanced Science, EarlyView.
Nuciferine directly binds the C2 domain of cPLA2, impairing its Ca2+‐dependent membrane translocation and activation. By suppressing arachidonic acid release and downstream pro‐inflammatory eicosanoid production, nuciferine attenuates NF‐κB signaling and inflammatory hepatocarcinogenesis, revealing cPLA2 as a direct molecular target underlying its ...

Molecular Details of RNA Interactions With FUS Condensates Altering Assembly, Dynamics, and Aggregation

Angewandte Chemie, EarlyView.
Using NMR and molecular simulations, we map how RNA engages FUS LC‐RGG1 within condensates through electrostatic, π‐stacking, and polar contacts. These multivalent RNA contacts help stabilize RNA within FUS condensates while also reshaping condensate composition and dynamics.

Binding Mode between Trp-Dy(III) Complex and Herring Sperm DNA

, 2009
By means of UV and fluorescence spectra, the binding ratios between Dy(III)(Trp)(3) and DNA. in physiological pH environment(pH7.40) were determined as n(Dy(III)(Trp)),:n(DNA) = 2:1 and n(Dy(III)):n(Trp)=1:3.

Donor‐Cell Senescence Redirects PINK1‐Marked Mitochondrial Cargo From Mitophagy to Microvesicle Transfer Through SUMO3‐Stabilized HSPA9

Advanced Science, EarlyView.
ABSTRACT Extracellular vesicle therapies have been developed for tissue repair, but how donor‐cell senescence reshapes vesicle‐mediated mitochondrial transfer remains unclear. Here, we show that senescent adipose‐derived stem cells (ADSCs) redirect damaged mitochondria into microvesicles (MVs), converting protective vesicles into pro‐degenerative ...

Stabilizing Functional Nucleic Acids for Real‐Sample Diagnostics

Angewandte Chemie, EarlyView.
Functional nucleic acids enable programmable real‐sample diagnostics, but often lose function in complex biological matrices. This review highlights four stabilization levers—chemical, topological, architectural, and microenvironment/interface engineering—that preserve aptamer and DNAzyme performance in saliva, serum, urine, and stool, reframing ...

Large Oncosomes Induce Pro‐Metastatic Stromal‐Myeloid Reprogramming

Advanced Science, EarlyView.
Large oncosomes systemically reprogram bone marrow mesenchymal stem cells through innate nucleic acid sensing, driving inflammatory and immunosuppressive remodeling that supports a metastasis‐permissive bone marrow environment, revealing a novel tumor‐host communication axis in cancer. ABSTRACT Bone metastasis can be facilitated by systemic remodeling,

3′‐UTR Hypermethylation and ABA Signaling Coordinate Transcriptional Activation of SWEET14 for High Sugar Accumulation in Citrus

Advanced Science, EarlyView.
Hypermethylation of CliSWEET14 3′‐UTR relieves ClibHLH105‐mediated transcriptional repression, together with ABA signaling‐mediated activation of the CliABF3‐CliNAC56 cascade, boosts CliSWEET14 expression and sucrose accumulation in citrus. ABSTRACT Sugar accumulation is pivotal for fruit quality, yet the molecular regulation of this process remains ...

Switching ATP‐Forming Phosphoryl‐Transfer Chemistry With a Restricted Set of Amino Acids

Angewandte Chemie, EarlyView.
Constraints on amino acid composition relevant to prebiotic chemistry reshape enzyme chemistry by replacing the canonical mechanism within a conserved protein fold with a distinct ATP‐forming reaction, ADP disproportionation. Such constraints generate alternative catalytic solutions not observed in modern enzymes and point to chemically plausible early
