tRF‐5004b Enriched Secretory Autophagosomes Induce Endothelial Cell Activation to Drive Acute Respiratory Distress Syndrome

Advanced Science, EarlyView.
Acute respiratory distress syndrome (ARDS) is a severe lung condition with limited treatments, often triggered by overactive endothelial cells (ECs). It is identified that macrophage‐derived secretory autophagosomes (MSAPs) exacerbate lung damage by activating EC function.

Solid‐State NMR Reveals Reorganization of the Aspergillus fumigatus Cell Wall Due to a Host‐Defence Peptide

Angewandte Chemie, EarlyView.
Understanding the mode of action is critical to develop new antifungal drugs. Solid‐state NMR was used to study the reorganization of the Aspergillus fumigatus cell wall by a host‐defence peptide. We identified specific polysaccharides and amino acids that are affected by the peptide.

Effects of Interaction of Leucine and Valine on Growth, Body Wall Amino Acids Composition, and Digestive Ability of Sea Cucumber Apostichopus japonicus

Progress in Fishery Sciences
Branched chain amino acids (BCAAs) are neutral amino acids containing branched aliphatic chains on the α-carbon, including leucine (Leu), isoleucine, and valine (Val), accounting for 18%–20% of the total amino acids in animal and plant proteins.

Valine Requirement for Reproduction in Swine

Journal of Animal Science, 1983
Five levels of L-valine [3.3 (basal), 5.5, 7.8, 10.1 and 12.4 g/d] were fed to gilts from one estrus before mating through two pregnancies and for 30 d of a third pregnancy. Five litter-mate outcome groups of five animals each were allocated randomly to the diet treatments. Animals were individually fed 1.82 kg/d premating and during pregnancy.

A Dual‐Targeting T6SS DNase Drives Bacterial Antagonism and Eukaryotic Apoptosis via the cGAS‐STING‐TNF Axis

Advanced Science, EarlyView.
The bacterial Type VI secretion system (T6SS) emerges as a sophisticated virulence mechanism, leveraging the dual‐function effector TkeA from Yersinia pseudotuberculosis. TkeA concurrently damages rival bacteria and host cell DNA, triggering the host's cGAS‐STING‐TNF pathway and inducing apoptosis.

Backbone Protecting Groups for Enhanced Peptide and Protein Synthesis

Angewandte Chemie, EarlyView.
This review provides a comprehensive account of the use of backbone N‐protecting groups in peptide synthesis. It includes detailed synthetic methods relating to their introduction and removal and their application to “difficult” peptides and proteins of biological significance in both academic and industry contexts.

Zinc Alleviates Gut Barrier Dysfunction by Promoting the Methylation of AKT

Advanced Science, EarlyView.
Zinc activates the ZNG1‐METAP1 complex to elevate intracellular SAM levels, which promotes PRMT5‐mediated symmetrical dimethylation of AKT at R391 and R15. This epigenetic modification facilitates AKT membrane translocation and mTORC2 activation, thereby enhancing epithelial proliferation and gut barrier integrity.

Uptake of branched-chain alpha-keto acids in \u3ci\u3eBacillus subtilis\u3c/i\u3e [PDF]

, 1976
Bacillus subtilis has a constitutive system for the uptake of alpha-keto-beta-methylvalerate, alpha-ketoisovalerate, and (probably) alpha-ketoisocaproate.

Artificial Internalizing Receptors for Targeted Degradation of Extracellular Proteins

Advanced Science, EarlyView.
Small organic molecules that are anchored into the lipid bilayer of a mammalian cell and have an exofacial recognition ligand can act as artificial internalizing receptors. These receptors are an efficacious tool to selectively capture and internalize cognate antibodies from the extracellular environment in a protein‐specific manner.
