Functional–Taxonomic Scaling Resolves Conflicting Average Genome Size Estimates Across Environmental Gradients

Advanced Science, EarlyView.
Based on genome size‐functional breadth theory, we introduce and validate a framework that adjudicates conflicting average genome size (AGS) estimates by testing which estimate yields a gap between scaled functional diversity and scaled taxonomic diversity that is consistent with the expected positive association between genome size and gene functional

Chronic Stress Promotes Gastric Cancer Metastasis by Inducing Microbiota‐Associated Kynurenine Accumulation and Macrophage Remodeling

Advanced Science, EarlyView.
Chronic stress reshapes the gut microbiota and enriches Lactobacillus reuteri, promoting microbiota‐associated kynurenine accumulation through altered tryptophan metabolism. Kynurenine drives immunosuppressive remodeling of tumor‐associated macrophages through TNFR2–C/EBPβ signaling, thereby enhancing gastric cancer dissemination.

Phylogenetic diversity of sediment bacteria from the deep Northeastern Pacific Ocean: a comparison with the deep Eastern Mediterranean Sea

, 2010
The variability of bacterial community composition and diversity was studied by comparative analysis of five 16S rRNA gene clone libraries from deep-sea sediments (water column depth: 4000 m) of the Northeastern Pacific Ocean and Eastern Mediterranean ...

Hierarchical Flux‐Protection Engineering Stabilizes Oxidation‐Prone Metabolic Nodes for High‐Level Curcumin Biosynthesis

Advanced Science, EarlyView.
Flux‐protection engineering stabilizes an oxidation‐prone L‐DOPA node in engineered E. coli by combining acid‐adapted chassis evolution, respiratory‐chain modulation, enzyme‐level flux matching, and pH–DO control. Carbon is redirected from oxidative browning to productive biosynthesis, enabling 1075.2 mg/L curcumin and demonstrating transferability to ...

Ultrasound‐Activated Nanoinhibitors Blocking the Chemo‐Immune Checkpoint to Overcome Chemotherapy‐Induced Immune Resistance

Advanced Science, EarlyView.
A sono‐responsive chemo‐immune checkpoint nanoinhibitor (Sono‐TT8) co‐delivering TPZ chemotherapy and siXkr8 simultaneously kills tumor cells and blocks PS externalization, reversing chemotherapy‐induced immunosuppression and enhancing antitumor immunity. ABSTRACT Breast cancer features an immunosuppressive tumor microenvironment following chemotherapy
