High-Resolution Integrative Delimitation of Intertidal Limpets via Multi-Locus Barcodes and SEM Morphology

Diversity
Limpets are marine gastropod molluscs well adapted to intertidal rocky environments, yet their taxonomic resolution remains challenging due to extensive morphological convergence and the presence of cryptic species.

Oligosaccharides With Defined Glycosidic Bonds Shape Gut Microbial Succession and Metabolism Via Bond‐Specific Microbial Responders

Advanced Science, EarlyView.
Oligosaccharides with defined glycosidic bonds drive divergent gut microbial succession and shape unique metabolic profiles. Absolute time‐series profiling with Bayesian generalized Lotka–Volterra modeling identifies bond‐specific microbial responders, while monoculture validation and metaproteomics reveal linkage‐matched transport and cleavage modules.

m5C Reader ALYREF Promotes the Progression of Endometrial Cancer by Activating the XRCC6‐Mediated Wnt/β‐catenin Signaling Pathway

Advanced Science, EarlyView.
This study identifies ALYREF as an oncogenic m5C reader in endometrial cancer. ALYREF recognizes NSUN2‐mediated m5C modification on XRCC6 mRNA to enhance transcript stability and increase XRCC6 expression. Elevated XRCC6 activates Wnt/β‐catenin signaling, resulting in accelerated tumor cell proliferation, migration, invasion, and xenograft tumor growth.

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.

Identification and phylogenetic analysis of marine sponges in the Jordanian Gulf of Aqaba using DNA barcoding

Heliyon
Sponges (Porifera) are the largest biomass component of coral reefs benthic fauna among marine organisms and are very morphologically diverse. In the present work, we aimed to identify marine sponges in the Jordanian Gulf of Aqaba using the partial 18S ...

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
