Cold Orthogonal Translation: A Psychrophilic Pyrrolysyl‐tRNA Synthetase Boosts Genetic Code Expansion in E. coli

Advanced Science, EarlyView.
ABSTRACT Orthogonal translation systems (OTSs) enable site‐specific incorporation of non‐canonical amino acids (ncAAs) and are central to genetic code expansion. Current engineering strategies typically rely on hyperstable aminoacyl tRNA synthetase (aaRS) scaffolds to tolerate destabilizing mutations required for substrate diversification.

Understanding and Overcoming Antibody‐Drug Conjugate Resistance: Biological Mechanisms and Emerging Analytical Frameworks in Breast Cancer

Advanced Science, EarlyView.
Antibody–drug conjugates (ADCs) transform breast cancer therapy, yet resistance limits their durability. Emerging evidence reveals that ADC failure is not solely tumor‐intrinsic but shaped by dynamic tumor–microenvironment interactions that alter drug delivery, processing, and response.

Mechanostimulatory Cues Determine Intestinal Fibroblast Fate and Profibrotic Remodeling in a Physiodynamic Human Gut‐on‐a‐Chip

Advanced Science, EarlyView.
A healthy gut barrier shields underlying fibroblasts from luminal shear forces, illustrating that “good fences make good neighbors.” Barrier damage exposes fibroblasts to shear stress, inducing cell death and the emergence of stress‐adapted, profibrotic fibroblasts. Sustained shear exposure promotes the formation of stiff aggregates of mechanoadapative

PRC2.1 Coordinates Peri‐Nucleolar H3K27me3‐Enriched Heterochromatin Organization and NPM1 Pentamerization to Maintain Nucleolar Integrity

Advanced Science, EarlyView.
PRC2.1(PCL2)‐coordinated H3K27me3‐enriched PNH establishes a spatial scaffold crucial for nucleolar integrity. As a crucial coordinator, PCL2 links PRC2.1 to chromatin organization and NPM1 assembly. This network‐based model reveals how chromatin modifications and nucleolar components cooperatively maintain nucleolar architecture, revealing novel ...

Extracellular Vesicle‐Transferred ATP‐Citrate Lyase Induces Monocyte Differentiation Toward Tumor‐Associated Macrophages and Fuels Hepatocellular Carcinoma Progression

Advanced Science, EarlyView.
Hepatocellular carcinoma (HCC)‐derived extracellular vesicles (EVs) enrich the metabolic enzyme ATP‐citrate lyase (ACLY). EV‐transferred ACLY enhances palmitate biosynthesis, increases the S‐palmitoylation and stability of multiple immune checkpoint proteins, augments the cellular immunosuppressive activity, and ultimately accelerates the malignant ...

Nanomedicine Meets Immunotherapy: Advancing Adoptive Cell Therapy with Nanoparticles in the Treatment of Cancer with Sustainability Perspectives

Advanced Science, EarlyView.
This review surveys nanoparticle‐based strategies to enhance adoptive cell therapy, particularly CAR‐T cell approaches, in solid tumor treatment. It describes how nanoparticles can improve tumor immunogenicity and T‐cell infiltration while reducing toxicity, and how they enable in vivo CAR‐T cell generation.

Tumor‐Induced Splenic Remodeling: Mechanisms of Systemic Immunosuppression and Emerging Therapeutic Opportunities

Advanced Science, EarlyView.
ABSTRACT Despite the transformative impact of cancer immunotherapies such as immune checkpoint blockade, durable clinical responses remain limited. Increasing evidence indicates that antitumor immunity is governed not only by the tumor microenvironment, but also by systemic immune regulation mediated by peripheral immune organs. Among these, the spleen

Enhanced Intracellular Stability and Translation Efficiency of mRNA Drugs by a 2‐arm mRNA Platform

Advanced Science, EarlyView.
We constructed a 2‐arm mRNA, characterized by a unique topology formed through the dimerization of two mRNA 3’ tails. The 2‐arm mRNA improves 3’ tail stability and resistance to nuclease degradation, resulting in an intracellular half‐life of up to 65 h. This method substantially enhances the translation capacity of mRNA drugs.
