The Cytoplasmic MicroRNA‐Production Complex Regulates MicroRNA Sorting to Extracellular Vesicles During Synaptogenesis

Advanced Science, EarlyView.
The mechanisms of microRNA cargo sorting to extracellular vesicles, important mediators of cell communication, are not fully understood. This study reveals that the microRNA‐production machinery acts as a ‘hub’ for the sorting of microRNAs to extracellular vesicles, a process regulated by dynamic organelle interactions.

Photoactivated Platinum Complexes: Targeting Membrane Proteins and Organelles for Precision Cancer Therapy

Angewandte Chemie, EarlyView.
This review highlights an emerging anticancer approach integrating platinum agents into photodynamic therapy (PDT) and photoactivated chemotherapy (PACT) systems, further augmented by cancer cell membrane‐ and organelle‐targeting. By directing photoactivated platinum complexes from nontargeted distribution to cancer cells or defined subcellular sites ...

Decoding Biomolecular Phase Separation: From Physiological Roles to Pathological Mechanisms and Therapeutic Biomaterials Design

Advanced Science, EarlyView.
This review systematically elaborates on the mechanisms underlying physiological regulation and pathological dysregulation of biomolecular phase separation. It also summarizes advances in phase‑separation‑targeted therapeutic strategies and the design of functional biomaterials inspired by this process.

RNA Organelles in DNA‐Based Artificial Cells Provide Spatial Aptamer Functions and Enhanced Signal Processing

Angewandte Chemie, EarlyView.
Multiphase DNA–RNA artificial cells integrate a protective DNA shell, a transcriptionally active DNA core, and a functional RNA organelle. Spatial compartmentalization enables signal generation, external protein expression, and selective recapture via RNA aptamers. ABSTRACT Naturally occurring biomolecular condensates orchestrate key cellular processes

Coronaviral nsp6 hijacks ERAD machinery to facilitate lipolysis and supply membrane components for DMV growth

Nature Communications
The positive-strand RNA ( + RNA) viruses extensively remodel cellular endomembranes to facilitate viral replication, with coronaviruses forming a specialized viral replication organelle (RO) known as double-membrane vesicles (DMVs).

Epithelial SLC25A20 Deficiency Drives Immunosuppressive Neutrophil Remodeling via ARG1 Palmitoylation to Promote Colorectal Cancer

Advanced Science, EarlyView.
SLC25A20 deficiency in tumor cells compromises mitochondrial LCFA transport, which suppresses FAO and drives compensatory release of palmitic acid‐enriched lipids into the TME. These tumor‐derived palmitic acids are taken up by TANs, promoting ZDHHC18‐catalyzed ARG1 palmitoylation.

Cellular Mechanisms Enabling Mitochondria Transfer and Transplantation

Advanced Science, EarlyView.
Mitochondrial transfer and transplantation (mitoTT) is examined as a multistep process governed by distinct transfer routes and post‐transfer checkpoints. Mechanisms controlling mitochondrial uptake, network integration, cristae remodeling, mtDNA maintenance, immune sensing, and quality control are highlighted, revealing key biological and ...

A new player in the biogenesis of lysosome-related organelles

Journal of Cell Biology
How are Rab GTPases regulated during lysosome-related organelle (LRO) biogenesis? Li et al. (https://doi.org/10.1083/jcb.202402016) identify LYSMD proteins as crucial activators of Rab32-family GTPases in LRO development, shedding light on the previously ambiguous mechanisms governing Rab functionality in this process.
