TRAIL-induced variation of cell signaling states provides nonheritable resistance to apoptosis. [PDF]

, 2019
TNFα-related apoptosis-inducing ligand (TRAIL), specifically initiates programmed cell death, but often fails to eradicate all cells, making it an ineffective therapy for cancer.

Endocytic Control of Cell‐Autonomous and Non‐Cell‐Autonomous Functions of p53

Advanced Science, EarlyView.
NUMB Ex3‐containing isoforms localize to the plasma membrane, where they recruit p53 through SNX9 and direct it to multivesicular bodies and exosomes. Exported p53 is taken up by neighboring cells and activates nuclear programs, revealing an intercellular, exosome‐based pathway that might help establish a tumor‐suppressive microenvironment.

DCAF13 Safeguards Hematopoietic Stem Cells via RRS1‐Regulated Ribosome Biogenesis

Advanced Science, EarlyView.
This study establishes DCAF13 as an essential regulator for hematopoietic stem cell (HSC) function. Its deletion in mice causes lethal pancytopenia and HSC depletion. Mechanistically, DCAF13 interacts with RRS1 and mediates its non‐degradative K27‐linked ubiquitination, thereby stabilizing RRS1 to maintain ribosome biogenesis and protein translation ...

SLC19A1 transports immunoreactive cyclic dinucleotides. [PDF]

, 2019
The accumulation of DNA in the cytosol serves as a key immunostimulatory signal associated with infections, cancer and genomic damage1,2. Cytosolic DNA triggers immune responses by activating the cyclic GMP-AMP synthase (cGAS)-stimulator of interferon ...

TEAD1 Enhances Exosome Secretion and Promotes Exosome‐Mediated Tissue Regeneration

Advanced Science, EarlyView.
TEAD1 functions as a crucial molecular switch regulating exosome secretion in various cell types. TEAD1 enhances exosome secretion by upregulating key proteins associated with exosome secretion, including RAB11, CD9, and SNAP23. This study reveals a novel role for TEAD1 in regulating exosome secretion and tissue regeneration, particularly in diabetic ...

BGN/MDK Axis in the Melanoma Tumor Microenvironment Strengthens Tumor Malignancy by Modulating Cancer Cells and Cancer‐Associated Fibroblasts Crosstalk

Advanced Science, EarlyView.
This study reveals that m6A regulators cooperatively upregulate BGN in melanoma, promoting malignancy. Within the tumor microenvironment, CAFs show highest BGN expression. The BGN/MDK axis mediates cancer‐stroma crosstalk, driving normal fibroblast (NF) activation and enhancing the pro‐tumor effect of CAFs, highlighting a promising therapeutic target ...

NPM1 Mediates mRNA Sorting into Extracellular Vesicles via Specific RNA Motif Binding and Phase Separation

Advanced Science, EarlyView.
NPM1 selectively sorts specific mRNAs into extracellular vesicles (EVs) by recognizing RNA motifs and forming phase‐separated condensates. These mRNA cargos—including EGFR—are then loaded via multivesicular bodies. This active sorting pathway, validated in EVs derived from both lung cancer cells and patient serum, reveals a specific mechanism for ...

Discovery of SKP2‐Recruiting PROTACs for Target Protein Degradation

Advanced Science, EarlyView.
Based on the SKP2‐targeting ligand SL1, we designed non‐covalent PROTACs by linking it with the BRD4 inhibitor JQ1 and the AR antagonist AL through a linker. These PROTACs successfully induced the ubiquitination of BRD4 and AR, followed by proteasome‐mediated degradation.

Timing Mechanotransduction: Mechanically Dynamic Biomaterials Reveal the Temporal Hierarchy of YAP/TAZ Control Nodes

Advanced Science, EarlyView.
This work develops dynamically softening polyacrylamide hydrogels for time‐resolved imaging during continuous mechanical transitions. The study revealed that mechanotransduction is biphasic; YAP/TAZ inactivation is driven by early loss of the nucleocytoskeletal continuum connecting subnuclear adhesions, F‐actin, and the nuclear envelope, coupled with ...
