S100A14 in Tumor‐Derived EVs Targets PIAS3 to Reprogram Astrocytes and Induce Immunosuppressive Microenvironment Promoting Brain Metastasis and Germacrone Reversal Effect

Advanced Science, EarlyView.
This study identifies S100A14 in tumor‐derived exosomes as a key driver of brain metastasis. S100A14 targets PIAS3 in astrocytes, activating STAT3 signaling and promoting immunosuppressive MDSCs recruitment via chemokine secretion. Germacrone, a natural compound, binds S100A14 to disrupt this axis, effectively inhibiting brain metastasis with low ...

Engineering the β-galactosidase from Aspergillus oryzae for making lactose-free and no-sugar-added yogurt

Journal of Dairy Science
: Yogurt usually contains 5% to 7% sugar and 3% to 5% lactose. As β-galactosidases can hydrolyze lactose and improve sweetness, they have the potential to produce lactose-free (LF) and no-sugar-added (NSA) yogurt.

Senomorphic Small Extracellular Vesicles Delivered by a Tissue‐Adhesive α‐Lipoic‐Acid Hydrogel Enable Immuno‐Rejuvenation for Bone‐Tendon Interface Regeneration

Advanced Science, EarlyView.
This work identifies M1 macrophage‐mediated inflammation as a key driver of BMSC senescence and bone microstructural deterioration at the enthesis. A tissue‐adhesive hydrogel delivering senomorphic small extracellular vesicles suppresses this inflammatory‐senescent cascade and enhances BMSC resilience by inhibiting the cGAS‐STING‐NF‐κB pathway.

PRMT5/Sohlh2/Sirt1 Signaling Pathway in Vascular Endothelial Cells Modulates Lung Metastasis of Triple‐Negative Breast Cancer

Advanced Science, EarlyView.
The cover image shows that vascular endothelial cells play an important role in lung metastasis of TNBC. Endothelial Sohlh2 acts as a gatekeeper against TNBC lung metastasis by limiting endothelial activation and tumor cell passage. PRMT5 reduces Sohlh2 stability, weakening this protective barrier.

SETD1A Regulates Glycolysis and Senescence of Nucleus Pulposus Cells via H3K4me3–HELZ2/PPARα‐HIF1α Axis to Drive Intervertebral Disc Degeneration

Advanced Science, EarlyView.
SETD1A is a key epigenetic regulator in NPCs during IDD. In normal NPCs, it sustains H3K4me3–HELZ2/PPARα–HIF1α signaling to maintain glycolytic energy metabolism and proliferation. In degenerated NPCs, reduced SETD1A disrupts this axis, impairing glycolysis and accelerating senescence, highlighting a promising therapeutic target for IDD.

Down-Regulation of PpBGAL10 and PpBGAL16 Delays Fruit Softening in Peach by Reducing Polygalacturonase and Pectin Methylesterase Activity

Frontiers in Plant Science, 2018
β-galactosidases are cell wall hydrolases that play an important role in fruit softening. However, PpBGALs mechanism impacting on ethylene-dependent peach fruit softening was still unclear.

Light‐Switched Mesenchymal Stem Cells for In Situ Exosome Amplification in Craniofacial Bone Defect Reconstruction

Advanced Science, EarlyView.
Light‐switchable MSCs (MSC‐UCNPs) were constructed by intracellular incorporation of UCNPs. Upon 980 nm irradiation, UCNPs emitted localized ultraviolet light (365 nm), activating the ROS/HEXB/LAMP1 signaling pathway to suppress lysosome–multivesicular body fusion and thereby enhance exosome biogenesis. Embedded within an injectable hydrogel, MSC‐UCNPs
