Aberrant Splicing Signatures Underpin Oligodendrocyte Damage in ALS and Neuron Loss in FTD

Advanced Science, EarlyView.
Integrating bulk and single‐nucleus RNA‐seq from ALS and FTD patients, we revealed distinct cellular dysfunctions, with severe oligodendrocyte damage in ALS and pronounced neuron loss in FTD. We identified cell‐type‐specific aberrant splicing events as potential biomarkers with robust classification performance, some of which produce de novo peptides ...

Atrophic Skeletal Muscle‐Derived Extracellular Vesicles Transfer miR‐125a‐5p to Inhibit Bone Formation in Osteoporosis during Aging

Advanced Science, EarlyView.
A muscle‐bone endocrine pathway in aging is revealed in which extracellular vesicles released from atrophic skeletal muscle (Aged‐SKM‐EVs) inhibit bone formation. These EVs deliver miR‐125a‐5p to osteoblasts, thereby suppressing the SIRT7‐Sp7 signaling axis and osteogenic differentiation.

An Insulin‐Exosome‐TNFAIP8 Axis Drives Stromal Fibrosis and Therapeutic Resistance in Pancreatic Cancer

Advanced Science, EarlyView.
In pancreatic ductal adenocarcinoma (PDAC), insulin is associated with activation of PI3K/AKT–RAB3A signaling and enhanced secretion of TNFAIP8‐enriched exosomes from tumor cells. Uptake of these exosomes by fibroblasts is linked to TRIM21‐dependent STAT1 degradation and the emergence of myofibroblastic CAF–associated features, accompanied by increased

miR‐185‐5p Derived From hUC‐MSC Exosomes via Suspension Culture Under Hypoxic Conditions Promotes Scarless Wound Healing in Mice by Precisely Regulating Collagen I/III Regeneration

Advanced Science, EarlyView.
miR‐185‐5p derived from UC‐MSC exosomes via hypoxic suspension culture promotes scarless wound healing in mice by precisely regulating collagen I/III regeneration. Exosomes derived from UC‐MSCs under a three‐dimensional bioreactor and hypoxic conditions were injected into the skin wounds of mice.

TOGR3, a Proteasome β4 Subunit, Orchestrates Sugar Homeostasis to Trade Off Growth and Thermotolerance in Rice

Advanced Science, EarlyView.
This study identifies a novel thermoregulatory mechanism in rice: TOGR3 partners with 26S proteasome subunits, including TT1, to drive thermoresponsive ubiquitin–proteasome activity, maintaining sugar homeostasis in stomatal regulation to balance growth and stress resistance.

Identification of A p300–SP1–BRD4 Transcriptional Axis as a Key Driver of AR Hyperactivation in Polycystic Ovarian Syndrome

Advanced Science, EarlyView.
This study reveals a pivotal epigenetic regulatory role for the histone acetyltransferase p300, demonstrating that its acetylation of histone 3 at lysine 18 and 27 (H3K18ac and H3K27ac), alongside the formation of the p300/BRD4/SP1 complex, drives AR activation and ovarian fibrosis in PCOS.

Properties of the Class of Measure Separable Compact Spaces

, 1994
We investigate properties of the class of compact spaces on which every regular Borel measure is separable. This class will be referred to as MS. We discuss some closure properties of MS, and show that some simply defined compact spaces, such as ...

TGFβ1 Activates Lnc‐APUE to Promote Tumor Metastasis via the Alu Element‐Driven STAU1‐Mediated Decay of CDH1 mRNA

Advanced Science, EarlyView.
We delineate a TGFβ1/SMAD/lnc‐APUE/E‐cadherin axis wherein TGFβ1 signaling activates lnc‐APUE; lnc‐APUE subsequently downregulates E‐cadherin expression via Alu element‐driven STAU1‐mediated decay of CDH1 mRNA, thereby promoting tumor metastasis. Our findings reveal a novel regulatory function for lnc‐APUE within the SMD pathway, elucidate a distinct ...

Adipocyte‐Derived Exosomal miR‐5099 Mitigates M1 Macrophage Polarization and Adipose Inflammation via c‐Met/NF‐κB Axis to Improve Metabolic Health

Advanced Science, EarlyView.
Celastrol upregulates adipocyte‐derived exosomal miR‐5099, suppressing the macrophage c‐Met/NF‐κB axis to mitigate pro‐inflammatory M1 polarization and adipose inflammation. These miR‐5099‐enriched exosomes also act as endocrine signals targeting the liver, muscle, and adipocytes to significantly enhance systemic insulin sensitivity.
