Lactate Activates the HCAR1/β‐Arrestin2/PP2A Signaling Axis to Mediate STAT1/2 Dephosphorylation and Drive Osteosarcoma Progression

open access: yesAdvanced Science, EarlyView.
In the present study, it is found that in osteosarcoma, lactate‐activated HCAR1 promotes β‐arrestin 2 translocation from cytoplasm to nucleus. In the nucleus, β‐arrestin 2 recruits PP2A to the activated STAT1/2 dimers, mediating STAT1/2 dephosphorylation and inhibiting the transcription of downstream anti‐oncogenes to promote OS progression.

Adenylosuccinate Synthase 1 Deficiency Improves Energy Metabolism by Promoting Adipose Tissue Re‐esterification via Glycerol Kinase Upregulation

open access: yesAdvanced Science, EarlyView.
Working model of Adss1‐mediated regulation of energy metabolism in adipose tissue. In beige adipocytes, Adss1 interacts with HDAC3 in the cytoplasm, and its loss reduces nuclear HDAC3 while increasing cytosolic fractions. This redistribution suppresses HDAC activity and enhances H3K27 acetylation at the Gk promoter, leading to transcriptional ...

Tumor‐Derived CDC37 Inhibits Antigen Cross‐Presentation in Dendritic Cells and Impairs Anti‐Tumor Immunity in Breast Cancer

open access: yesAdvanced Science, EarlyView.
Extracellular vesicle (EV)‐packaged CDC37 are released from TMBhiCTLlo breast cancer cells with high CDC37 expression, and internalized into endo/phagosomes of dendritic cells (DCs). Within these compartments, CDC37 locked HSP90–antigen complex, preventing antigen release into the cytosol.

FMO2 Promotes Angiogenesis via Regulation of N‐Acetylornithine

open access: yesAdvanced Science, EarlyView.
This study identifies flavin‐containing monooxygenase 2 (FMO2) as a novel proangiogenic regulator in endothelial cells. Targeted FMO2 ablation impairs vessel sprouting, whereas its compensation potently enhances angiogenesis. Metabolomics and single‐cell sequencing reveal that FMO2 drives vascular growth via the N‐acetylornithine/ATF3/NOTCH1 axis ...

Organoid Modeling of Mouse Anterior Tongue Epithelium Reveals Regional and Cellular Identities

open access: yesAdvanced Science, EarlyView.
The tongue's anterior epithelium is maintained by region‐specific stem/progenitor cells, yet in vitro models are limited. Long‐term expanding organoids are developed from adult mouse anterior tongue that retain region‐specific identity, cellular diversity, and gene regulatory features. These organoids differentiate into keratinocytes, Merkel‐like cells,

Nociceptive Nerve‐Derived CGRP Exacerbates Uterine Fibrogenesis in Adenomyosis by Promoting CD140b+ CD146+ Fibroblast Differentiation

open access: yesAdvanced Science, EarlyView.
This study investigates adenomyosis fibrosis in relation to nociceptive nerves. Nociceptive nerve‐secreted CGRP promotes RAMP1hi CD140b+ CD146+ fibroblast differentiation into myofibroblasts through ERK activation, causing severe fibrosis. Rimegepant‐induced CGRP/RAMP1 signaling blockade alleviates fibrosis and restores fertility in a mouse model. This

Tailoring Vascular‐Immune Homeostasis via Manganese‐DNA Complex‐Armed Immunogenic Extracellular Vesicles for Pancreatic Cancer Immunotherapy

open access: yesAdvanced Science, EarlyView.
This study demonstrates that Mn2⁺–tumor DNA complexes encapsulated in dendritic cell (DC)– derived immunogenic extracellular vesicles (EVDC@Mn‐DNA) act as a DC‐specific cGAS– STING activator. EVDC@Mn‐DNA treatment enhances intratumoral DC activation, improves tumor vascular function, promotes CD8⁺ T cell activity, and suppresses pancreatic tumor growth,
