A Patient‐Derived Organoid Biobank of Adamantinomatous Craniopharyngioma as a Platform for Drug Discovery

open access: yesAdvanced Science, EarlyView.
This study successfully establishes adamantinomatous craniopharyngioma (ACP) patient‐derived organoids (PDOs) that preserve the histopathological and genetic features of the original tumors. Through drug sensitivity assays and subsequent mechanistic analyses, the study demonstrates that Ceritinib exerts its inhibitory effects on ACP PDO growth by ...

Bisphenol B Exposure Induces Miscarriage by Suppressing Migration/Invasion and Migrasome Formation

open access: yesAdvanced Science, EarlyView.
BPB (Bisphenol B) exposure up‐regulates ER (estrogen receptor) levels, enhances its interactions with the lnc‐HZ04 promoter region, and thus promotes ER‐mediated lnc‐HZ04 transcription. Subsequently, lnc‐HZ04 suppresses TCF4 (transcription factor 4)‐mediated PKCA (protein kinase C alpha) transcription and subsequently suppresses migration/invasion and ...

Construction of a Multitissue Cell Atlas Reveals Cell‐Type‐Specific Regulation of Molecular and Complex Phenotypes in Pigs

open access: yesAdvanced Science, EarlyView.
This research conducts an in‐depth investigation of cell‐type‐specific regulatory mechanisms underlying molecular and complex phenotypes through integrative analysis of multitissue single‐nucleus RNA sequencing, bulk RNA‐seq, and genome‐wide association study (GWAS) data in pigs.

Tie2‐Dependent Mechanisms Influence Leptomeningeal Collateral Dynamics and Reperfusion Following Stroke

open access: yesAdvanced Science, EarlyView.
This work demonstrates that endothelial EphA4 limits Tie2 activation and curbs leptomeningeal collateral expansion after ischemic stroke. Pharmacological activation of Tie2 by an Ang‐1 mimetic or genetic loss of EphA4 stimulates collateral vessel growth, improves cerebral perfusion, and enhances neurological recovery.

TSHR‐Targeting Nucleic Acid Aptamer Treats Graves' Ophthalmopathy via Novel Allosteric Inhibition

open access: yesAdvanced Science, EarlyView.
This study presents YC3, a novel inhibitory TSHR‐targeting aptamer, as a promising therapeutic for Graves' ophthalmopathy (GO). YC3 suppresses pathological phenotypes in human orbital fibroblasts and improves outcomes in GO mice by binding to a previously unidentified allosteric site on TSHR, demonstrating the potential of aptamers in advancing ...

Plant Virus‐Induced Inheritable Apoptosis Drives Reproductive Costs in Female Insect Vectors to Balance Viral Biparental Transmission

open access: yesAdvanced Science, EarlyView.
Rice gall dwarf virus (RGDV), transmitted biparentally by leafhopper vector to their offspring, exploits the capsid protein to induce inheritable ovarian apoptosis via insulin‐driven PI3K/AKT/FoxO signaling axis. This mechanism enhances infection but reduces female reproductive fitness, causing inefficient maternal transmission.

Hyperandrogenemia Induces Trophoblast Ferroptosis and Early Pregnancy Loss in Patients With PCOS via CMA‐Dependent FTH1 Degradation

open access: yesAdvanced Science, EarlyView.
In PCOS patients with hyperandrogenemia, decreased ferritin heavy chain 1 (FTH1) causes Fe2⁺ overload and ferroptosis in trophoblasts. Androgens induce FTH1 protein degradation via AR‐LAMP2A‐mediated chaperone‐mediated autophagy pathway, leading to placental development disruption and early pregnancy loss. Metformin mitigates androgen‐induced placental

Targeting Adipose Tissue Function Protects Against Heart Failure with Preserved Ejection Fraction

open access: yesAdvanced Science, EarlyView.
This study explores the role adipose tissue (AT) phenotypes have in determining cardiovascular outcomes in an obesity‐related heart failure with preserved ejection fraction (HFpEF) model. Pharmacological induction of thermogenesis promoted resilience to HFpEF‐induced remodeling of AT and conferred cardioprotection. Surgical and genetic models confirmed

Structural and Functional Characterization of EXPO‐Derived Extracellular Vesicles in Plants

open access: yesAdvanced Science, EarlyView.
In this study, 3D electron tomography (ET), cryo‐ET, and immunogold transmission electron microscopy (TEM) are employed to characterize plant extracellular vesicles (EVs) under physiological conditions. EVs are classified into three distinct categories according to their size, content, and molecular‐marker profiles. Furthermore, Exo70E2‐positive medium
