Ascites circRNA ASCOR Drives Platinum Resistance of High‐Grade Serous Ovarian Cancer by Facilitating RPA1 Nuclear Translocation

open access: yesAdvanced Science, EarlyView.
High‐grade serous ovarian carcinoma (HGSOC) is plagued by platinum resistance, with malignant ascites closely linked to poor outcomes. Here, we identify ASCOR, a circRNA enriched in ascites small extracellular vesicles (sEVs) from platinum‐resistant HGSOC patients, as a predictor of poor survival. ASCOR enhances platinum resistance in vitro and in vivo

TP53 R249S mutation in hepatic organoids captures the predisposing cancer risk

open access: yesHepatology, EarlyView., 2022
The systematic approach in elucidating the gain‐of‐function (GOF) roles of TP53 mutations in early liver carcinogenesis. Unique downstream targets of TP53 L3 mutations were identified from chormatin immunoprecipitation sequencing in HCC cell lines, followed by a series of validation assays to substantiate the exclusive transcriptional regulations ...

Pro‐ATO/Allicin Liposomes for Dual‐Pathway Targeting of p53‐Mutant Tumors

open access: yesAdvanced Science, EarlyView.
Schematic illustration of the “pro‐ATO”/allicin liposomal strategy. Liposomal encapsulation improves the stability and bioavailability of both agents while masking allicin's odor. Upon release in the tumor microenvironment, ATO reactivates structural p53 mutants, and allicin inhibits ATR signaling while releasing H2S, collectively inducing synthetic ...

Elevated TRIM25 Impairs Poly (ADP‐ribose) Metabolism via PARG Degradation and Mediates Compression‐Induced Intervertebral Disc Degeneration

open access: yesAdvanced Science, EarlyView.
TRIM25 acts as a multifunctional hub driving intervertebral disc degeneration under mechanical stress. Mechanical compression significantly upregulates TRIM25 expression, establishing it as a key E3 ubiquitin ligase platform. TRIM25 targets PARG and Ku80 via distinct molecular interfaces, triggering their ubiquitination and degradation.

Engineering MnPt Bimetallic Nanozymes for Cascade Enzymatic Therapy and Enhanced Radio‐Immunotherapy

open access: yesAdvanced Science, EarlyView.
A CD44‐targeted MnPt bimetallic nanozyme (HD@MnO2) integrates multienzyme‐like activity with cGAS–STING activation to boost radio‐immunotherapy. Through cascade biocatalysis, it depletes glutathione, relieves hypoxia, and amplifies ROS, enhancing radiotherapy‐induced DNA damage and immunogenic cell death. The nanozyme promotes dendritic cell maturation

Integrative Approaches to Treating Cellular Senescence in Kidney Disease

open access: yesAdvanced Science, EarlyView.
ABSTRACT Cellular senescence in the kidney plays a crucial role in the progression of acute kidney injury and chronic kidney disease. Therapeutic approaches targeting senescent cells, such as small molecule senolytic and senomorphic drugs, display efficacy in preclinical models.

CD3ɛ Nanobody‐Engineered Extracellular Vesicles Driving In Vivo Generation of TCE‐secreting CAR‐Ts for Solid Tumor Therapy With Memory Response and Minimal Immunogenicity

open access: yesAdvanced Science, EarlyView.
HEK‐293T‐derived CD3ε Nb‐engineered EVs to generate dual‐targeting CAR‐T cells directly in vivo. These EVs selectively deliver CAR.BiTE transgenes into T cells and reprogramed to HLA‐G/PD‐L1‐targeting effector cells with enhanced memory and persistence.

The influence of organic solvents on estimates of genotoxicity and antigenotoxicity in the SOS chromotest

open access: yesGenetics and Molecular Biology, 2012
In this work, the toxicity and genotoxicity of organic solvents (acetone, carbon tetrachloride, dichloromethane, dimethylsulfoxide, ethanol, ether and methanol) were studied using the SOS chromotest.

CRISPR‐Cas9‐Loaded Theranostic Liposomes for Enhancing Radiosensitization of Prostate Cancer through POLD4 Gene Editing under Real‐Time MRI Monitoring

open access: yesAdvanced Science, EarlyView.
This study identifies POLD4 as a potential prostate cancer radiosensitization target through transcriptome sequencing. By encapsulating POLD4‐targeted CRISPR/Cas9 plasmids and USPIONs in cationic liposomes, an MRI‐monitored gene‐editing platform is established.

Glutamine Deprivation Triggers Tribbles Homolog 3 Dependent G‐Quadruplex Resolution to Maintain DNA Repair and Tumor Survival

open access: yesAdvanced Science, EarlyView.
Glutamine deprivation triggers transient DNA damage yet activates adaptive repair in hepatocellular carcinoma cells. We identify TRIB3 as a stress‐induced nuclear scaffold that associates with DDX5 and G‐quadruplex DNA atBRCA1 andRAD51AP1 promoters. TRIB3 loss increases G4 accumulation, suppresses HR gene transcription, elevates γ‐H2A.X, and sensitizes
