Copy Number Gains of VPS72 Drive De Novo Lipogenesis and Hepatocarcinogenesis via ATF3/mTORC1/SREBP1 Axis

open access: yesAdvanced Science, EarlyView.
VPS72 overexpression activates mTORC1 signaling, subsequently promoting lipid synthesis and driving HCC progression. VPS72 modulates the epigenetic landscape of ATF3 promoter, such as H2A.Z acetylation reduction and DNA methylation increase, which results in ATF3 repression and subsequent activation of mTORC1.

From Invaginating Site to Deep Lesion: Spatial Transcriptomics Unravels Ectopic Endometrial Penetration Features in Adenomyosis

open access: yesAdvanced Science, EarlyView.
This work utilizes spatial transcriptomics to map the transcriptional landscape of adenomyosis with obvious invagination structure from the invaginating site to deep lesions. By integrating with single‐cell RNA sequencing, this study elucidates the molecular features of invagination, invasion, and fibrosis, and finds the major participants and vital ...

Tumoroid Model Reveals Synergistic Impairment of Metabolism by Iron Chelators and Temozolomide in Chemo‐Resistant Patient‐derived Glioblastoma Cells

open access: yesAdvanced Science, EarlyView.
This study investigates the metabolic vulnerabilities of glioblastoma (GBM), an aggressive brain tumor. Research demonstrates that iron chelation therapy, in combination with standard chemotherapy, significantly enhances the efficacy of treatment against resistant GBM cells in a 3D tumoroid model.

SIRT4 Promotes Pancreatic Cancer Stemness by Enhancing Histone Lactylation and Epigenetic Reprogramming Stimulated by Calcium Signaling

open access: yesAdvanced Science, EarlyView.
As a downstream target of α2δ1‐mediated calcium signaling, SIRT4 serves as an oncogene to promote the stemness of pancreatic cancer via deacetylating ENO1 directly at K358, leading to attenuated ENO1's RNA‐binding capacity, enhanced glycolytic substrate 2‐PG binding and robust glycolytic activity to increase the level of lactate that induce histone ...

Targeting Senescence with Apigenin Improves Chemotherapeutic Efficacy and Ameliorates Age‐Related Conditions in Mice

open access: yesAdvanced Science, EarlyView.
As a plant‐derived flavonoid, apigenin directly targets PRDX6 to inhibit its PLA2 activity, blocking HSPA8 activation and disturbing its interactions with ATM and p38MAPK in senescent cells. By dampening wide spectrum expression of the SASP, apigenin prevents loss of tissue homeostasis, improves organ function, and alleviates multiple age‐related ...

A Compound Screen Based on Isogenic hESC‐Derived β Cell Reveals an Inhibitor Targeting ZnT8‐Mediated Zinc Transportation to Protect Pancreatic β Cell from Stress‐Induced Cell Death

open access: yesAdvanced Science, EarlyView.
Pancreatic β cell loss by cellular stress contributes to diabetes pathogenesis. The study demonstrates that WFS1–ZnT8–zinc axis regulates vicious cycle of zinc transportation and cellular stress in pancreatic β cell. Based on that, the study applies a strategy for compound screening targeting ZnT8 based on human models, and identifies anisomycin, as a ...

Targeting COPA to Enhance Erdafitinib Sensitivity in FGFR‐Altered Bladder Cancer

open access: yesAdvanced Science, EarlyView.
Coatomer protein complex subunit α facilitates the transport of the cargo protein LRPPRC across the Golgi complex and enhances its stability, thereby increasing LRPPRC expression; LRPPRC promotes the stability of ID3 mRNA in an m6A‐dependent manner, thereby decreasing the transcriptional activity of p16 and p21, which leads to increased erdafitinib ...

Protease‐Mediated Synthesis of Zein Nanofibrils: From Structural Elucidation to Functional Application

open access: yesAdvanced Science, EarlyView.
The globular shape and hydrophobicity of zein made it unsuitable to be processed in pure aqueous environment. Pepsin‐mediated hydrolysis converts zein into water‐soluble and fibril‐forming peptides with a bioconversion rate exceeding 70%, enabling the self‐assembly of amyloid‐like nanofibrils.

Development of Carbon‐11 Labeled Pyrimidine Derivatives as Novel Positron Emission Tomography (PET) Agents Enabling Brain Sigma‐1 Receptor Imaging

open access: yesAdvanced Science, EarlyView.
Novel carbon‐11 labeled pyrimidine derivatives are developed as PET imaging probes for visualizing sigma‐1 receptors in the brain. [11C]CNY‐01 demonstrates superior brain uptake and binding specificity in both rodents and non‐human primates. The study reveals decreased sigma‐1 receptor expression in Alzheimer's disease, offering a promising tool for ...

Inhibiting the Histone Demethylase Kdm4a Restrains Cardiac Fibrosis After Myocardial Infarction by Promoting Autophagy in Premature Senescent Fibroblasts

open access: yesAdvanced Science, EarlyView.
Kdm4a downregulation restrains excessive cardiac interstitial fibrosis and remodeling by depressing the premature senescence of fibroblasts in the advanced stage after MI but does not affect early ventricular rupture. It verified that Kdm4a downregulation promotes autophagy in premature senescent fibroblasts by increasing the H3K9m3 modification of the
