Tumbling Magnetic Microrobots for Targeted In Vivo Drug Delivery in the GI Tract
Advanced Robotics Research, EarlyView.We introduce a microrobot design and integrated system for on‐demand targeted drug release in the gastrointestinal tract. The microrobot has an embedded magnet for actuation with external magnetic fields and is visualized in real time using ultrasound. It has two drug release ports sealed with a thermally sensitive wax. Local heating of the wax using a

Chronic Hypoxia Disrupts Spermatogenesis Through ASXL2–EZH2–Mediated Microtubule Destabilization
Advanced Science, EarlyView.This study reveals the mechanism by which chronic hypoxia impairs spermatogenesis via the ASXL2–EZH2 axis, hindering the transition of spermatids from round to elongated forms. Key findings reveal that under hypoxic conditions, downregulated ASXL2 expression reduces EZH2 binding to the CEP162 promoter, leading to decreased H3K27me3 modification and ...

DRD2 Deficiency Underlies Pituitary Adenoma Dependent on Escherichia coli Translocation from the Gut
Advanced Science, EarlyView.Dopamine receptor D2 (DRD2) deficiency disrupts epithelial barrier integrity in both the gut and pituitary gland, facilitating translocation of gut‐derived Escherichia coli into pituitary tissue. Intratumoral E. coli are phagocytosed by microglia, triggering GSDMD‐dependent pyroptosis and HMGB1 release, which subsequently activates MAPK signaling to ...

Advanced Science, EarlyView.Antibody drug conjugates deliver their cytotoxic anti‐tubulin or topoisomerase I inhibitor payloads to tumors through cancer cell receptor targeting. The released drug payloads induce cellular changes that interact with radiotherapy resulting in radiosensitization that improves cancer cell kill and stimulates anti‐tumor immune responses.

Bufalin Inhibits the PI3K/AKT Pathway by Targeting GTF3C4 to Impede Breast Cancer Progression
Advanced Science, EarlyView.Mechanisms of Bufalin‐Mediated Intervention in Breast Cancer. ABSTRACT Breast cancer incidence is rising globally, presenting challenges such as treatment side effects and drug resistance. Bufalin is a bufadienolides compound with potential anti‐cancer effects. This study shows that bufalin inhibits malignant proliferation of MDA‐MB‐231 and MCF‐7 cells
