hESCs‐derived Organoids Achieve Liver Zonation Features through LSEC Modulation

Advanced Science, EarlyView.
This article addresses the absence of zonation features in current organoid models by co‐culturing human embryonic stem cell‐derived hepatocytes with liver sinusoidal endothelial cells exhibiting distinct zonal characteristics. It demonstrates that differential WNT2 signaling from endothelial cells modulates hepatocyte zonation and metabolic functions,

Epileptiform Activity and Seizure Risk Follow Long‐Term Non‐Linear Attractor Dynamics

Advanced Science, EarlyView.
This study leverages the HAVOK framework to model long‐term, nonlinear attractor dynamics underlying epileptiform activity and seizure risk in epilepsy patients. By identifying key forcing mechanisms driving chaotic transitions, the findings improve seizure risk forecasting over multi‐day cycles and provide a pathway for personalized, data‐driven ...

The Novel Dual GIP and GLP‐1 Receptor Agonist Tirzepatide Attenuates Colon Cancer Development by Regulating Glucose Metabolism

Advanced Science, EarlyView.
Tirzepatide, a dual GIP/GLP‐1 receptor agonist for diabetes, suppresses colorectal cancer growth by targeting glucose metabolism. It inhibits cancer cell proliferation, promotes apoptosis, and induces tumor regression. It reduces glucose uptake and destabilizes HIF‐1α for degradation to downregulate PFKFB3/PFK‐1 enzymes, thus contributing to the ...

P21‐Activated Kinase 2 as a Novel Target for Ventricular Tachyarrhythmias Associated with Cardiac Adrenergic Stress and Hypertrophy

Advanced Science, EarlyView.
Ca2+/calmodulin‐dependent kinase II (CaMKII) activation is likely driven by oxidative stress, particularly excessive reactive oxygen species (ROS) production. This study identifies P21‐activated kinase 2 (Pak2) as a novel regulator of ROS‐induced CaMKII activation and abnormal Ca2⁺ dynamics in acute adrenergic and chronic pressure‐overload stressed ...
