PP2Acα Deficiency in Vascular Smooth Muscle Cells Accelerates Aortic Aneurysm and Dissection by Regulating KLF4 Phosphorylation and Ubiquitination

open access: yesAdvanced Science, EarlyView.
Vascular smooth muscle cells (VSMCs)‐specific deficiency of PP2Acα exacerbates aortic aneurysm and dissection (AAD) by promoting phenotypic switching through AKT1‐mediated phosphorylation and stabilization of Kruppel‐like factor 4 (KLF4). Reduced PP2Acα enhances KLF4 ubiquitination resistance, suppressing VSMC contractile genes and accelerating aortic ...

The GRK2/AP‐1 Signaling Axis Mediates Vascular Endothelial Dysfunction and Atherosclerosis Induced by Oscillatory Low Shear Stress

open access: yesAdvanced Science, EarlyView.
This study highlights GRK2 is a central mediator in OSS‐induced endothelial dysfunction. OSS activates GPCRs in endothelial cells, leading to GRK2 phosphorylation and the activation of AP‐1. AP‐1 induces inflammation, while also promoting NR4A1 expression and anchoring LKB1 in the nucleus, which suppresses AMPK activity. This cascade causes endothelial

Ferrocene‐Functionalized Black Phosphorus Nanoplatform Enables Targeted and Prolonged MRI Visualization of Atherosclerotic Plaques

open access: yesAdvanced Science, EarlyView.
Aminoferrocene is employed to modify black phosphorus, generating stable phosphorus radicals (FcP). The FcP is then functionalized with hyaluronic acid (HA) to produce the HA‐FcP radical complex, thereby developing a novel, highly efficient, sensitive, long‐lasting, and low‐heavy‐metal‐content radical contrast agent for targeted imaging of ...

Dynamic Bonds Reinforced Polyamide Elastomer for Biomedical Orthosis

open access: yesAdvanced Science, EarlyView.
A dynamic bonds (DBs) reinforced shape memory polyamide elastomer is developed using reactive extrusion. Dynamic covalent networks enhance interlayer adhesion in 4D‐printed objects by utilizing the combined effects of multiple DBs, reducing mechanical anisotropy and improving the mechanical and shape memory properties.
