Rapamycin Alleviates Heart Failure Caused by Mitochondrial Dysfunction and SERCA Hypoactivity in Syntaxin 12/13 Deficient Models

open access: yesAdvanced Science, EarlyView.
Rapamycin alleviates heart failure via TFEB and CaMKII pathways in Syntaxin 12/13 deficient models. Stx12 deficiency causes heart failure via impaired iron trafficking to mitochondria, reducing respiratory complexes and sarcoplasmic reticulum Ca2+‐ATPase (SERCA).

Atrial Fibroblasts‐Derived Extracellular Vesicles Exacerbate Atrial Arrhythmogenesis

open access: yesAdvanced Science, EarlyView.
Exosome miR‐224‐5p derived from angiotensin II‐treated atrial fibroblasts creates a substrate for AF by promoting atrial electrical remodeling. Increased exosome miR‐224‐5p enhances AF susceptibility by inhibiting CACNA1c expression and decreasing ICa current of atrial cardiomyocytes.

Heme/NADH Mimics Co‐Decorated Allosteric Capsules for Regulating Oxygen Activation and Upregulating Intracellular Methionine Depletion

open access: yesAdvanced Science, EarlyView.
Through modifying the switchable µ‐oxo bridged FeIII‐porphyrins moiety and NADH mimics into a metal‐organic capsule, multiple responsive manners for O2 activation, chemical oxygenation and metabolic transformation have been demonstrated for upregulating intracellular methionine depletion and accumulation of methionine sulfoxide to achieve effective ...

A Charge‐Adhesive Targeted DNA Gel Bandage for the Precision Treatment of Inflammatory Bowel Disease

open access: yesAdvanced Science, EarlyView.
DNA gel bandage (DNAgb) is designed to precisely target the site of inflammation of IBD, by achieving dual specific localization of inflamed mucosa through electrostatic interactions and ApITGA4‐mediated affinity targeting. DNAgb effectively the activation of inflammatory pathways and reshapes the immune microenvironment.

Communicative Nanomotors Reprogram Cancer Cell Death via Pyroptosis

open access: yesAngewandte Chemie, EarlyView.
Communicative nanomotors respond to elevated ROS in the tumor microenvironment, enabling active communication and selective mitochondrial targeting through non‐covalent surface engineering. Their precise interaction with cells induces mitochondrial damage, cytochrome c release, and pyroptotic cell death, while chemotactic motility ensures deeper tumor ...

Neuronal Endothelin a Receptor Mediates Experimental and Clinical Vascular Pain through an Endothelial‐Neural Axis

open access: yesAdvanced Science, EarlyView.
The authors develop mouse models by mimicking peripheral vascular diseases, combining multiple strategies and transgenic mouse lines, to demonstrate that ECs, but not macrophages or SMCs, play an active role mediated by endothelial ET‐1/neural ETAR signaling and beyond endothelial homeostatic angiocrine by driving protective pain through the ...

Lipocalin‐2 activates hepatic stellate cells and promotes nonalcoholic steatohepatitis in high‐fat diet–fed Ob/Ob mice

open access: yesHepatology, EarlyView., 2022
Graphical summary of obesity‐induced NASH progression by LCN2 targeted to HSC activation. Abstract Background and Aims In obesity and type 2 diabetes mellitus, leptin promotes insulin resistance and contributes to the progression of NASH via activation of hepatic stellate cells (HSCs).

The Iron–Sulfur Cluster of Bacterioferritin‐Associated Ferredoxin (Bfd): a “Biological Fuse” that Prevents Oxidative Damage to Cells?

open access: yesAngewandte Chemie, EarlyView.
When cellular iron is low, bacterioferritin (Bfr) releases its stored iron through a reductive process dependent on the [2Fe–2S] ferredoxin Bfd. Why accessing stored iron should depend on an iron‐requiring protein when iron is scarce is unclear. Here, we show that the Bfd [2Fe–2S] cluster is sensitive to oxidative stress, suggesting that it may act as ...
