MetabolomicsCEACAM1 Targets ABCA1 to mediate Atrial Fibrillation by regulating Lipophagy-Dependent Ferroptosis

Atrial fibrillation（AF） is one of the most common arrhythmias, imposing a significant burden on individuals due to its association with cerebrovascular events. The mechanisms underlying AF involve cardiac structural remodeling, electrical remodeling, and metabolic remodeling, with oxidative ...

MetabolomicsTargeted metabolomic profiling and machine learning-based prediction models for persistent atrial fibrillation: a multi-center observational study

Background. Atrial fibrillation (AF), the most common cardiac arrhythmia worldwide, carries a high risk of severe complications. Patients diagnosed with paroxysmal atrial fibrillation (PAF) may progress to persistent atrial fibrillation (PerAF) following a period. We aimed to identify metabo...

TranscriptomicsHsp70 protects from stroke in atrial fibrillation patients by preventing thrombosis with no increased bleeding risk
Atrial fibrillation (AF) is a major risk factor for cardioembolic stroke. Anticoagulant drugs are effective in preventing AF-related stroke. However, the high frequency of anticoagulant-associated major bleeding is a major concern particularly when antiplatelet treatment is simultaneously administer...

TranscriptomicsValvular heart disease and atrial fibrillation regulate microRNA expression profiles in left and right atria differently
Background: Chronic atrial fibrillation (AF) is a complication associated with the dilated atria of patients with valvular heart disease and contributes to worsened pathology. Methods and Results: Using microarray technology, we examined microRNA (miR) expression profiles in right and left atrial ap...

TranscriptomicsRac1-Induced Connective Tissue Growth Factor regulates Connexin 43 and N-Cadherin Expression in Atrial Fibrillation
Objectives: We studied the signal transduction of atrial structural remodelling that contributes to the pathogenesis of atrial fibrillation (AF). Backround: Fibrosis is a hallmark of arrhythmogenic structural remodelling but the underlying molecular mechanisms are incompletely understood. Methods: W...

TranscriptomicsAtrial fibrillation is associated with altered left-to-right atria gene expression ratio: implications for arrhythmogenesis and thrombogenesis
Background: Atrial fibrillation (AF) causes atrial remodeling, and the left atrium (LA) is the favored substrate for maintaining AF. However, it remains unclear if AF remodels both atria differently and contributes to LA arrhythmogenesis and thrombogenesis. Results: AF was associated with differenti...

ProteomicsMultiomic analysis of PI3K in Atrial Myopathy
Here, we undertook comprehensive physiological and molecular analyses in cardiac-specific transgenic mice with increased or decreased PI3K to assess the dose response impact of directly regulating PI3K. Elevated PI3K was associated with a dose-dependent increase in heart size, and preserved/enhanced...

ProteomicsTranscriptome and Proteome Mapping in the Sheep Atria Reveal Molecular Features of Atrial Fibrillation Progression
Atrial fibrillation (AF) is often a progressive cardiac arrhythmia that increases the risk of hospitalization and adverse cardiovascular events. There is a clear demand for more inclusive and large-scale approaches to understand the molecular drivers responsible for AF, as well as the fundamental me...

TranscriptomicsGene expression data of postnatal Pitx2 deficient heart
Pitx2 is the homeobox gene located in proximity to the human 4q25 familial atrial fibrillation locus. Pitx2 haploinsufficient mice are prone to pacing induced atrial fibrillation indicating that reduced Pitx2 promotes an arrhythmogenic substrate within the atrium. Here, we inactivated Pitx2 in postn...
