A Novel Pak1 Activator Ameliorates ER Stress for HFpEF Therapy

Advanced Science, EarlyView.
Chronic metabolic stress is a major contributor to HFpEF progression. Under prolonged metabolic stress, Pak1 activity becomes impaired, contributing to disrupted ER proteostasis, cardiomyocyte apoptosis, fibrosis, and diastolic dysfunction. Mechanistically, Pak1 overexpression activates the ERK1/2–MNK1–eIF4E signaling axis, promotes translational ...

CD11b+CD43hiLy6Clo splenocyte‐derived macrophages exacerbate liver fibrosis via spleen–liver axis

Hepatology, EarlyView., 2022
A population of splenic monocytes migrate into the liver and shift to macrophages, which account for the exacerbation of liver fibrosis. Abstract Background and Aims Monocyte‐derived macrophages (MoMFs), a dominant population of hepatic macrophages under inflammation, play a crucial role in liver fibrosis progression.

Cardiac Fibrosis in Patients With Atrial Fibrillation

Journal of the American College of Cardiology, 2015
Atrial fibrillation (AF) is associated with structural, electrical, and contractile remodeling of the atria. Development and progression of atrial fibrosis is the hallmark of structural remodeling in AF and is considered the substrate for AF perpetuation. In contrast, experimental and clinical data on the effect of ventricular fibrotic processes in the

Phase Separation of TRIM21 Modulates PTPN14 Stability to Drive Flow‐Dependent Endothelial Activation and Atherogenesis

Advanced Science, EarlyView.
Disturbed flow promotes the formation of TRIM21‐rich biomolecular droplets, which concentrate TRIM21 and PTPN14 and facilitate their SPRY‐FERM interaction (illustrated by the TRIM21 D355‐PTPN14 R132 salt bridge). This condensate‐driven proximity enables TRIM21 to catalyze K48‐linked polyubiquitination of PTPN14 at lysine 956, leading to proteasome ...

Chinese Expert Consensus on the Clinical Application of Finerenone in Geriatric Comorbidities

AGING MEDICINE, EarlyView.
Mineralocorticoid receptor (MR) overactivation drives inflammation, oxidative stress, and fibrosis in the heart, kidneys, and vasculature, leading to cardiorenal dysfunction. MR signaling promotes hypertrophy, remodeling, and injury through pathways like oxidative stress and inflammation, resulting in vascular stiffness and progressive organ damage ...

Lymphatic Abnormalities in Noonan Syndrome Extend Beyond Clinically Apparent Disease

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Lymphatic disease represents a well‐described manifestation of Noonan syndrome (NS), yet the full phenotypic spectrum remains incompletely characterized, especially in asymptomatic individuals. We conducted a cross‐sectional study including 10 individuals with NS (four with peripheral lymphedema and six without) and 10 age‐ and sex‐matched ...

Genotype–Phenotype Correlations of Monoallelic PFIC Variants in Pediatric Liver Disease: A Multicenter Retrospective Cohort Study

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Progressive familial intrahepatic cholestasis (PFIC) is classically caused by biallelic pathogenic variants, yet monoallelic variants of uncertain significance (VUS) in PFIC‐associated genes are increasingly identified in children with cholestasis, creating diagnostic uncertainty.

Molecular and Cellular Mechanisms of Atrial Fibrosis in Atrial Fibrillation

JACC: Clinical Electrophysiology, 2017
Atrial fibrillation (AF) is the most common arrhythmia in clinical practice. Atrial fibrosis has emerged as an important pathophysiological contributor and has been linked to AF recurrences, resistance to therapy and complications. Here, the author reviews the molecular and cellular mechanisms that control atrial fibrosis.

Spectrum of Congenital Anomalies in Myhre Syndrome—Insights Into Effects Brought by Altered TGF‐β Signaling via Gain‐of‐Function Variants in SMAD4

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Myhre syndrome is a rare genetic disorder characterized by progressive multisystem involvement. Gain‐of‐function missense heterozygous variants affecting the Ile500 residue and Arg496 residue of the SMAD4 gene are implicated in this condition.
