- High cholesterol is a key cardiovascular risk factor that can modulate cardiac electrophysiology and promote acquired long QT syndrome (acLQTS)-related cardiotoxicity, a potentially life-threatening condition associated with QT prolongation, torsade de pointes, and sudden cardiac death. This study investigated the effects of cholesterol overload on human Ether-à-go-go-Related Gene (hERG/Kv11.1; encoded by KCNH2) potassium channels and L-type calcium channels (LTCC; mainly Cav1.2/CACNA1C in cardiomyocytes), as well as the underlying mechanisms of acLQTS-related cardiotoxicity, using human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs), whole-cell patch clamp, quantitative real-time PCR (qRT-PCR), Western blotting, immunoprecipitation, fluorescence imaging, and a high-cholesterol diet guinea pig model with rosuvastatin intervention combined with optical mapping. The results showed that transient cholesterol exposure inhibited hERG tail current amplitude and accelerated channel inactivation, with the effect showing a Y652-dependent component, while also enhancing LTCC activity. Mechanistically, cholesterol overload triggered endoplasmic reticulum (ER) stress, impaired hERG proteostasis, and promoted ER-to-lysosome-associated degradation (ERLAD) of hERG. This process was associated with CANX-mediated recognition of abnormal hERG and FAM134B-LC3B-related autophagic-lysosomal processing, contributing to reduced total hERG expression and membrane-localized mature hERG. FAM134B overexpression partially preserved hERG expression and attenuated cholesterol-induced ER stress/autophagy-related abnormalities. In vivo, rosuvastatin improved lipid profiles and cardiac remodeling in high-cholesterol guinea pigs but was associated with more pronounced action potential duration (APD) and QT interval prolongation under high-cholesterol conditions. These findings suggest that cholesterol overload may increase susceptibility to hERG-related repolarization abnormalities during rosuvastatin exposure and highlight the importance of cholesterol management and electrocardiographic (ECG) monitoring in hypercholesterolemic settings. - Source: PubMed

Deng KunhongGuo YanZhang YaxinQiu HuiKuang YunWang YuMeng DiZhang MengGuo Chengxian - CACNA1C-related disorder (CRD), a severe multisystem disorder caused by variants of gene, presents significant diagnostic and management challenges due to its rarity and variable expressivity. This study leverages a detailed longitudinal case report and comprehensive literature review to expand the phenotypic spectrum of CRD with Timothy syndrome (TS) features associated with the NM_001129830.1: c.3061 T > C (p.Cys1021Arg) variant. We describe an individual with CRD exhibiting a severe multisystem phenotype including classic features like syndactyly, profound neurological symptoms, and cardiac arrhythmias. Critically, our detailed clinical and genetic analysis identified previously undocumented features for this specific variant: cerebral infarction, as well as a combined T-cell and B-cell immunodeficiency characterized by specific lymphocyte dysregulation. These novel findings necessitate refined diagnostic protocols and tailored management strategies. By redefining CRD with TS features as a profoundly multisystem disorder, this expanded understanding facilitates improved prognostication, genetic counseling, and targeted therapeutic interventions, aiming to transform management from unpredictable complications into predictable, preventable components, ultimately enhancing quality of life and survival. - Source: PubMed
