CaMKIIγ advances chronic intermittent hypoxia-induced cardiomyocyte apoptosis via HIF-1 signaling pathway.
Sleep Breath
January 2025
Nantong Key Laboratory of Translational Medicine in Cardiothoracic Diseases, and Research Institution of Translational Medicine in Cardiothoracic Diseases, Affiliated Hospital of Nantong University, Nantong, Jiangsu, 226001, China.
Background: Our previous study have demonstrated chronic intermittent hypoxia (CIH) induced cardiomyocyte apoptosis and cardiac dysfunction. However, the molecular mechanisms are complicated and varied. In this study, we first investigated the CaMKIIγ expression and signaling pathway in the pathogenesis of cardiomyocyte apoptosis after CIH.

Secondhand smoke exposure (SHSe) is a public health threat for people with cystic fibrosis (CF) and other lung diseases. Primary smoking reduces CFTR channel function, the causative defect in CF. We reported that SHSe worsens respiratory and nutritional outcomes in CF by disrupting immune responses and metabolic signaling.

Department of Internal Medicine, Hebei Medical University, Shijiazhuang, Hebei, China.
Background: Heart failure with preserved ejection fraction (HFpEF) represents a challenging cardiovascular condition characterized by normal systolic function but impaired diastolic performance. Despite its increasing prevalence, therapeutic options remain limited. This study investigated the metabolic effects of canagliflozin, a sodium-glucose cotransporter 2 (SGLT2) inhibitor, on cardiac function and energy metabolism in HFpEF.

Department of Cardiology, Liuzhou Workers' Hospital, The Fourth Affiliated Hospital of Guangxi Medical University, Liuzhou, China.
Background: Fibroblasts in the fibrotic heart exhibit a heterogeneous biological behavior. The specific subsets of fibroblasts that contribute to progressive cardiac fibrosis remain unrevealed. Our aim is to identify the heart fibroblast (FB) subsets that most significantly promote fibrosis and the related critical genes as biomarkers for ischemic heart disease.

Department of Cardiology, The Fourth Affiliated Hospital, Nanjing Medical University, Nanjing, China.
Myocardial infarction (MI), a severe cardiovascular disease, is the result of insufficient blood supply to the myocardium. Despite the improvements of conventional therapies, new approaches are needed to improve the outcome post-MI. Imperatorin is a natural compound with multiple pharmacological properties and potential cardioprotective effects.
