Chaperone Mediated Autophagy Protects Cardiomyocytes Against Hypoxic-Cell Death
This study for the first time establishes a protective role for CMA (via Lamp2a overexpression) against hypoxia-induced cardiomyocyte loss and reveals the intriguing possibility that CMA activation may offer a cardioprotective treatment for ischemic heart disease.PMID:35584327 | DOI:10.1152/ajpcell.00369.2021

Galanin Regulates Myocardial Mitochondrial ROS Homeostasis and Hypertrophic Remodeling Through GalR2
The regulatory peptide galanin is broadly distributed in the central nervous systems and peripheral tissues where it modulates numerous physiological and pathological processes through binding to its three G-protein-coupled receptors, GalR1-3. However, the function and identity of the galaninergic system in the heart remain unclear. Therefore, we investigated the expression of the galanin receptors in cardiac cells and tissues and found that GalR2 is the dominant receptor subtype in adult mouse hearts, cardiomyocytes and H9C2 cardiomyoblasts. In vivo, genetic suppression of GalR2 promotes cardiac hypertrophy, fibrosis and ...

Salvianolic Acid B Suppresses ER Stress-Induced NLRP3 Inflammasome and Pyroptosis via the AMPK/FoxO4 and Syndecan-4/Rac1 Signaling Pathways in Human Endothelial Progenitor Cells
Oxid Med Cell Longev. 2022 Mar 17;2022:8332825. doi: 10.1155/2022/8332825. eCollection 2022.ABSTRACTMounting evidence demonstrates uncontrolled endoplasmic reticulum (ER) stress responses can activate the inflammasome, which generally results in endothelial dysfunction, a major pathogenetic factor of chronic inflammatory diseases such as atherosclerosis. Salvianolic acid B (SalB), produced by Radix Salviae, exerts antioxidative and anti-inflammatory activities in multiple cell types. However, SalB's effects on ER stress-related inflammasome and endothelial dysfunction remain unknown. Here, we showed SalB substantially abro...

Overexpression of the Hsa21 Transcription Factor RUNX1 Modulates the Extracellular Matrix in Trisomy 21 Cells
Down syndrome is a neurodevelopmental disorder frequently characterized by other developmental defects, such as congenital heart disease. Analysis of gene expression profiles of hearts from trisomic fetuses have shown upregulation of extracellular matrix (ECM) genes. The aim of this work was to identify genes on chromosome 21 potentially responsible for the upregulation of ECM genes and to pinpoint any functional consequences of this upregulation. By gene set enrichment analysis of public data sets, we identified the transcription factor RUNX1, which maps to chromosome 21, as a possible candidate for regulation of ECM gene...

Using computational methods to design patient-specific electrospun cardiac patches for pediatric heart failure
Biomaterials. 2022 Feb 18;283:121421. doi: 10.1016/j.biomaterials.2022.121421. Online ahead of print.ABSTRACTAutologous cardiac cell therapy is a promising treatment for combating the right ventricular heart failure (RVHF) that can occur in patients with congenital heart disease (CHD). However, autologous cell therapies suffer from low cell retention following injection and patient-to-patient variability in cell quality. Here, we demonstrate how computational methods can be used to identify mechanisms of cardiac-derived c-Kit+ cell (CPC) reparative capacity and how biomaterials can be designed to improve cardiac patch perf...

Interference with the expression of S1PR1 or STAT3 attenuates valvular damage due to rheumatic heart disease
Int J Mol Med. 2021 Sep;48(3):179. doi: 10.3892/ijmm.2021.5012. Epub 2021 Jul 23.ABSTRACTRheumatic heart disease (RHD) affects numerous individuals annually; however, its pathogenesis remains unclear. The sphingosine 1‑phosphate receptor 1 (S1PR1) and signal transducer and activator of transcription 3 (STAT3) have recently been shown to be involved in valvular damage via the promotion of the differentiation of T helper 17 (Th17) cells during the development of RHD‑induced valvular damage. The present study investigated whether altering the expression of S1PR1 or STAT3 attenuates valvular damage due to RHD. Inactivated ...
