The literature provides abundant evidence that mesenchymal stem cells (MSCs) are an attractive resource for therapeutics and have beneficial effects in regenerating injured tissues due to their self-renewal ability and broad differentiation potential. Although the therapeutic potential of MSCs has been proven in both preclinical and clinical studies,(More)
Mesenchymal stem cells (MSCs) have therapeutic potential for the repair of myocardial injury. The efficacy of MSC therapy for myocardial regeneration mainly depends on the survival of cells after transplantation into the infarcted heart. In the transplanted regions, reactive oxygen species (ROS) can cause cell death, and this process depends on caspase(More)
PURPOSE Thiazolidinediones (TZDs) are known to inhibit the proliferation of vascular smooth muscle cell (VSMC) by increasing the activity of p27Kip1 and retinoblastoma protein (RB). However, the upstream signaling mechanisms associated with this pathway have not been elucidated. The Akt-mTOR-P70S6 kinase pathway is the central regulator of cell growth and(More)
Cardiac Ca2+ cycling and signaling are closely associated with cardiac function. Changes in cellular Ca2+ homeostasis may lead to aberrant cardiac rhythm and may play a critical role in the pathogenesis of cardiac diseases, due to their exacerbation of heart failure. MicroRNAs (miRNAs) play a key role in the regulation of gene expression at the(More)
Aging is a multidimensional process that leads to an increased risk of developing severe diseases, such as cancer and cardiovascular, neurodegenerative, and immunological diseases. Recently, small non-coding RNAs known as microRNAs (miRNAs) have been shown to regulate gene expression, which contributes to many physiological and pathophysiological processes(More)
Atrial fibrillation (AF) has been recognized as a major cause of cardiovascular-related morbidity and mortality. MicroRNAs (miRNAs) represent recent additions to the collection of biomolecules involved in arrhythmogenesis. Reactive oxygen species (ROS) have been independently linked to both AF and miRNA regulation. However, no attempts have been made to(More)
The inhibition of insulin-stimulated proliferation of vascular smooth muscle cells by rosiglitazone is mediated by the Akt-mTOR-P70S6K pathway. Purpose: Thiazolidinediones (TZDs) are known to inhibit the proliferation of vascular smooth muscle cell (VSMC) by increasing the activity of p27 Kip1 and retinoblastoma protein (RB). However, the upstream signaling(More)
Pyroptosis is the most recently identified type of regulated cell death with inflammatory response and has characteristics distinct from those of apoptosis or necrosis. Recently, independent studies have reported that small noncoding RNAs termed microRNAs (miRNAs) are involved in the regulation of pyroptosis. Nevertheless, only a handful of empirical data(More)
Pathological stress including myocardial infarction and hypertension causes a negative effect on calcium regulation and homeostasis. Nevertheless, few studies reveal that Ca2+ regulatory genes are related to pathological status in cardiomyocytes under early hypoxia. To determine the alteration of Ca2+-related gene in hypoxic myocytes, primary neonatal rat(More)
