Angiopoietin-1 is a vascular strengthening factor during vascular development and a protective factor for pathological vascular inflammation and leakage. Brain vascular leaking and inflammation are two important pathological processes of stroke; therefore, we hypothesized that variants of the microRNA-binding site in angiopoietin-1 would affect its(More)
OBJECTIVE Recent studies have revealed that microRNAs (miRNAs) are involved in the regulation of cardiac development, physiologic, and pathologic processes via post-transcriptional control of gene expression. The stable circulating miRNAs offer unique opportunities for the early diagnosis of several diseases. In this study, we examined the circulating(More)
In this study, we determined the role of PDGF-D, a new member of the PDGF family, in a rat model of balloon injured artery made with a 2F catheter in Sprague-Dawley male rats. PDGF-D expression was studied in the injured and control segments of abdominal aorta. The function of PDGF-D was evaluated in rat vascular smooth muscle cells stably transfected with(More)
Angiopoietin-2 has been reported to regulate the inflammation process, which is associated with recurrence of stroke. The purpose of this study was to test the hypothesis that plasma levels of angiopoietin-2 and variants of angiopoietin-2 will confer risk of stroke recurrence. The association of plasma angiopoietin-2 (determined by using ELISA) and the(More)
Aminoglycosides promote the readthrough of premature stop codons introduced by nonsense mutations to produce full-length proteins in genetic disease models. The read-through effects of different aminoglycosides and PTC124 on HERG gene have yet to be adequately elucidated. The wild-type (WT) or mutant genes were transiently transfected in HEK293 cells. The(More)
AIMS Clinical and animal studies suggest that beta1-adrenergic and M2 muscarinic receptor autoantibodies (beta1-AAbs and M2-AAbs) play important roles in the pathophysiological process of chronic heart failure (CHF). Removal of these autoantibodies improved haemodynamic parameters and left ventricular ejection fraction patients with CHF. The goal of this(More)
BACKGROUND Recent studies suggest that variants in two calcium handling genes (RyR2 and CASQ2) associated with sudden cardiac death (SCD) and non-sudden cardiac death (NSCD) in subjects with heart failure and coronary artery disease, respectively. The purpose of this study was to identify other calcium handling genes associated with SCD in the long-term of(More)
AIMS To investigate the relationship between electrocardiogram (ECG) parameters [J wave, fragmented QRS (fQRS), QTc, the peak-to-end interval of T wave (Tp-Te)], and sudden cardiac death (SCD) in chronic heart failure (CHF). METHODS AND RESULTS The ECGs of 1570 CHF patients, 572 cases with dilated cardiomyopathy (DCM) and 998 cases with ischaemic(More)
The genetic background of early repolarization syndrome (ERS) has not been fully understood. In this study, we identified a missense SCN5A mutation and a polymorphism in a patient with ERS and characterized the functional consequences of the two variants. The functional consequences of mutant channels were investigated with the patch-clamp technique,(More)
Type III collagen plays an important role in activating platelets, forming thrombus, and maintaining the mechanical properties of arteries. This study aimed to test the hypothesis that genetic variants of COL3A1 (gene encoding type III collagen) contribute to recurrence and prognosis of stroke. We investigated the associations of three variants (rs2138533,(More)
