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)
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)
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)
BACKGROUND Pharmacologic restoration of the trafficking defects of HERG missense mutations has been documented. However, whether correction of HERG nonsense mutations is possible is unknown. OBJECTIVE The purpose of this study was to investigate the effect of aminoglycoside antibiotics on the expression of nonsense mutants expected to produce truncated(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)
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)
Intracranial aneurysms (IAs) are acquired lesions in the brain and can pose potential risk of rupture leading to subarachnoid hemorrhage. Endoglin plays a pivotal role in the vascular development and disease. Variations of endoglin gene have been shown to be risk factors for IAs in different racial population. In the present study, we investigated the(More)
OBJECT Variants of Kallikreins have been shown to be risk factors for intracranial aneurysm (IA) in a Finnish population. In the present study, the authors investigated the correlation between polymorphisms in the Kallikrein gene cluster and IAs in the Chinese population. METHODS The association of Kallikrein variants (rs1722561 and rs1701946) with(More)
