AIMS Fractalkine (FKN) is a newly identified membrane-bound chemokine; its role in myocardial ischaemia and heart failure is largely unknown. We attempted to investigate the role of FKN in myocardial ischaemia and ischaemia or pressure overload-induced ventricular remodelling and heart failure. METHODS AND RESULTS FKN-induced changes of heart(More)
OBJECTIVES To test the hypothesis that resveratrol would improve cardiac remodeling by inhibiting the detrimental effects of fractalkine. We previously reported that fractalkine exacerbates heart failure. Furthermore, this study sought to determine whether resveratrol targets fractalkine to improve myocardial ischemia and cardiac remodeling. DESIGN(More)
BACKGROUND Transient preceding brief ischemia provides potent cardioprotection against subsequent long ischemia, termed ischemic preconditioning. Here, we hypothesized that transient short-term hypertrophic stimulation would induce the expression of hypertrophy regression genes and render the heart resistant to subsequent hypertrophic stress, and slow the(More)
AIMS We investigated the influence of type one cannabinoid receptor (CB1) deficiency on acute heart failure (AHF) and the underlying mechanism. Acute heart failure syndrome is an important clinical problem because of its high morbidity and mortality rates. Activation of CB1 induces vascular dilation and reinforces the properties of morphine, long-standing(More)
AIMS Targeted point mutants of hypoxia-inducible factor-1α (HIF-1α) are potential optimal agents for angiogenesis therapy. Data are limited regarding the angiogenic response of HIF-1α mutants. We aimed to compare the angiogenic effect of wild-type and mutant HIF-1α by contrast ultrasound molecular imaging (UMI) of α(v)-integrin expression. METHODS AND(More)
This study was aimed to investigate whether the antihypertrophic effects of adiponectin in murine hearts are associated with the modulation of HB-EGF signaling. We determined the myocardial expressions of adiponectin and adiponectin receptors, brain natriuretic peptide (BNP), and HB-EGF in normal and hypertrophied hearts of adiponectin knockout mice or(More)
AIMS in this study, we attempted to detect a recent myocardial ischaemic event using ultrasound molecular imaging (UMI) with microbubbles (MB) targeted to intercellular adhesion molecule-1 (ICAM-1) in the late phase of reperfusion. METHODS AND RESULTS we created a myocardial ischaemia-reperfusion model in 60 C57/BL male mice to simulate an angina attack(More)
The gene ankyrin repeat domain 1 (Ankrd1) is an enigmatic gene and may exert pleiotropic function dependent on its expression level, subcellular localization and even types of pathological stress, but it remains unclear how these factors influence the fate of cardiomyocytes. Here we attempted to investigate the role of CARP on cardiomyocyte hypertrophy. In(More)
Fibroblast growth factor 23 (FGF23) has been reported to induce left ventricular hypertrophy, but it remains unclear whether FGF23 plays a role in cardiac fibrosis. This study is attempted to investigate the role of FGF23 in post-infarct myocardial fibrosis in mice. We noted that myocardial and plasma FGF23 and FGF receptor 4 were increased in mice with(More)
