BACKGROUND Caveolins (Cav) are structural proteins that insert into the plasma membrane to form caveolae that can bind molecules important in cardiac signal transduction and function. Cytochrome P450 epoxygenases can metabolize arachidonic acid to epoxyeicosatrienoic acids (EETs) which have known cardioprotective effects. Subsequent metabolism of EETs by(More)
1-(7-Azabenzobicyclo[2.2.1]heptane)diazen-1-ium-1,2-diolate (16) was designed with the expectation that it would act as a dual nitric oxide (NO) and nitroxyl (HNO) donor that is not carcinogenic or genotoxic. Compound 16, with a suitable half-life (17.8 min) in PBS at pH 7, released NO (19%) and HNO (22%) during a 2h incubation in PBS at pH 7. In addition,(More)
Atrial fibrillation (AF) is the most common supraventricular arrhythmia that, for unknown reasons, is linked to intense endurance exercise. Our studies reveal that 6 weeks of swimming or treadmill exercise improves heart pump function and reduces heart-rates. Exercise also increases vulnerability to AF in association with inflammation, fibrosis, increased(More)
To examine the role of oral Ganoderma spore oil in cardiovascular disease, we used transverse aortic constriction (TAC) in mice to model pressure overload-induced cardiomyopathy. Our preliminary results demonstrated a potential cardioprotective role for spore oil extracted from Ganoderma. We found that Ganoderma treatment normalized ejection fraction and(More)
In mice, myocardial hypertrophic preconditioning (HP), which is produced by the removal of short-term transverse aortic constriction (TAC), was recently reported to render the heart resistant to hypertrophic responses induced by subsequent reconstriction (Re-TAC). However, there is no efficient noninvasive method for ensuring that the repeated aortic(More)
As central nodes in cardiomyocyte signaling, nuclear AKT appears to play a cardio-protective role in cardiovascular disease. Here we describe a circular RNA, circ-Amotl1 that is highly expressed in neonatal human cardiac tissue, and potentiates AKT-enhanced cardiomyocyte survival. We hypothesize that circ-Amotl1 binds to PDK1 and AKT1, leading to AKT1(More)
