Considerable attention has focused on the role of protein kinase C (PKC) in triggering the profound infarct-sparing effect of ischemic preconditioning (PC). In contrast, the involvement of inositol 1,4,5-trisphosphate [Ins(1,4,5)P(3)], the second messenger generated in parallel with the
Pretreatment with D-myo-inositol-1,4,5-trisphosphate hexasodium (D-myo-IP(3)), the sodium salt of the second messenger inositol 1,4,5-trisphosphate (IP(3)), is cardioprotective and triggers a reduction of infarct size comparable in magnitude to that obtained with ischemic preconditioning. However,
Prophylactic treatment with D-myo-inositol 1,4,5-trisphosphate hexasodium [D-myo-Ins(1,4,5)P3], the sodium salt of the endogenous second messenger Ins(1,4,5)P3, triggers a reduction of infarct size comparable in magnitude to that seen with ischemic preconditioning (PC). However, the mechanisms
5-Diphosphoinositol pentakisphosphate (IP7), formed by a family of inositol hexakisphosphate kinases (IP6Ks), has been demonstrated to be a physiologic inhibitor of Akt. IP6K inhibition may increase Akt activation in mesenchymal stem cells (MSCs), resulting in enhanced cardiac protective effect
Endoplasmic reticulum (ER) stress is increasingly recognized as an important causal factor of many diseases. Targeting ER stress has now emerged as a new therapeutic strategy for treating cardiovascular diseases. Here, we investigated the effects and underlying mechanism of ginkgolide K
In this study, we prepared cordycepin-enriched (CE)-WIB801C, a n-butanol extract of Cordyceps militaris-hypha, and investigated the effect of CE-WIB801C on collagen-induced human platelet aggregation. CE-WIB801C dose-dependently inhibited collagen-induced platelet aggregation, and its IC50 value was
The Mas receptor is a class I G-protein-coupled receptor that is expressed in brain, testis, heart, and kidney. The intracellular signaling pathways activated downstream of Mas are still largely unknown. In the present study, we examined the expression pattern and signaling of Mas in the heart and
BACKGROUND
Cerebral atrophy after stroke is associated with poor functional outcome. The prediction and prevention of post-stroke brain atrophy could therefore represent a target for neurorestorative therapies. We investigated the associations between peri-infarct metabolite concentrations measured
To determine whether cardioprotection after chronic angiotensin II (Ang II) type 1 (AT(1)) receptor blockade involves Ang II type 2 (AT(2)) receptor expression and protein kinase C-epsilon (PKC(epsilon)) activation, we measured in vivo haemodynamics and left ventricular (LV) remodelling and
To determine whether angiotensin II (Ang II) type 2 (AT2)-receptor activation associated with cardioprotection induced by Ang II type 1 (AT1)-receptor blockade during ischaemia-reperfusion (IR) might be reflected in increased AT 2-receptor, IP3-(1,4,5- inositol trisphosphate type 2) receptor and
To determine the metabolic adaptations to compensated heart failure using a reproducible model of myocardial infarction and an unbiased metabolic screen. To address the limitations in sample availability and model variability observed in preclinical and clinical metabolic BACKGROUND
Large transmural myocardial infarction (MI) leads to maladaptive cardiac remodeling and places patients at increased risk of congestive heart failure. Angiotensin II, endothelin, and alpha1-adrenergic receptor agonists are implicated in the development of cardiac hypertrophy, interstitial
Treatments to improve the neurological outcome of edema and cerebral ischemic stroke are severely limited. Here, we present the first in vivo single cell images of cortical mouse astrocytes documenting the impact of single vessel photothrombosis on cytotoxic edema and cerebral infarcts. The volume
The article describes the impact of weight training, micro-elements and vitamins on rehabilitation in post-myocardial infarction patients. Cardiac rehabilitation is a multi-disciplinary and multi-faceted intervention aimed at restoring well-being and retarding disease progression in patients with
