Expression and Activation of BKCa Channels in Mice Protects Against Ischemia-Reperfusion Injury of Isolated Hearts by Modulating Mitochondrial Function

Frontiers in Cardiovascular Medicine, 2019
Aims: Activation and expression of large conductance calcium and voltage-activated potassium channel (BKCa) by pharmacological agents have been implicated in cardioprotection from ischemia-reperfusion (IR) injury possibly by regulating mitochondrial ...

Opioid-induced Cardioprotection [PDF]

Current Pharmaceutical Design, 2014
Ischemic heart disease and myocardial infarction continue to be leading causes of cardiovascular morbidity and mortality. Activation of opioid, adenosine, bradykinin, adrenergic and other G-protein coupled receptors has been found to be cardioprotective.

Remote Conditioning by Rhythmic Compression of Limbs Ameliorated Myocardial Infarction by Downregulation of Inflammation via A2 Adenosine Receptors

Frontiers in Cardiovascular Medicine, 2022
BackgroundRemote ischemic conditioning (RIC) is a cardioprotective phenomenon, yet transient ischemia is not a requisite trigger for remote cardioprotection.

Microenvironment‐Responsive Nanomedicine Enables Vertical Modulation of Mitochondrial Pathological Networks in Myocardial Ischemia–Reperfusion Injury

Advanced Science, EarlyView.
A mitochondria‐targeted, microenvironment‐responsive nanoplatform enables pH/ROS‐triggered co‐delivery of berberine and isoliensinine to orchestrate ROS scavenging, inflammation suppression, and apoptosis inhibition. This vertical modulation of mitochondrial pathological networks preserves mitochondrial function and effectively mitigates myocardial ...

Impact of Mitochondrial Ca2+-Sensitive Potassium (mBKCa) Channels in Sildenafil-Induced Cardioprotection in Rats.

PLoS ONE, 2015
BackgroundMitochondrial large-conductance Ca2+-sensitive potassium (mBKCa) channels are involved in myocardial ischemic preconditioning. Their role in sildenafil-induced cardioprotection is unknown.

Protective Role of Platelets in Myocardial Infarction and Ischemia/Reperfusion Injury

Cardiology Research and Practice, 2021
Thrombotic occlusion of the coronary artery is a key component in the pathogenesis of myocardial ischemia and myocardial infarction (MI). The standard therapy for ischemia is revascularization and restoration of blood flow to previously ischemic ...

New Aspects for the Treatment of Cardiac Diseases Based on the Diversity of Functional Controls on Cardiac Muscles: Mitochondrial Ion Channels and Cardioprotection

Journal of Pharmacological Sciences, 2009
Mitochondrial ATP-sensitive K+ (mitoKATP) and Ca2+-activated K+ (mitoKCa) channels exist in cardiac myocytes, and they play key roles in cardioprotection.

A Novel Pak1 Activator Ameliorates ER Stress for HFpEF Therapy

Advanced Science, EarlyView.
Chronic metabolic stress is a major contributor to HFpEF progression. Under prolonged metabolic stress, Pak1 activity becomes impaired, contributing to disrupted ER proteostasis, cardiomyocyte apoptosis, fibrosis, and diastolic dysfunction. Mechanistically, Pak1 overexpression activates the ERK1/2–MNK1–eIF4E signaling axis, promotes translational ...

Cardioprotection and its Translation: A Need for New Paradigms? Or for New Pragmatism? An Opinionated Retro- and Perspective

Journal of Cardiovascular Pharmacology and Therapeutics, 2023
The dawn of cardioprotection by infarct size reduction originated from the idea to favourably alter the oxygen demand–supply balance of the ischaemic/infarcting myocardium by reducing the contractile determinants of its oxygen consumption.
