Glimepiride, a novel sulfonylurea, does not abolish myocardial protection afforded by either ischemic preconditioning or diazoxide [PDF]

open access: yes, 2001
Background: The sulfonylurea glibenclamide (Glib) abolishes the cardioprotective effect of ischemic preconditioning (IP), presumably by inhibiting mitochondrial KATP channel opening in myocytes. Glimepiride (Glim) is a new sulfonylurea reported to affect

HIF1α-dependent mitophagy facilitates cardiomyoblast differentiation [PDF]

open access: yes, 2020
Mitophagy is thought to play a key role in eliminating damaged mitochondria, with diseases such as cancer and neurodegeneration exhibiting defects in this process.

Doxorubicin‐Loaded Metal–Organic Framework for Ferroptosis‐Enhanced Chemotherapy Through Sustained Zn Release and Glutathione Peroxidase Downregulation

open access: yesAdvanced Healthcare Materials, EarlyView.
A robust zinc‐based metal–organic framework (ZnMOF) enables dual functions of doxorubicin delivery and sustained Zn2+ release to trigger ferroptosis‐enhnaced chemotherapy. DOX@ZnMOF effectively depletes intracellular glutathione, suppresses GPX4, and elevates reactive oxygen species, leading to efficient oxidative DNA damage and apoptosis.

Reversible Blockade of Complex I or Inhibition of PKCβ Reduces Activation and Mitochondria Translocation of p66\u3csup\u3eShc\u3c/sup\u3e to Preserve Cardiac Function after Ischemia [PDF]

open access: yes, 2014
Aim Excess mitochondrial reactive oxygen species (mROS) play a vital role in cardiac ischemia reperfusion (IR) injury. P66Shc, a splice variant of the ShcA adaptor protein family, enhances mROS production by oxidizing reduced cytochrome c to yield H2O2 ...

Bioenergetics Consequences of Mitochondrial Transplantation in Cardiomyocytes. [PDF]

open access: yes, 2020
Background Mitochondrial transplantation has been recently explored for treatment of very ill cardiac patients. However, little is known about the intracellular consequences of mitochondrial transplantation.

Patient‐Derived 3D Bioprinted Cardiac Organoid Constructs Reveal Key Pathological Features of Duchenne Muscular Dystrophy

open access: yesAdvanced Healthcare Materials, EarlyView.
Patient‐derived cardiac organoids reveal key features of Duchenne muscular dystrophy cardiomyopathy, including apoptosis, oxidative stress, calcium handling defects, and mechanical remodeling. By integrating organoids into alginate–gelatin bioprinted constructs, disease phenotypes are organized into scalable 3D cardiac tissues displaying extracellular ...

Loss of cardiac tetralinoleoyl cardiolipin in human and experimental heart failure

open access: yesJournal of Lipid Research, 2007
The mitochondrial phospholipid cardiolipin is required for optimal mitochondrial respiration. In this study, cardiolipin molecular species and cytochrome oxidase (COx) activity were studied in interfibrillar (IF) and subsarcolemmal (SSL) cardiac ...

Enhanced Na\u3csup\u3e+\u3c/sup\u3e/H\u3csup\u3e+\u3c/sup\u3e Exchange During Ischemia and Reperfusion Impairs Mitochondrial Bioenergetics and Myocardial Function [PDF]

open access: yes, 2008
Inhibition of Na+/H+ exchange (NHE) during ischemia reduces cardiac injury due to reduced reverse mode Na+/Ca2+ exchange. We hypothesized that activating NHE-1 at buffer pH 8 during ischemia increases mitochondrial oxidation, Ca2+ overload, and reactive ...

Cardiac myocyte-specific knock-out of calcium-independent phospholipase A2γ (iPLA2γ) decreases oxidized fatty acids during ischemia/reperfusion and reduces infarct size [PDF]

open access: yes, 2016
Calcium-independent phospholipase A(2)γ (iPLA(2)γ) is a mitochondrial enzyme that produces lipid second messengers that facilitate opening of the mitochondrial permeability transition pore (mPTP) and contribute to the production of oxidized fatty acids ...
