The Na(+)/Ca(2+) exchanger (NCX), a 10-transmembrane domain protein mainly involved in the regulation of intracellular Ca(2+) homeostasis, plays a crucial role in cerebral ischemia. In the present paper, we characterized the effect of the newly synthesized compound
The inhibition of the Na+/H+ exchanger during cardiac ischemia and reperfusion has been shown to be beneficial for the preservation of the cellular integrity and functional performance. The aim of the present investigation was to come up with potent and selective benzoylguanidines as NHE inhibitors
Necroptosis, or caspase-independent programmed cell death, is known to be involved in various pathological conditions, such as ischemia/reperfusion injury, myocardial infarction, atherosclerosis, and inflammatory bowel diseases. Although several inhibitors of necroptosis have been identified, none
We determined in intact hearts whether inhibition of Na(+)/H(+) exchange (NHE) decreases intracellular Na(+) and Ca(2+) during ischemia and reperfusion, improves function during reperfusion, and reduces infarct size. Guinea pig isolated hearts were perfused with Krebs-Ringer solution at 37 degrees
Patients with heart disease have a higher risk to develop cardiac arrhythmias, either spontaneously or drug-induced. In this study, we have used a rabbit model of myocardial infarction (MI) with severe left ventricular systolic dysfunction (LVSD) to study potential drug-induced cardiac risks with
The poly(ADP-ribose)polymerases (PARPs) catalyse the transfer of ADP-ribose units from the substrate NAD(+) to acceptor proteins, biosynthesising polyanionic poly(ADP-ribose) polymers. A major isoform, PARP-1, has been the target for design of inhibitors for over twenty-five years. Inhibitors of the
Wharton's jelly-derived mesenchymal stromal cells (WJ-MSCs) have distinct immunomodulatory and protective effects against kidney, liver, or heart injury. Limited studies have shown that WJ-MSCs attenuates oxygen-glucose deprivation-mediated inflammation in hippocampal slices. The neuroprotective
Preclinical investigations support the concept that donor cells more oriented towards a cardiovascular phenotype favor repair. In light of this philosophy, we previously identified HDAC1 as a mediator of cardiac mesenchymal cell (CMC) cardiomyogenic lineage commitment and paracrine signaling potency
NLRP3 inflammasome plays critical roles in a variety of human diseases and represents a promising drug target. In this study, we established the in vivo functional activities of JC124, a previously identified NLRP3 inflammasome inhibitor from our group, in mouse models of Alzheimer's disease and
Transient receptor potential melastatin 8 (TRPM8) is a temperature-sensing ion channel mainly expressed in primary sensory neurons (Aδ-fibers and C-fibers in the dorsal root ganglion). In this report, we characterized KPR-5714
The sodium-hydrogen exchanger-isotype 1 (NHE-1) plays a critical role in myocardial ischemia-reperfusion injury. While studies employing less selective sodium-hydrogen inhibitors have demonstrated antiarrhythmic activity, only one study has examined the in vivo efficacy of selective NHE-1 inhibition
Using canine ventricular arrhythmia models induced by two-stage coronary ligation, digitalis, adrenaline, coronary ligation and reperfusion, and programmed electrical stimulation (PES), we examined the antiarrhythmic or proarrhythmic effects of sematilide,
Physiological levels of H(2)S exert neuroprotective effects, whereas high concentrations of H(2)S may cause neurotoxicity in part via activation of NMDAR. To characterize the neuroprotective effects of combination of exogenous H(2)S and NMDAR antagonism, we synthesized a novel H(2)S-releasing NMDAR
BACKGROUND
The formation of the NLRP3 inflammasome in the heart during acute myocardial infarction amplifies the inflammatory response and mediates further damage. Glyburide has NLRP3 inhibitory activity in vitro but requires very high doses in vivo, associated with hypoglycemia. The aim of this
