Ischemic preconditioning (IPC) is known to protect the heart against ischemia/reperfusion (IR)-induced injuries, and regional differences in the mitochondrial antioxidant state during IR or IPC may promote the death or survival of viable and infarcted cardiac tissues under oxidative stress. To date, however, the interplay between the mitochondrial antioxidant enzyme system and the level of reactive oxygen species (ROS) in the body has not yet been resolved. In the present study, we examined the...

The present study was designed to investigate the protein expression of nitric oxide synthase (NOS) and guanylyl cyclase (GC) activity in ischemia/perfusion (I/R) renal injury in rats. Renal I/R injury was experimentally induced by clamping the both renal pedicle for 40 min in Sprague-Dawley male rats. The renal expression of NOS isoforms was determined by Western blot analysis, and the activity of guanylyl cyclase was determined by the amount of guanosine 3', 5'-cyclic monophosphate (cGMP)...

The protective effects of baicalein, one of the flavonoids in Scutellaria baicalensis Georgi, were evaluated against 6-hydroxydopamine (6-OHDA)-induced neuronal damage in mice and cultured human neuroblastoma cells. Nigrostriatal damage was induced by stereotaxically injecting 6-OHDA into the right striatum. Baicalein was administered intraperitoneally 30 min before and 90 min after lesion induction. Animals received a further daily injection of baicalein for 3 consecutive days. Two weeks after...

a day, i.p.) for the last two days. Control groups were treated with either L-NAME for 1 week, indomethacin for 2 days, or without any drug treatment. The abundance of AQP1, AQP2 and AQP3 proteins in the kidney was determined by Western blot analysis. Indomethacin downregulated AQP channels, whereas L-NAME by itself showed no significant effects on them. The indomethacin-induced downregulation of AQP2 and AQP3 was significantly blunted in L-NAME-treated rats, while that of AQP1 was not affected....

Mitochondrial permeability transition has been shown to be involved in neuronal cell death. Mitochondrial monoamine oxidase (MAO)-B is considered to play a part in the progress of nigrostriatal cell death. The present study examined the effect of MAO inhibitors against the toxicity of 1-methyl-4- phenylpyridinium (MPP⁢) in relation to the mitochondrial permeability transition. Chlorgyline (a selective inhibitor of MAO-A), deprenyl (a selective inhibitor of MAO-B) and tranylcypromine (non-...

The promoting effect of hydrogen peroxide (H2O2) against the cytotoxicity of 1-methyl-4-phenylpyridinium (MPP⁢) in differentiated PC12 cells was assessed by measuring the effect on the mitochondrial membrane permeability. Treatment of PC12 cells with MPP⁢ resulted in the nuclear damage, decrease in the mitochondrial transmembrane potential, cytosolic accumulation of cytochrome c, activation of caspase-3, increase in the formation of reactive oxygen species (ROS) and depletion of GSH....

to the control value of 0.72⁑0.07 in a Ca2+-free/2 mM EGTA solution. After the protonophore CCCP (10μM) challenge to release mitochondrial Ca2+, the similar result was obtained. Ratio-difference before and after the application of DTBNP after pretreatment with CCCP was 0.46⁑0.09 (n=7). Simultaneous application of thapsigargin and CCCP completely abolished the DTBNP-induced [Ca2+]i increase. The above results together indicate that the increase of [Ca2+]i by DTBNP resulted from the...

The preventive effects of gene transfer of human copper/zinc superoxide dismutase (Cu/ZnSOD) on the development of cerebral vasospasm after subarachnoid hemorrhage (SAH) were examined using a rat model of SAH. An experimental SAH was produced by injecting autologous arterial blood twice into the cisterna magna, and the changes in the diameter of the middle cerebral artery (MCA) were measured. Rats subjected to SAH exhibited a decreased diameter with an increased wall thickness of MCA that were...

In this study, the authors investigated whether death of vascular smooth muscle cell (VSMC) had a pathological pertinence. Conditioned media obtained from rat aorta smooth muscle cell (SMC) that were induced death by expressing FADD in the absence of tetracycline (FADD-SMC) triggered death of normal SMC. DNA fragmentation and caspase-3 activation were observed in dying SMC by conditioned media. FADD-SMC showed transcriptional activation of tumor necrosis factor (TNF)-α. Conditioned medium...

To characterize cytosolic Ca2⁢ fluctuations under metabolic inhibition, rat ventricular myocytes were exposed to 200μM 2,4-dinitrophenol (DNP), and mitochondrial Ca2⁢, mitochondrial membrane potential (ΔΨm), and cytosolic Ca2⁢ were measured, using Rhod-2 AM, TMRE, and Fluo-4 AM fluorescent dyes, respectively, by Laser Scanning Confocal Microscopy (LSCM). Furthermore, the role of sarcolemmal Na⁢/Ca2⁢ exchange (NCX) in cytosolic Ca2⁢ efflux was studied in...
