of Tat-SOD increased Bcl-2 and heat shock protein 70 (hsp70) expressions in cells exposed to STZ, which might be partly responsible for the effect of Tat-SOD. These results suggest that an increased of free radical scavenging activity by transduction of Tat-SOD enhanced the tolerance of the cell against oxidative stress in STZ-treated MIN6N cells. Therefore, this Tat-SOD transduction technique may provide a new strategy to protect the pancreatic β cell destruction in ROS-mediated diabetes.

The cellular mechanisms that contribute to the acceleration of atherosclerosis in diabetes are poorly understood. Therefore, the potential mechanisms involved in the diabetes-dependent increase in vascular smooth muscle cell (VSMC) proliferation was investigated. Using primary culture of VSMC from streptozotocin-induced diabetic rat aorta, cell proliferation assay showed two-fold increase in cell number accompanied with enhanced superoxide generation compared to normal VSMC, 2 days after...

Melatonin, a pineal gland hormone, is believed to act as an antioxidant via the stimulation of radical detoxifying enzymes and scavenging of free radicals. In this study, effects of in vitro and in vivo treatments of melatonin on the cisplatin-induced lipid peroxidation, LDH release and plasma creatinine were determined in rabbit renal cortical cells. The level of malondialdehyde (MDA) was assayed as an index of lipid peroxidation and the level of LDH release as an indicator of cellular damage....

It has been proposed that nitirc oxide is involved in the pathogenesis of cerebral ischemia-reperfusion. Because superoxide production is also enhanced during reperfusion, the cytotoxic oxidant peroxynitrite could be formed, but it is not known if this occurs following global forebrain ischemia-reperfusion. We examined whether peroxynitrite generation is increased in the vulnerable regions after forebrain ischemia- reperfusion. Transient forebrain ischemia was produced in the conscious rat by...

(SOD, 50 u/ml) potentiated an inhibitory effect of ACh on the PE (10⁣7 M)-induced contraction. It has been known that platelet activating factor itself induces iNOS. Platelet activating factor (PAF, 10⁣7 M) inhibited PE (10⁣7 M)-induced contraction. Pretreatment with L-NMMA (30 mM) or L-NAME (30 mM) significantly blocked the inhibitory action of PAF on PE-induced contraction. L-NMMA (100 mM) or L-NAME (100 mM) reduced nerve conduction velocity (NCV) relevant to nNOS in rat...

(SOD). First, we have observed that selenium (10μM), cadmium (100μM), mercury (100μM) or manganese (1 mM) treatment induced apoptotic phenomena like DNA fragmentation, chromatin condensation and caspase-3-like cysteine protease activation in MC3T3E1 osteoblasts. Concomitant treatment of antioxidant; N-acetyl-L-cysteine (NAC), reduced-form glutathione (GSH), or superoxide dismutase (SOD), prevented apoptosis induced by each of the transition metal ions. Catalase or dimethylsulfoxide (DMSO) has...

soluble guanylyl cyclase inhibitor. Cu/Zn SOD (100 U/ml), the free radical scavenger, had little effect on basal IBa, and SIN-1 (10μM) inhibited peak IBa by 32.4⁑5.8% (n=5) in the presence of Cu/Zn SOD. In a cell clamped at a holding-potential of ⁣40 mV, application of 10μM histamine induced an inward current. The histamine-induced inward current was markedly and reversibly inhibited by 10μM SIN-1, and this effect was abolished by ODQ (1μM). In addition, SIN-1 markedly increased...

The present study investigated the stimulatory effects of iron (or ascorbate) on cyclosporine-induced kidney mitochondrial damage. Damaging effect of 50 μM cyclosporine plus 20 μM Fe2⁢ on mitochondrial lipids and proteins of rat kidney and hyaluronic acid was greater than the summation of oxidizing action of each compound alone, except sulfhydryl oxidation. Cyclosporine and 100 μM ascorbate showed an enhanced damaging effect on lipids but not on proteins. The peroxidative action of...

This study was undertaken to examine the effect of ethanol on Na⁢-dependent phosphate (Na⁢-Pi) uptake in opossum kidney (OK) cells, an established renal proximal tubular cell line. Ethanol inhibited Na⁢-dependent component of phosphate uptake in a dose-dependent manner with I50 of 8.4%, but it did not affect Na⁢-independent component. Similarly, ethanol inhibited Na⁢-dependent uptakes of glucose and amino acids (AIB, glycine, alanine, and leucine). Microsomal...

dismutase (SOD). H2O2 (ferrithiocyanate method), LPO (as thiobarbiturate reactive substances), and cytokines (IL-1β, IL-6, TNF-α; enzyme-linked immunosorbent assay) and NF-κB activation (electrophoretic mobility shift assay) were analyzed in acinar cells treated with or without PMA-primed neutrophils in the absence or presence of NAC (10 mM) or SOD (300 U/ml). As a result, the productions of H2O2, LPO and TNF-α were increased with the ratio of PMA-primed neutrophils to acinar cells while the...
