Abstract
Elimination of leukemia stem cells (LSCs) is necessary for the destruction of malignant cell populations. Owing to the very small number of LSCs in leukemia cells, xenotransplantation studies are difficult in terms of functionally and pathophysiologically replicating clinical conditions of cell culture experiments. There is currently a limited number of lead compounds that target LSCs. Using the LSC-xenograft zebrafish screening method we previously developed, we found that the fluorescent compound 3,3'-dipentyloxacarbocyanine iodide (DiOC5(3)) selectively marked LSCs and suppressed their proliferation in vivo and in vitro. DiOC5(3) had no obvious toxicity to human umbilical cord blood CD34+ progenitor cells and normal zebrafish. It accumulated in mitochondria through organic anion transporter polypeptides that are overexpressed in the plasma membrane of LSCs, and induced apoptosis via ROS overproduction. DiOC5(3) also inhibited the nuclear translocation of NF-κB through the downregulation of LSC-selective pathways, as indicated from DNA microarray analysis. In summary, DiOC5(3) is a new type of anti-LSC compound available for diagnostic imaging and therapeutics that has the advantage of being a single fluorescent chemical.

Abstract
A structure-activity relationship for symmetrical cyanine inhibitors of human tau aggregation was elaborated using a filter trap assay. Antagonist activity depended on cyanine heterocycle, polymethine bridge length, and the nature of meso- and N-substituents. One potent member of the series, 3,3'-diethyl-9-methylthiacarbocyanine iodide (compound 11), retained submicromolar potency and had calculated physical properties consistent with blood-brain barrier and cell membrane penetration. Exposure of organotypic slices prepared from JNPL3 transgenic mice (which express human tau harboring the aggregation prone P301L tauopathy mutation) to compound 11 for one week revealed a biphasic dose response relationship. Low nanomolar concentrations decreased insoluble tau aggregates to half those observed in slices treated with vehicle alone. In contrast, high concentrations (> or =300 nM) augmented tau aggregation and produced abnormalities in tissue tubulin levels. These data suggest that certain symmetrical carbocyanine dyes can modulate tau aggregation in the slice biological model at concentrations well below those associated with toxicity.

Abstract
The mitochondrial membrane potential (DeltaPsi(m)) is an important indicator of the energetic state of both the mitochondria and the cells. To develop a sensitive, convenient, and rapid method for the measurement of DeltaPsi(m), we carried out cell fluorescence assays using the Agilent 2100 bioanalyzer system which, unlike the conventional flow cytometry, is based on microfluidic technology employing fluorescence detection with a 3,3'-dihexyloxacarbocyanine iodide (DiOC(6)(3)) fluorescent probe. The use of DiOC(6)(3) in the fluorometer was shown to be feasible for monitoring variations in DeltaPsi(m) in the mitochondria isolated from rat liver and treated with rotenone, succinate, ADP, and carbonylcyanide-p-trifluoromethoxyphenylhydrazone (FCCP). Flow cytometry analysis showed severe reduction of fluorescence intensity in Jurkat cells after treatment with 1.0 and 10 microM FCCP. However, fluorescence microscopy demonstrated obvious accumulation of fluorescence in the mitochondria and induction of diffuse cytoplasmic fluorescence not localized to the mitochondria in these cells. The dose response range of DiOC(6)(3) in the Agilent 2100 bioanalyzer system for yielding sufficient fluorescence intensity in the mitochondria of the cells was 20 nm-2.0 microM. Furthermore, significant reduction of fluorescence intensity in the cells stained with 2.0 microM DiOC(6)(3) was observed after treatment with 10 microM FCCP for 30 min. These results indicate that the Agilent 2100 bioanalyzer is potentially useful for monitoring DeltaPsi(m) in cell assays.

Abstract
Release of cytochrome c from the mitochondria plays an integral role in apoptosis; however, the mechanism by which cytochrome c is released remains one of the conundrums that has occupied the field. Recently, evidence has emerged that the commitment to death may be regulated downstream of cytochrome c release; therefore the mechanism of release must be subtle enough for the cell to recover from this event. In this review, we discuss the evidence that cytochrome c release is mediated by Bcl-2 family proteins in a process that involves only outer membrane permeability but leaves inner membrane energization, protein import function and the ultrastructure of mitochondria intact.

Abstract
Mitochondrial membrane potential, in situ, is an important indicator of mitochondrial function and dysfunction. Because of recent interest in the role of mitochondria in signaling, cell injury and cell death, there is a need for a convenient, sensitive and accurate method for the measurement of the mitochondrial membrane potential, Deltapsim, in situ, in a heterogeneous cell population. We have adapted a flow cytometry method for the quantitative measurement of DeltaPsim which utilizes the lipophilic, cationic, fluorescent probe 3,3'-dihexyloxacarbocyanine iodide (DiOC6(3)). We developed a new protocol in which cells are equilibrated with very low dye concentrations (<1 nM). Only under these condition, the cell fluorescence appears to be correlated with the magnitude of DeltaPsim, as evident from the sensitivity of the fluorescence to low concentrations of uncouplers, ionophores and inhibitors of the mitochondrial proton pumps. The magnitude of the plasma membrane potential, DeltaPsip, also affects cell fluorescence, and a procedure that corrects for this effect is outlined. This method offers a distinct advantage over existing methods for estimation of Deltapsim by flow cytometry.

Abstract
This article provides an updated overview of the plethora of complex I inhibitors. The inhibitors are presented within the broad categories of natural and commercial compounds and their potency is related to that of rotenone, the classical inhibitor of complex I. Among commercial products, particular attention is dedicated to inhibitors of pharmacological or toxicological relevance. The compounds that inhibit the NADH-ubiquinone reductase activity of complex I are classified according to three fundamental types of action on the basis of available evidence and recent insights: type A are antagonists of the ubiquinone substrate, type B displace the ubisemiquinone intermediate, and type C are antagonists of the ubiquinol product.

Abstract
Aging is associated with mitochondrial dysfunction in excitable tissues such as nerve and muscle. However, it is not known if immunosenescence is similarly associated with mitochondrial dysfunction in lymphocytes. We have found that spleen lymphocytes from old mice have lower respiration rates than lymphocytes from young mice. Cyclosporin, an inhibitor of the mitochondrial Permeability Transition, PT, restored normal respiration rates to lymphocytes from old mice, suggesting enhanced susceptibility to PT activation. Lymphocytes from old mice also had a lower mitochondrial membrane potential (delta psi m) than lymphocytes from young mice, which was also restored by cyclosporin. Oxidized FAD fluorescence was higher in lymphocytes from old mice suggesting a more oxidized state, which may be the cause of the enhanced activation of PT. Incubation of lymphocytes from old mice with the lipophilic cationic dye DiOC6(3), which inhibits electron transport, induced the appearance of apoptotic cells. These findings suggest that the mitochondrial PT is more susceptible to activation in lymphocytes from old mice. This activation may inhibit energy metabolism and enhance apoptosis, and may therefore contribute to immunosenescence.

Abstract
The mammalian mitochondrial electron transport chain catalyzes the oxidation of NADH at pH 8.0 and pH 6.5, and the oxidation of NADPH at pH 6.5. The pH-dependencies of the rate of steady-state oxidation of NADPH and NADH by Complex I as well as by its flavoprotein fraction have been extensively studied by the laboratory of Hatefi. One model to explain these pH-dependent oxidations was proposed by Bakker and Albracht (Biochim. Biophys. Acta 850 (1986) 413-422 and 423-428, modified by Van Belzen and Albracht (Biochim. Biophys Acta 974 (1989) 311-320), which predicts that Complex I is a heterodimer with promoter B, containing FMN and Fe-S clusters 1-4 in stiochiometric amounts, catalyzing NADH oxidation at pH 8, and Protomer A, containing FMN and Fe-S clusters 2, 4, catalyzing NAD(P)H oxidation at pH 6.5. A pH-dependent transfer of electrons from protomer A Fe-S clusters 2, 4 to protomer B Fe-S clusters 2, 4 is an obligate step in the oxidation of NAD(P)H at low pH. Strict interpretation of this model allows for only three types of inhibitor: one which inhibits all three oxidase activities (type 1); one which inhibits NADH oxidase, pH 8.0 (type 4) and a third which inhibits NAD(P)H oxidase, pH 6.5 (type 5). Another possibility is that there are three separate pathways of oxidation of NAD(P)H, which would allow for a total of seven different types of inhibitor, e.g., the three types above plus type 2 inhibiting NADH oxidase pH 8.0 and pH 6.5; type 3 inhibiting NADH oxidase pH 8.0, and NADPH oxidase pH 6.5; type 6 inhibiting NADH oxidase pH 6.5; and type 7 inhibiting NADPH oxidase pH 6.5. Using a series of thirteen inhibitors of Complex I activity and the chemical modification reagent ethoxyformic anhydride (EFA), four different inhibitor types were found: seven inhibitors of type 1, four inhibitors of type 2, one inhibitor of type 3 and one inhibitor of type 4. Treatment of submitochondrial particles (SMP) with EFA abolished NADH-dependent reduction of coenzyme Q at both pH 8.0 and 6.5, while inhibiting NADPH-dependent reduction of coenzyme Q at pH 6.5 by only 30%. These results do not support the heterodimer model of Complex I electron transport of Bakker and Albracht, but do support three separate electron flow pathways through complex 1 from reduced pyridine nucleotides to coenzyme Q. A new model of electron flow through Complex I based on these finding is proposed.

Abstract
Certain indocarbocyanine, thiacarbocyanine, and oxacarbocyanine dyes possessing short alkyl side-chains (one to five carbons) are potent inhibitors of mammalian mitochondrial NADH-ubiquinone reductase (EC 1.6.99.3) activity (Anderson et al., Biochem Pharmacol 41: 677-684, 1991; Anderson et al., Biochem Pharmacol 45: 691-696, 1993; Anderson et al., Biochem Pharmacol 45: 2115-2122, 1993), and act similarly to rotenone. This study examines the inhibitory capacities of twelve other carbocyanine dyes (six indocarbocyanines, four oxacarbocyanines, and two thiacarbocyanines) possessing long alkyl side-chains (seven to eighteen carbons with both saturated and unsaturated side-chains) on mitochondrial NADH, succinate and cytochrome c oxidase activities. Three of the indocarbocyanines inhibited electron transport chain activity, while three were non-inhibitory. Two of the oxacarbocyanines also inhibited electron transport chain activity, while the other two were without effect. Both the thiacarbocyanines were non-inhibitory. In contrast to previous studies, the long alkyl side-chain carbocyanines exhibited a broad spectrum of inhibition of respiratory chain activity, affecting either oxidation of all three substrates or of NADH and cytochrome c, rather than specific inhibition of mitochondrial NADH-ubiquinone reductase activity, indicating that there could be multiple binding sites for these compounds. The five inhibitory long side-chain carbocyanines also inhibited reduction of ferricyanide and coenzyme Q1 by NADH, using submitochondrial particles, but not when tested with purified complex I, indicating that the mitochondrial inner membrane was an integral component in their inhibitory capacity. No general correlation of side-chain length or degree of unsaturation and inhibitory capacity was discernible.
