Luminol (5-amino-2,3-dihydro-1,4-phthalazinedione) and lucigenin (bis-N-methylacridinium nitrate) are used to detect reactive oxygen species (ROS). Luminol bioluminescence detects mainly to neutrophil myeloperoxidase (MPO) activity, and lucigenin bioluminescence detects NADPH oxidase activity and extracellular superoxide production of macrophages (39 (link),40 (link)). Na-luminol and lucigenin (Santa Cruz Biotechnology) were dissolved in phosphate buffered saline to form 20-mg/ml and 2.5-mg/ml stock solutions, respectively. Anesthetized mice were injected intraperitoneally with 150 mg/kg luminol (days 0, 1, 2, and 4) or 25 mg/kg lucigenin (days 0, 2, 6, and 10). Bioluminescence imaging was performed 10 minutes postinjection using an IVIS Lumina II. Acquisition time was 60 seconds, F-stop 1, Binning 8. Data were analyzed and ROIs were applied; luminescence was expressed as total radiance (photons/second/cm2/steradian) within the ROIs.

Luminol, Lucigenin, Isoluminol, HRP Type VI, PMA, SOD from bovine erythrocytes and zymosan were obtained from Sigma (St Louis, MO). FCS, HBSS, H2DCF-DA were from Invitrogen Molecular Probes (Oregon). DMEM was purchased from PAA (Vienna, Austria), anti-mouse antibodies CD16/CD32, CD11b-FITC, CD11c-APC, F4/80-PE-Cy5 were obtained from BD Bioscience (Mountain View, CA). Rich medium (YPD) and synthetic complete were prepared essentially as described (Kaiser et al., 1994 ). BMDM media are composed of DMEM, 10% heat-inactivated FCS, 20% l-conditioned medium. mDC media are composed of DMEM, 10% heat-inactivated FCS, 10% X-conditioned medium. C. albicans strains were grown at 30°C in YPD medium overnight, diluted to an OD600 = 0.2 the next morning, grown to the logarithmic growth phase and used for the experiment unless indicated otherwise. For the preparation of mature filaments, an overnight culture of C. albicans was diluted 1:10 in YPD + 10% FCS and grown at 37°C for 3–4 h. For experiments requiring stimulation of macrophages with filaments, an aliquot of each culture was pelleted and the dry weight was determined by routine procedures. Aliquots of cultures equalling the indicated dry weights of yeast or filaments were used for experiments. Typically, 4 × 104 yeast cells correspond to 1 μg dry weight.

This investigation conformed to the National Institutes of Health Guidelines on the Use of Laboratory Animals, and was approved by the Institute’s Animal Ethics Committee. Experiments were performed on wild type (WT) C57BL/6 and LXR-deficient [LXRα-, LXRβ-, or LXRα/β double-knockout (KO)] male mice. Pharmacologic experiments employed LXR endogenous agonist 22(R)-hydroxycholesterol [22(R)-HC] and synthetic agonist GW3965.14 (link), 15 (link) In the acute MI/R protocol, reperfusion commenced for 24 hours following 30 minutes of ischemia. Mice were randomly assigned to the following groups: sham, vehicle, 22(R)-HC (20 mg/kg), or GW3965 (20 mg/kg) by intraperitoneal injection (IP) 15 minutes before reperfusion. To observe the long-term cardioprotective effect of LXRα/β dual agonists, mice were randomly assigned to one of the following groups: sham, vehicle, 22(R)-HC (20 mg/kg), or GW3965 (20 mg/kg) by IP injection 15 minutes before reperfusion, and daily following reperfusion for 4 weeks. Other experiments were designed for MI/R outcome determination in LXRα-, β-, and α/β double-deficiency mice and their WT littermates. Myocardial apoptosis was determined by terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) technique and cardiac caspase-3 activity. Myocardial infarct size was determined by Evans blue-TTC double staining methods.16 (link) In-vivo cardiac function was determined by echocardiography.17 (link) Viable myocardium was assessed via micro-positron emission tomography/computed tomography (micro-PET/CT) scanning. Myocardial reactive oxygen species generation was measured by confocal microscopy via in-situ dehydroetidium (DHE) stain or lucigenin-enhanced chemiluminescence. Myocardial nitrative stress was assessed by nitrotyrosine content. In-vivo knockdown of cardiac-specific LXRα or LXRβ expression was achieved by intramyocardial delivery of siRNA. In-vivo cardiac gene overexpression was achieved by adenoviral-encoded LXRα or LXRβ transfection. An expanded Methods appears in the Data Supplement.

The enhanced lucigenin-derived chemiluminescence method was adopted to measure the nicotinamide adenine dinucleotide phosphate (NADPH) oxidase activity and ROS level in aortic tissues or A7r5 cells. Both dark-adapted 100 μM NADPH and 5 μM lucigenin were used to trigger the photon emission and the background chemiluminescence was detected by a luminometer (Turner, CA, USA). The data were presented as the mean of light unit (MLU)/min/mg protein.

Superoxide levels in thoracic and abdominal aorta rings were assessed by lucigenin-enhanced chemiluminescence as previously documented [25 (link)]. Samples were added to polypropylene cuvettes with PBS and lucigenin (5 μmol/L). After 10 min of dark adaptation, basal chemiluminescence was measured for 5 min using a luminometer (FB15, Zylux, Maryville, TN, USA). For measurement of NOX activity, luminescence was assessed using NADH (0.2 and 1 mmol/L, ST358, Beyotime, Shanghai, China) or NADPH (0.2 and 1 mmol/L, ST360, Beyotime) as substrates. The source of superoxide was determined by treating samples with apocynin (targeting NOX, 100 µmol/L, 178385, Sigma-Aldrich), L-NAME (targeting eNOS, 100 µmol/L) or oxypurinol (targeting XO, 100 µmol/L, O6881, Sigma-Aldrich) for 30 min prior to chemiluminescence measurement. Relative light unit (RLU) values were normalized to the surface area of each vessel.

MPO activity was assessed by luminol imaging22 (link) of the isolated CD11b+Ly6G+ and CD11b+ myeloid cells; 1×105 isolated myeloid cells were added to 100 mM luminol, 50 µM L-012, or 100 µM lucigenin in colorless DMEM media in a 96-well black walled plate. Cells were immediately imaged for 120 min using the IVIS 100 bioluminescence imaging system (Perkin Elmer/Caliper Life Sciences, MA, USA) at 37°C under 5% CO2 flow. Typical acquisition parameters were as follows: acquisition time, autoexposure; binning, 8; FOV, 15 cm; f/stop, 1; filter, open; image-image interval, 5 min; total number of acquisitions, 24. Bioluminescence photon flux (photons/s) data were analyzed by ROI measurements with background subtraction in Living Image 4.5 (Perkin Elmer/Caliper Life Sciences); these raw data were imported into Excel (Microsoft, WA, USA), averaged in each individual experiment if done in duplicate or triplicate wells. Total photon flux for each experiment subtracted the total photon flux of reporter alone controls at each time point. For the CD11b+ myeloid cells, the photon flux was normalized to 1000 CD11b+ cells quantified by FACS. For luminol, the area under the curve was calculated from images taken at 5–60 min. For L-012, the area under the curve was calculated from images taken at 5–90 min and lucigenin was quantified using images taken at 5–25 min. The area under the curve for each reporter was taken from n=3 independent isolation experiments.
