Experimental details: Western blot analysis of iNOS was performed by loading 20 µg of RAW264 whole cell lysate untreated (left lane) or stimulated with LPS at 1 µg/mL for 16 hours (right lane) and 10 µL of PageRuler Plus Prestained Protein Ladder (Product # 26619) onto a 4-20% Tris-Glycine polyacrylamide gel. Proteins were transferred to a nitrocellulose membrane and blocked with 5% Milk in TBST for at least 1 hour. The membrane was probed with an iNOS Rabbit polyclonal antibody (Product # PA1-036) at a dilution of 1:1000 overnight at 4°C on a rocking platform, washed in TBST, and probed with a Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, HRP conjugate (Product # A27036) at a dilution of 1:1000 for 1 hour. Chemiluminescent detection was performed using SuperSignal West Pico (Product # 34087).

Experimental details: Western blot was performed using Anti-iNOS Polyclonal Antibody (Product # PA1-036) and a 130kDa band corresponding to Nitric oxide synthase, inducible, was observed to be upregulated in RAW 264.7 cells upon treatment with LPS. Whole cell extracts (30 µg lysate) of RAW 264.7 (Lane 1) and RAW 264.7 treated with LPS (Lane 2) were electrophoresed using NuPAGE™ 4-12% Bis-Tris Protein Gel (Product # NP0321BOX). Resolved proteins were then transferred onto a Nitrocellulose membrane (Product # IB23001) by iBlot® 2 Dry Blotting System (Product # IB21001). The blot was probed with the primary antibody (1:1000 dilution) and detected by chemiluminescence with Goat anti-Rabbit IgG (H+L) Superclonal™ Recombinant Secondary Antibody, HRP (Product # A27036,1:4000 dilution) using the iBright FL 1000 (Product # A32752). Chemiluminescent detection was performed using Novex® ECL Chemiluminescent Substrate Reagent Kit (Product # WP20005). An uncharacterized band (*) was also observed at ~60kDa.

Experimental details: Immunohistochemistry was performed on normal deparaffinized human Heart tissue. To expose target proteins, heat induced antigen retrieval was performed using 10mM sodium citrate (pH6.0) buffer, microwaved for 8-15 minutes. Following antigen retrieval tissues were blocked in 3% BSA-PBS for 30 minutes at room temperature. Tissues were then probed at a dilution of 1:200 with a rabbit polyclonal antibody recognizing iNOS (Product # PA1-036) or without primary antibody (negative control) overnight at 4°C in a humidified chamber. Tissues were washed extensively with PBST and endogenous peroxidase activity was quenched with a peroxidase suppressor. Detection was performed using a biotin-conjugated secondary antibody and SA-HRP, followed by colorimetric detection using DAB. Tissues were counterstained with hematoxylin and prepped for mounting.

( C ) Representative photomicrographs and quantification of immunofluorescence (red) for nNOS, iNOS, and eNOS in confocal microscopic aortic sections. Scale bar, 20 mum. Results are the mean +- SEM from wild-type (n = 8) and CD (n = 8) mice. * P < 0.05 by Student's t-test.

Experimental details: Figure 1 iNOS immunolabeling of amoeboid microglia in retinas of quail embryos at 8 and 9 days of incubation. Confocal micrographs of QH1 (green) and anti-iNOS (red) double-immunolabeled amoeboid microglial cells in whole-mounted retinas (WM) and retinal cross-sections (CS) of quail embryos at 8 (E8, A , B ) and 9 days of incubation (E9, C , D ). Cell nuclei in retinal cross sections are stained with Hoechst (blue). All QH1-positive amoeboid microglial cells in E8 and E9 embryo retinas are located in the nerve fiber layer (NFL) and are also immunolabeled with the anti-iNOS antibody. Anti-iNOS labeling of microglial cells is similar to QH1 labeling but with some differences. Thus, QH1 labels the entire microglial cell profile, including lamellipodia, whereas anti-iNOS labeling is exclusively cytoplasmic in distinct zones of the soma and cell processes. OPL: outer plexiform layer; INL: inner nuclear layer; IPL: inner plexiform layer; GCL: ganglion cell layer. Scale bar, 50 um for A and C; 60 um for B and D.

Experimental details: Figure 1 Narrow-leafed lupin (NLL) gamma-conglutin decreases the mRNA expression and protein levels of TNFalpha, IL-1beta, and iNOS on lipopolysaccharide (LPS)-induced inflammation pancreatic cells. PANC-1 cells were incubated for 24 h with LPS alone or gamma-conglutin + LPS. ( A ) The bar graph shows mRNA levels determined by real-time RT-qPCR of TNFalpha, iNOS, and IL1beta. ( B ) The bar graph shows protein levels determined by immunoblotting of TNFalpha, iNOS, and IL1beta. Average value from triplicate experiments of each biomarker were relativized to the average value of their housekeeping actin protein in control samples. Then, average values from challenge experiments (calculated in the same way than controls) are relativized to these from their respective control values previously calculated. Data represent mean +- SD from three independent experiments. C: Untreated control culture cells; LPS: LPS-treated culture cells; LPS + gamma: LPS + gamma-conglutin challenge. p < 0.05 represents statistically significant differences associated with each figure. p * < 0.05 LPS versus C; p ** < 0.05 LPS + gamma-conglutin versus LPS. Challenges were made with LPS and/or gamma-conglutin protein at 1 mug/mL and 25 mug, respectively.

Experimental details: Figure 2 MSC-Ex restores the PPARalpha activity in HaCaT cells. ( A ) HaCaT cells were treated as described in Fig. 1 and western blot analyses were performed using primary antibodies for PPARalpha, NF-kappaB-65, p-NF-kappaB-p65 Ser536 , IkappaB, p-IkappaB Ser32/36 and iNOS. beta-Actin was used as the loading control. ( B ) The protein levels of NF-kappaB were determined by ELISA. Columns represent the means of three independent experiments; bars indicate standard deviations.). * P < 0 . 05 , **P < 0 . 005 , ***P < 0 . 001 .
