- Immunofluorescent analysis of NFkB p105/p50 Antibody was done on 70% confluent log phase HeLa cells. The cells were fixed with 4% paraformaldehyde for 15 minutes, permeabilized with 0.25% Triton™ X-100 for 10 minutes, and blocked with 5% BSA for 1 hour at room temperature. The cells were labeled with NFkB p105/p50 Antibody (Product # 38-5600) at 1µg/mL in 1% BSA and incubated for 3 hours at room temperature and then labeled with Alexa Fluor 488 Goat Anti-Rabbit IgG Secondary Antibody (Product # A-11008) at a dilution of 1:400 for 45 minutes at room temperature (Panel a: green).

- Flow cytometry analysis of NFkB was done on HeLa cells. Cells were fixed with 70% ethanol for 10 minutes, permeabilized with 0.25% Triton™ X-100 for 20 minutes, and blocked with 5% BSA for 30 minutes at room temperature. Cells were labeled with NFkB Rabbit Polyclonal Antibody (513500, red histogram) or with rabbit isotype control (pink histogram) at 3-5 ug/million cells in 2.5% BSA. After incubation at room temperature for 2 hours, the cells were labeled with Alexa Fluor® 488 Goat Anti-Rabbit Secondary Antibody (A11008) at a dilution of 1:400 for 30 minutes at room temperature. The representative 10,000 cells were acquired and analyzed for each sample using an Attune® Acoustic Focusing Cytometer. The purple histogram represents unstained control cells and the green histogram represents no-primary-antibody control.

Mice were infected with ECwt and at thre dayspost-inoculation (d.p.i.) their small intestinal villi were isolated.Villi were analysed by immunocytochemistry (A) or flow cytometry (B) (n= 2 mice for each analysis). A: the immunocytochemistry analysis ofvillus cross-sections was performed by using rabbit polyclonalanti-rotavirus structural proteins (SP) antibody (Ab), horseradishperoxidase-conjugated goat anti-rabbit secondary Ab andaminoethylcarbazole chromogen. Cross-sections used inimmunocytochemistry were treated with 50 mM NH4Cl and then incubatedwith goat Ab against COX, ERp57, Hsc70, Hsp70, PDI, PPARI3 or rabbit Abagainst NF-IoB. Fluorescein isothiocyanate (FITC)-conjugated donkeyanti-goat Ab or FITC-conjugated donkey anti-rabbit Ab were added andsections were examined with a fluorescence microscope (VanGuard); B:flow cytometry analysis of COX, Hsc70, NF-IoB, Hsp70, PDI o PPARI3expression was performed in intestinal epithelial cells (IEC) isolatedfrom infected villi from ECwt-infected mice. Methanol/acetic acid-fixedIEC were incubated with goat primary Abs against the above mentionedproteins mixed with rabbit primary Abs against rotavirus SP.FITC-conjugated mouse anti-goat IgG Abs and phycoerythrin-conjugatedanti-rabbit IgG Abs were used

The NO-OGD/R cells served as a control. (B-I) Bar graphs show the quantitative analyses of western blots as ratios of Itgalpha5/beta-actin (B), KLF4/beta-actin (C), E-selectin/beta-actin (D), VCAM-1/beta-actin (E), ICAM-1/beta-actin (F), p-NF-kappaB/total NF-kappaB (G), Claudin-5/beta-actin (H), and ZO-1/beta-actin (I) (n = 4 per experimental group). Note that the expressions of Itgalpha5, KLF4, and TJPs (Claudin-5 and ZO-1) in the si-XIST-treated bEnd3 cells were markedly reduced, but the expressions of three CAMs including E-selectin, VCAM-1, and ICAM-1 and the p-NF-kappaB were significantly elevated relative to the si-Ctl-treated group at 24 h restoration from OGD. *p < 0.05, **p < 0.01, and ***p < 0.001.

Note that the expressions of Itgalpha5, KLF4, and TJPs (Claudin-5 and ZO-1) in the si-XIST + NC inhibitor (NC-I)-treated bEnd3 cells markedly decreased, but the expressions of three CAMs including E-selectin, VCAM-1, and ICAM-1 and the p-NF-kappaB were significantly elevated relative to the si-Ctl + NC-I-treated group at 24 h restoration from OGD. However, these effects were significantly rescued by inhibiting the levels of miR-92a in the bEnd3 cells. *p < 0.05, **p < 0.01, and ***p < 0.001.

- The effect of overexpression of KLF4 on the expression of three cell adhesion molecules, phosphorylated NF-kappaB, and tight junction proteins in bEnd3 cells under OGD/R conditions. a Representative images of western blot for the expression of KLF4 in the bEnd3 cells in the control plasmid (mock) or KLF4 overexpression group. b Representative images of western blot for the expression of KLF4, E-selectin, VCAM-1, ICAM-1, p-NF-kappaB, Claudin-5, and ZO-1 in the bEnd3 cells of mock and KLF4 overexpression group at 12 h restoration of OGD or NO-OGD/R. c - i Densitometric analysis shows the ratios of KLF4/beta-actin ( c ), E-selectin/beta-actin ( d ), VCAM-1/beta-actin ( e ), ICAM-1/beta-actin ( f ), phosphorylated NF-kappaB/total NF-kappaB ( g ), Claudin-5/beta-actin ( h ), and ZO-1/beta-actin ( i ). NO-OGD/R mock-treated cells served as control. Data represent mean +- standard deviation and were analyzed by two-way ANOVA ( n = 5 per experimental group). Note that the expressions of three cell adhesion molecules including E-selectin, VCAM-1, and ICAM-1 and the phosphorylation of NF-kappaB on mock-treated bEnd3 cells were significantly induced in response to OGD/R, but the expression of Claudin-5 and ZO-1 markedly decreased compared to that of the NO-OGD/R mock-treated controls. However, these effects were significantly rescued by overexpressing the levels of KLF4 in the bEnd3 cells. * P < 0.05, ** P < 0.01, *** P < 0.001; ns, not significant
