Figure Lengend Snippet: Expression levels of hyaluronidase (Hyal)-1 (A) , CD44 (B) and receptor for hyaluronan-mediated motility (RHAMM) (C) in the retinal lysates of non-diabetic control rats (C) (n=12) and diabetic rats (D) (n=12) were determined by Western blot analysis. After determination of the intensity of the protein bands, intensities were adjusted to those of β-actin in the samples. Oxidative stress was monitored with the use of 2’,7’-Dichlorofluorescein (DCF) fluorescence intensity analysis (D) . Results are expressed as mean ± standard deviation. Ultra-Low molecular weight hyaluronan (ULMW-HA) induces breakdown of blood-retinal barrier (E) . ULMW-HA was injected intravitreally at the dose of 50 ng in 5 µL in one eye and the same volume of phosphate-buffered saline (PBS) was injected in the contralateral eye of normal rats. The BRB was quantified with the fluorescein isothiocyanate-conjugated dextran technique. Results are expressed as mean ± standard deviation of 12 rats. *p < 0.05 compared to the values obtained from PBS-injected eyes. (independent t-test). Western blot analysis of retinas demonstrated that intravitreal injection of ULMW-HA induced significant upregulation of the expression of phospho-NF-κB (F) , phospho-ERK1/2 (G) , vascular endothelial growth factor (VEGF) (H) , intercellular adhesion molecule-1 (ICAM-1) (I) , vascular cell adhesion molecule-1 (VCAM-1) (J) and high-mobility group box-1 (HMGB1) (K) . Results are expressed as mean ± standard deviation or standard error of mean of 8–10 rats in each group (*p < 0.05; independent t-test).

Article Snippet: To determine the presence of Hyal-1, Hyal-2, HAS2, CD44, syndecan-1, heparan sulphate and RHAMM in the vitreous samples, equal volumes (10 μL) of vitreous samples were boiled in Laemmli’s sample buffer (1:1, v/v) under reducing condition for 10 min. Immunodetection was performed with the use of rabbit polyclonal anti-Hyal-1 antibody (1:1000, NBP2-16906, Novus Biologicals), mouse polyclonal anti-Hyal-2 antibody (1:1000, H00008692-B02P, Novus Biologicals), mouse monoclonal anti-HAS2 antibody (1:1000, ab140671, Abcam), rabbit monoclonal anti-CD44 antibody (1:1000, ab189524, Abcam), rabbit monoclonal anti-RHAMM antibody (1:1000, ab124729, Abcam), rabbit monoclonal anti-phospho-extracellular signal-regulated kinase (ERK)1/2 antibody (1:1000, MAB1018, R&D Systems), rabbit polyclonal anti-p65 subunit of nuclear factor-kappa B (phospho-NF-κB) (1:1000, NB100-82086, Novus Biologicals), rabbit polyclonal anti-high-mobility group box1 (HMGB1) (1:1000, Cat. no. ab18256, Abcam), mouse monoclonal anti-VEGF antibody (1:750, MAB293, R&D Systems), mouse monoclonal anti-intercellular adhesion molecule-1 (ICAM-1) antibody (1:100, sc-8439, Santa Cruz Biotechnology Inc.), and mouse monoclonal anti-vascular cell adhesion molecule-1 (VCAM-1) antibody (1:100, sc-13160, Santa Cruz Biotechnology Inc.).

Figure Lengend Snippet: Human retinal microvascular endothelial cells (HRMECs) were left untreated or stimulated with tumor necrosis factor-α (TNF-α) (5 ng/mL) for 24 h with or without apigenin (10 µg/mL). Protein expression of intercellular adhesion molecule-1 (ICAM-1) (A) and vascular cell adhesion molecule-1 (VCAM-1) (B) was determined by Western blot analysis. Adhesion of fluorescently labeled THP-1 monocytic cells to HRMECs monolayer was quantified (C) . Results are expressed as mean ± standard deviation or standard error of mean from three different experiments each performed in triplicate. One-way ANOVA and independent t-test were used for comparisons between three groups and two groups, respectively. *p < 0.05 compared with values obtained from untreated cells. #p < 0.05 compared with values obtained from cells treated with TNF-α (RFU = relative fluorescence unit).
