Figure 4. ADAMTS13 expression levels in diabetic rat retinas and effects of exogenously administered ADAMTS13. ADAMTS13 expression levels in the retinal lysates of diabetic rats (D) (n = 12) and nondiabetic control animals (n = 12) were determined by western blot analysis. After the measurement of the intensities of ADAMTS13 proteoform bands, the immunoblots were stripped and reprobed to evaluate ß-tubulin intensities in all sample panels (A). Results are expressed as means ± standard deviation of the ratios between ADAMTS13 and ß-tubulin (* p < 0.05; independent t-test). The effects of intravitreal ADAMTS13 injection on vascular permeability and markers of hemostasis and inflammation in rat retinas after streptozotocin-induced diabetes were evaluated by quantifications of the BRB breakdown by detection of FITC dextran seeped into the retina after the systemic injection (B). Retinal protein expression levels of the von Willebrand factor (VWF) (C), the platelet marker CD41 (D), vascular endothelial (VE)-cadherin (E), and ß-catenin (F) were determined by immunoblot analysis. Statistical comparisons (mean ± standard deviation of 8–10 rats) were performed as described in Section 2.12. * p < 0.05 compared with values obtained from nondiabetic controls. # p < 0.05 compared with values obtained from diabetic rats.

Figure 5. Intravitreal administration of ADAMTS13 reduces retinal inflammation in diabetic rats. The relative protein amounts of phospho-ERK1/2 (A), high-mobility group box-1 (HMGB1) (B), vascular cell adhesion molecule-1 (VCAM-1) (C), and intercellular adhesion molecule-1 (ICAM-1) (D) were determined in rat retinas with the use of western blots. The animals were made diabetic with the use of a single streptozotocin bolus, ADAMTS13 was injected in the vitreous, and its effects on inflammation markers were evaluated by comparison of ADAMTS13-injected with the contralateral PBS-injected eyes in single animals. Statistical comparisons (mean standard deviation of 8–10 rats in each group) were performed as described in Section 2.12. * p < 0.05 compared with nondiabetic controls. # p < 0.05 compared with diabetic rats.

Figure 6. Regulation of proangiogenic and inflammatory molecule expression by ADAMTS13 in human retinal Müller glial cells. Human glial cells were left untreated or treated with high glucose (HG) (25 mM), tumor necrosis factor-α (TNF-α) (1 ng/mL), or cobalt chloride (CoCl2) (300 µM) for 24 h or ADAMTS13 (100 ng/mL) for 1h followed by HG, CoCl2, or TNF-α. A total of 25 mM of mannitol was used as an inert control for osmotic effects by HG treatment. Levels of monocyte chemotactic protein-1 (MCP-1), matrix metalloproteinase-9 (MMP-9), and vascular endothelial growth factor (VEGF) were quantified in the culture media by ELISA. The present data were generated from three different experiments, each performed in triplicates, and the results are provided as means ± standard deviation; statistical comparisons were performed as described in Section 2.12. * p < 0.05 indicates the comparisons with values obtained from control cells. # p < 0.05 documents the differences with values obtained from cells treated with HG, TNF-α, or CoCl2.

Figure 11. Inhibition of endothelial cell migration by ADAMTS13. (A,B) Confluent monolayers of overnight starved HRMECs were scratched with sterile micropipette tips and monolayer regeneration was microscopically monitored, subject to various treatments. In one set of experiments, the cultures were pretreated with a dilution medium or ADAMTS13 (60, 200, or 600 ng/mL) for 1 h, followed by stimulation with vascular endothelial growth factor (VEGF) (10 ng/mL) for 16 h. Two independent experiments were performed in duplicates and two-to-three independent field images were taken for the migration analysis with the Image J software (summarized in (B)). In panel (A), representative images illustrate the effect of ADAMTS13, at a dose of 600 ng/mL, on VEGF-induced cell migration. (C) In a second set of experiments, endothelial cell migration through 8 µm pores of polyethylene terephthalate (PET) membranes in response to VEGF (10 ng/mL) with or without pretreatment with ADAMTS13 (6 to 600 ng/mL) was analyzed with the xCELLigence instrument (three or four independent experiments in duplicates).
