Clinical relevance of cZNF609 dysregulation in vascular disease (A) Human retinal endothelial cells were transfected with scrambled siRNA (Scr), cZNF609 siRNA, or left untreated (Ctrl) for 48 h. qRT-PCRs were conducted to detect cZNF609 expression (n=4, *P<0.05). (B) Cell viability was determined by MTT assay. Result was shown as relative change compared with Ctrl group (n=4, *P<0.05). (C) Cell proliferation was detected by EdU detection kit (n=4, *P<0.05). Scale bar, 200 μm. (D) Transwell assay and quantification analysis was used to detect cell migration (n=4, *P<0.05). Scale bar, 20 μm. (E) Human retinal endothelial cells were seeded on the matrigel matrix. Tube-like structures were observed 24 h after cell seeding. Average length of tube formation for each field was statistically analyzed (n=4, *P<0.05). Scale bar, 100 μm. (F) qRT-PCRs were performed to detect cZNF609 expression in the fibrovascular membranes of diabetic patients (n=15) and idiopathic epiretinal membranes of non-diabetic patients (n=10) (*P<0.05 versus non-diabetic controls). (G) qRT-PCRs were conducted to detect cZNF609 expression in EDTA-plasma obtained from diabetic patients (n=30) and non-diabetic controls (n=30) (*P<0.05 versus non-diabetic controls). (H) cZNF609 expression in EDTA-plasma obtained from the patients with CAD (n=15) and healthy volunteers (HC; n=10) was determined by qRT-PCRs. (I) cZNF609 expression in EDTA-plasma obtained from patients with hypertension (n=30) and healthy volunteers (HC; n=30) was determined by qRT-PCRs.
