Figure 3. Upregulation of ANGPTL4 in patients with DME.
(A and B) Levels of ANGPTL4 in aqueous samples from nondiabetic (control) patients and diabetic patients with DME who have not previously received anti-VEGF therapy or have not received anti-VEGF therapy for 12 weeks or longer in the sample eye (see Supplemental Table 2) (A) and its correlation with EC permeability. r = –0.8; P < 0.0001 (B). (C and D) ANGPTL4 (C) and VEGF (D) protein levels in DME patients without previous treatment with anti-VEGF therapy (DME Untx) or DME patients who have received a single treatment with anti-VEGF therapy in the sample eye within 6 weeks of sample collection (DME Tx) compared with nondiabetic (control) patients. Mann-Whitney U test (A), Pearson correlation (B), or 1-way ANOVA (C and D). *P < 0.05; **P < 0.01; ****P < 0.0001.
