Figure Lengend Snippet: Abundance of proteins significantly associated with incomplete response to anti-VEGF therapy. A total of 10 proteins were found to be significantly regulated in substantial edema versus no edema. A, Upregulated proteins determined by mass spectrometry at time points 1 to 3 (T1-T3) included afamin (AFM), alpha-1B-glycoprotein (A1BG), and angiotensinogen (AGT). B, Downregulated proteins included cystatin-C (CST3), clusterin (CLU), apolipoprotein E (APOE), epidermal growth factor-containing fibulin-like extracellular matrix protein (EFEMP1), Ig lambda chain V-I (IGLV1), latent transforming growth factor beta-binding protein 2 (LTBP2), and reelin (RELN). C, The increased level of afamin was confirmed by ELISA. D, VEGFA concentration assessed by ELISA. There was no significant difference in VEGFA between the substantial edema and no edema groups. Box plots indicate median, min and max and first and third quartiles. ∗ P < 0.05; ∗∗ P < 0.01; ∗∗∗ P < 0.001. ELISA = enzyme-linked immunosorbent assay; LFQ = Label-Free Quantification.
Article Snippet: Samples were diluted 500-fold for afamin (ELH-AFM-1, RayBiotech) and 2-fold for VEGFA (DVE00, R&D Systems).
