showed that up-regulation of TGF-β and VEGF in conjunctival biopsies of glaucoma patients was highly correlated with surgical failure, whereas up-regulation of other factors [e.g. interleukin (IL)-6, IL-8, matrix metalloproteinase (MMP)-1, MMP-2, etc.] were associated with surgical success 8. The gene discussed is VEGFA; the disease is glaucoma.
