There were eight genes that were upregulated (i.e., AFAP1, COL4A1, CPXM1, ETS1, PRKAG2, PTPN1, SH2B3, and TES), and nine that were downregulated (i.e., ANGPTL2, ANTXR1, HHEX, LTBP2, MAFB, ME3, NR1H3, PCSK5, and PRSS23) in POAG-affected SC cells (Table 2). This evidence concerns the gene PRSS23 and open-angle glaucoma.
