The expression of five key genes in patients with the POAG group and participants in the normal group. A KRT14 is downregulated in patients with POAG. B HBB is upregulated in patients with POAG. C ACOX2 is upregulated in POAG. D HEPH is upregulated in POAG. E KRT13 is downregulated in patients with POAG. P value < 0.05. Red represents normal groups, and green represents POAG groups. Keratin 14, KRT14; Hemoglobin subunit beta, HBB; Acyl-CoA Oxidase 2, ACOX2; Hephaestin, HEPH; and Keratin 13, KRT13
