HIF1AN and fungal keratitis: As shown in Table 1, the average ratios of the expression levels of the Hmox1, Nos3, Hif1a, Sod2, Sod3, and Gpx2 genes increased more than 2-fold (p < 0.05) at day 1 p.i. in the fungal keratitis model, whereas the expression ratios of the Hif1an and Prdx6 genes decreased more than 2-fold (p < 0.05).
