Figure 3. Significant more genes regulated in the inferior than the superior retina after hyperoxia. According to the different selection criteria, the number of genes and non-coding RNAs regulated by hyperoxia were assessed and separately elucidated for the superior and inferior regions. Fold ratio (FR) values < 0.5 indicate significant downregulation of expression (at least halved); FR values > 2 indicate significant upregulation of expression (more than doubled).
