Figure 1. HIF-1α and its target genesexpression in post- I/R retina.

(A) Western blots show retinal HIF-1α expression is increased and maintained 6 h after I/R injury. (B) Hif-1 α and its representative target genes were upregulated in post-I/R retina detected by qPCR (n = 5). Gapdh was used as the internal control. Error bars indicate the standard error. Cont; control. **p < 0.01, Mann-Whitney’s U test.
