| Outline of Final Research Achievements |
We previously investigated whether the estrogen receptor beta (ESR2) gene single nucleotide polymorphisms (SNPs) were associated with primary open-angle glaucoma (POAG), and our findings demonstrated a higher frequency of the ESR2 gene SNPs in female patients with POAG in comparison to control subjects, and the maximum intraocular pressure (IOP) in female patients with the risk allele was significantly higher than that in female patients without the risk allele. To elucidate the molecular mechanisms of IOP regulation (elevation) and evaluate the possibility of ESR2 knockout mice as a POAG model, the IOP and optic nerve damage of ESR2 knockout mice were investigated. There was no statistically significant IOP difference (P>0.05) between ESR2 knockout and control (wild type) mice. The retinal thickness and retinal ganglion cells of ESR2 knockout and control mice has been measured and will be counted to evaluate the optic nerve damage.
