Gene expression data on human optic nerve head astrocytes in normal Caucasian and African americans

To determine whether optic nerve head astrocytes, a key cellular component of glaucomatous neuropathy, exhibit differential gene expression in primary culture of astrocytes from normal African American donors, compared to astrocytes from normal Caucasian American donors. All donors have no histories of eye disease, diabetes, or chronic CNS disease. Keywords: Gene expression profile We divided samples into two groups: normal Caucasian American and normal African American. We analyzed data from Affymetrix Human Genome Human Genome U133A and U133A 2.0 chips.
