To determine whether Ucp2 expression is positively or negatively related to the progression of glaucoma, we analyzed publically available data from a microarray that determined gene expression changes in the retina and optic nerve heads of 10.5 month old DBA/2J mice and DBA/2J; Gpnmb+ controls (Howell et al., 2014). The gene discussed is UCP2; the disease is glaucoma.
