Effect of zinc chelator TPEN on gene expression of retinal ganglion cells during optic nerve injury

ABSTRACT: Retinal ganglion cells (RGCs) convey the major output of information collected from the eye to the brain. RGCs are irreversibly lost when injured in degenerative diseases such as glaucoma; this failure can be partially reversed by eliminating the retinal mobile zinc (Zn2+) and leads to substantial axon regeneration. Here, we conducted an mRNA sequencing of flow cytometry-isolated RGCs 3 days after optic nerve injury (NC) with or without TPEN treatment. We identified differentially expressed genes using a cutoff of at least 1.5-fold change and FDR of at least 0.05. We focused on the intersecting genes that were upregulated after NC and recovered in TPEN (TPEN/NC; fold change < -1.5; P < 0.05), namely, TPEN target genes.
