Combined Jun and Ddit3 deficiency does not attenuate loss of RGCs after NMDA insult. (A) Representative images showing TUJ1 immunolabeled cells in the GCL of Jun and Ddit3 deficient (Jun^fl/flDdit3^−/−; Six3-cre⁺) mice 7 days after intravitreal NMDA or PBS injection. Significant RGC loss occurred in wildtype (Jun^+/?Ddit3^+/?; Six3-cre⁻) as well as Jun and Ddit3 deficient mice after NMDA insult (n = 3 for PBS WT, n = 3 for NMDA WT, n = 4 for PBS Jun^+/?Ddit3^+/?; Six3-cre⁻, n = 5 for NMDA Jun^+/?Ddit3^+/?; Six3-cre⁻). (B) Quantification of TUJ1+ RGCs confirmed that Jun and Ddit3 deficient mice had a similar loss of RGCs compared to wildtype mice 7d after NMDA injection (*p < 0.001 comparing PBS to NMDA; p = 0.8582 between WT and Jun^fl/flDdit3^−/−; Six3-cre⁺ NMDA, ns between genotypes). Scale bar: 50 μm.
