(Submitter supplied) We report the genome-wide RNA sequencing changes to isolated retinal ganglion cells (RGCs) from immunopanned embryonic day 18 (E18) and early postnatal (P5) wildtype mouse retinas. We report the transcriptomic change associated with RGCs in a survival and regenerative state, and use gene-set enrichment analysis (GSEA) to predict the upstream transcription factors likely regulating these observed changes.

(Submitter supplied) Nuclear factor erythroid 2 like (Nfe2l) gene family members 1-3 mediate cellular response to oxidative stress, including in the central nervous system (CNS). However, neuronal functions of Nfe2l3 are unknown. Here, we comparatively evaluated expression of Nfe2l1, Nfe2l2, and Nfe2l3 in singe cell RNA-seq (scRNA-seq)-profiled cortical and retinal ganglion cell (RGC) CNS projection neurons, investigated whether Nfe2l3 regulates neuroprotection and axon regeneration after CNS injury in vivo, and characterized a gene network associated with Nfe2l3 in neurons. more...

(Submitter supplied) Collapsin response mediator proteins (Crmps) play roles in neuronal development and axon growth. However, neuronal-specific roles of Crmp1, Crmp4, and Crmp5 in regeneration of injured central nervous system (CNS) axons in vivo are unclear. Here, we analyzed developmental and subtype-specific expression of Crmp genes in retinal ganglion cells (RGCs), tested whether overexpressing Crmp1, Crmp4, or Crmp5 in RGCs through localized intralocular AAV2 delivery promotes axon regeneration after optic nerve injury in vivo, and characterized developmental co-regulation of gene-concept networks associated with Crmps. more...

(Submitter supplied) Expressing HDAC5 mutant whose serine 259 and 488 have been replaced by alanine (HDAC5AA) promotes optic nerve regeneration in retinal ganglion cells. However, expressing GFP, HDAC5WT and HDAC5DAD, whose serine 259 and 498 have been replaced by aspartic acid and serine 280 by alanine, do not promote optic nerve regeneration. The goal of this experiment was to determine the underlying mechanisms leading to the phenotypical differences in optic nerve regeneration between control GFP, HDAC5DAD, and HDAC5AA by analyzing the retinal transcriptome of the different treatments.

(Submitter supplied) Adult mammalian CNS neurons undergo a developmental switch in intrinsic axon growth ability associated with their failure to regenerate axons after injury. Krüppel-like transcription factors (KLF) regulate intrinsic axon growth ability, but signaling regulation upstream and downstream is poorly understood. Here we find that suppressing expression of KLF9, an axon growth suppressor normally upregulated 250-fold in retinal ganglion cell (RGC) development, promotes long-distance optic nerve regeneration in vivo. more...

(Submitter supplied) CNS neurons lose their ability to grow and regenerate axons during development. This is the case for Retinal Ganglion Cells (RGCs) in the retina, which transmit visual information to the brain via axons projecting into the optic nerve. RGCs are unable to regenerate their axon after injury, and start a degeneration process that leads to cell death and loss of vision. To identifying molecular mechanisms that increase regeneration of RGC and may offer new treatment strategies for patients with glaucoma or other types of optic neuropathies, we focused on the identification of transcription factors and chromatin accessible sites that are enriched in RGC during developmental stages, in which axon growth capacity is robust. more...

(Submitter supplied) Neurons of the central nervous system (CNS) display only a limited ability to survive and regenerate their axons after an injury. In mice, 85% of retinal ganglion cells (RGCs) die within 2 weeks of axotomy by optic nerve crush (ONC) and only few survivors regenerate axons. In the past years, a multitude of interventions have been identified to improve RGC survival and regeneration after an injury, however, each only protects a subset of neurons and stimulates axon regrowth in an even smaller set.. more...

(Submitter supplied) The failure of adult CNS neurons to survive and regenerate their axons after injury or in neurodegenerative disease remains a major target for basic and clinical neuroscience. Recent data demonstrated in the adult mouse that exogenous expression of Sry-related high-mobility-box 11 (Sox11) promotes optic nerve regeneration after optic nerve injury, but exacerbates the death of a subset of retinal ganglion cells, alpha-RGCs. more...

(Submitter supplied) The central nervous system (CNS) projection neurons fail to spontaneously regenerate injured axons. Targeting the developmentally regulated genes in order to reactivate embryonic intrinsic axon growth capacity, or targeting tumor suppressor genes such as Pten, promote axon regeneration in a subset of injured retinal ganglion cells (RGCs). The subset of RGCs that regenerate axons in response to inhibition of Pten was narrowed-down to the Opn4+ intrinsically photosensitive (ip) and α subtypes of RGCs. more...

(Submitter supplied) A formidable challenge in neural repair in the adult central nervous system (CNS) is the long distances that regenerating axons often need to travel in order to reconnect with their targets. Thus, a sustained capacity for axon regeneration is critical for achieving functional restoration. Although deletion of either Phosphatase and tensin homolog (PTEN), a negative regulator of mammalian target of rapamycin (mTOR), or suppressor of cytokine signaling 3 (SOCS3), a negative regulator of Janus kinase/signal transducers and activators of transcription (JAK/STAT) pathway, in adult retinal ganglion cells (RGCs) individually promoted significant optic nerve regeneration, such regrowth tapered off around two weeks after the crush injury. more...

(Submitter supplied) Axon regeneration holds great promise for neural repair of CNS axonopathies, including glaucoma. Pten deletion in retinal ganglion cell (RGC) promotes potent optic nerve regeneration, but only a small population of Pten-null RGCs are actually regenerating RGCs (regRGCs); most surviving RGCs (surRGCs) remain non-regenerative. Here we developed a strategy to specifically label and purify regRGCs and surRGCs respectively from the same Pten deletion mice after optic nerve crush, in which they differ only in their regeneration capability. more...
