Amacrine cells suppress retinal ganglion cells survival and optic nerve regeneration bu releasing intersynaptic zinc

Project description: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. ZnT3 conditional knockout in retinal amacrine cells blocks the synaptic transport of Zn2+, which promotes RGC survival and axonal regeneration in optic nerve jinjury (ONC). Here, we conducted an mRNA sequencing of flow cytometry-isolated RGCs 3 days after optic nerve injury with or without ZnT3 expression in retinal amacrine cells.

Transcription profiling of mouse developing retinal ganglion and amacrine cells reveals molecular heterogeneity of

Project description:During development of the central nervous system (CNS), cycling uncommitted progenitor cells give rise to a variety of distinct neuronal and glial cell types. As these different cell types are born, they progress from newly specified cells to fully differentiated neurons and glia. In order to define the developmental processes of individual cell types, single cell expression profiling was carried out on developing ganglion and amacrine cells of the murine retina. Individual cells from multiple developmental stages were isolated and profiled on Affymetrix oligonucleotide arrays. These experiments have yielded an expanded view of the processes underway in developing retinal ganglion and amacrine cells, as well as several hundred new marker genes for these cell types. In addition, this study has allowed for the definition of some of the molecular heterogeneity both between developing ganglion and amacrine cells and among subclasses of each cell type. Experiment Overall Design: Single retinal cells were isolated in tubes containing lysis buffer, their mRNAs were reverse transcribed, and the resulting cDNAs were PCR amplified for 35 cycles. Labeled cDNA samples were hybridized to Affymetrix 430 2.0 microarrays and the data was normalized using MAS5.0 software. Cells were identified post hoc as either developing retinal ganglion cells, amacrine cells or rod photoreceptor cells.

Transcriptional profiling of adult retinal ganglion cells during optic nerve regeneration

Project description:Objective: To identify genes that are differentially expressed in retinal ganglion cells undergoing axon regeneration after optic nerve injury. Adult mice that express cyan-fluorescent protein (CFP) in RGCs were treated with pro-regenerative treatment after optic nerve injury. The treated RGCs were selected by FACS (CFP+mcherry) and their RNA profiles were analyzed.

Single nuclei RNA-seq analysis of control and Dnmt3a conditional knockout (cKO) of retinal ganglion cells at 2 days post optic nerve crush.

Project description:Dnmt3a deficiency in retinal ganglion cells promotes axon regeneration in an optic nerve crush mouse model. To investigate the role of Dnmt3a in axon regeneration, retinal ganglion cell nuclei were sorted from control and retinal ganglion cell-specific Dnmt3a knockout mice at 2 days post optic nerve crush and applied for single nuclei RNA-seq analysis by 10X Genomics technology.

Differential response of C57BL/6J mouse and DBA/2J mouse to optic nerve crush

Project description:Retinal ganglion cell (RGC) death is the final consequence of many blinding diseases, where there is considerable variation in the time course and severity of RGC loss. Indeed, this process appears to be influenced by a wide variety of genetic and environmental factors. In this study we explored the genetic basis for differences in ganglion cell death in two inbred strains of mice. We found that RGCs are more susceptible to death following optic nerve crush in C57BL/6J mice (54% survival) than in DBA2/J mice (62% survival). Using the Illumina Mouse-6 microarray, we identified 1,580 genes with significant change in expression following optic nerve crush in these two strains of mice. Our analysis of the changes occurring after optic nerve crush demonstrated that the greatest amount of change (44% of the variance) was due to the injury itself. This included changes associated with ganglion cell death, reactive gliosis, and abortive regeneration. The second pattern of gene changes (23% of the variance) was primarily related to differences in gene expressions observed between the C57BL/6J and DBA/2J mouse strains. The remaining changes in gene expression represent interactions between the effects of optic nerve crush and the genetic background of the mouse. We extracted one genetic network from this dataset that appears to be related to tissue remodeling. One of the most intriguing sets of changes included members of the crystallin family of genes, which may represent a signature of pathways modulating the susceptibility of cells to death. Differential responses to optic nerve crush between two widely used strains of mice were used to define molecular networks associated with ganglion cell death and reactive gliosis. These results form the basis for our continuing interest in the modifiers of retinal injury. 18 Samples: 9 per strain (C57BL/6J & DBA/2J); 3 conditions per strain
