Labeled quantitative proteomics dataset of optogenetics induced axon regeneration

ABSTRACT: This labeled quantitative proteomics dataset was collected from a transgenic channel rhodopsin mouse model (Chr2) subjected to light stimulation after traumatic optic nerve crush (ONC) was performed. Mouse models expressing channel rhodopsin were subjected to therapeutic light stimulation promoting axon regeneration of retinal ganglion cell (RGC) axons post optic nerve crush. Experimental mice and wild type control mice were euthanized, and optic nerves were collected. A protein extraction was carried out by careful mincing of the tissue in extraction buffer (TEAB, NaCl and SDS). Protein amount normalization across samples was achieved using dot blot densitometry using ImageJ software. Samples were labelled using a modified 16plex TMT (Tandem Mass Tag) kit for quantification after overnight trypsin digestion. Untargeted liquid chromatography-mass spectrometry was performed on an Easy-nLC 1000 liquid chromatograph coupled to a QExactive mass spectrometer (LC-MS/MS). Data analysis was performed using Proteome Discoverer 2.5.
