Combined retinal proteome datasets in response to atropine treatment using iTRAQ and SWATH-MS based proteomics approaches in guinea pig myopia model.

ABSTRACT: Atropine, a non-selective muscarinic antagonist, is known to slow down myopia progression in human adolescents and in several animal models. However, its underlying molecular mechanism is unclear. The present work built a monocular form-deprivation myopia (FDM) guinea pig model, using facemasks as well as atropine treatment on FDM eyes for 2 and 4 weeks. Retinal protein changes in response to the FDM and effects of topical administration of atropine were screened for the two periods using fractionated isobaric tags for a relative and absolute quantification (iTRAQ) approach coupled with nano-liquid chromatography-tandem mass spectrometry (nano-LC-MS/MS) (n=24, 48 eyes). Retinal tissues from another cohort receiving 4-weeks FDM with atropine treatment (n=12, 24 eyes) with more
