The focus of our research centers on exploring the proteome changes and corresponding signaling pathways involved in the development of diabetic cataract, age-related cataract and post-vitrectomy cataract, investigating aqueous humor, anterior capsule and lens human samples. Outstanding proteomic profiles of the three sample types have been generated using DIA proteomics. We have observed substantial differences in the regulation of several pathways between our groups and samples types, and we have particularly highlighted the involvement of non-canonical Wnt receptor signaling pathway, glycosaminoglycan and glycosphingolipid pathways, and oxidation reduction pathway in the formation of different cataract forms.
