Purpose

The S100A protein family is involved in various inflammatory processes. Two of its members, S100A4 and A13, are thought to be pro-angiogenic in tumor development. This study examines whether S100A proteins are involved in the pathogenesis of inflammation-associated corneal neovascularization (CorNV).

Methods

We used 10–0 nylon suture-(S) or chemical burn (CB)-induced CorNV models for a microarray analysis of the genome-wide expression pattern. At different time points after suturing, we conducted histopathological examinations to detect the infiltration of inflammatory cells into the corneal stroma. Representative members of the S100A family (S100A4, S100A6, S100A8, S100A9, and S100A13), pro-inflammatory cytokines (IL-1β, IL-6, transforming growth factor β1, and MIP-2), and pro-angiogenic factors (fibroblast growth factor and vascular endothelial growth factor) were detected with …
