The expression of FSCN1 in primary choroidal endothelial cells from laser-induced choroidal neovascularization (CNV) mice and age/sex-matched control (WT) mice was determined using a qRT-PCR assay, which revealed a ~ 8.15-fold upregulation of FSCN1 mRNA levels in the CNV group compared to the WT group (Fig. 2C). Here, FSCN1 is linked to choroidal neovascularization.
