Expression of the ETS transcription factor ELF3 in the retinal pigment epithelium

Abstract

Purpose. The ETS family of transcription factors regulate several critical cellular functions. They have also been implicated in invertebrate ocular development. This work was undertaken to determine whether epithelium-specific ETS transcription factors are expressed in the retinal pigment epithelium and to investigate the possible role of these factors in retinal diseases such as age-related macular degeneration. Methods. The expression of the epithelial ETS transcription factors ELF5, ESE3, and ELF3 was assessed by RT-PCR in the human RPE cell lines D407 and hTERT-RPE1. The full-length coding sequence of rat Elf3 was isolated with 3′ rapid amplification of cDNA ends (RACE) and degenerative..
