Identification of the cornea-specific keratin 12 promoter by in vivo particle-mediated gene transfer.

Abstract

The particle-mediated gene transfer is a suitable technique for in vivo delivery of transgenes to corneal epithelial cells. The 2.5-kb DNA fragment 5'-flanking Krt1.12 contains corneal epithelial cell-specific regulatory cis-DNA elements. Pax-6 is a positive transcription factor essential for keratin 12 expression.
