Effects of Aberrant Pax6 Gene Dosage on Mouse Corneal Pathophysiology and Corneal Epithelial Homeostasis [PDF]

, 2011
Background: Altered dosage of the transcription factor PAX6 causes multiple human eye pathophysiologies. PAX6(+/-) heterozygotes suffer from aniridia and aniridia-related keratopathy (ARK), a corneal deterioration that probably involves a limbal ...
