Gene therapy for ocular hypertension using hfCas13d-mediated mRNA targeting.

ABSTRACT: Glaucoma is a major global cause of irreversible vision loss. It is marked by elevated intraocular pressure (IOP) and the loss of retinal ganglion cells (RGC). While there are medical and surgical therapies for glaucoma aiming to reduce aqueous humor production or enhance its drainage, these treatments are often inadequate for effectively managing the disease. In this study, we developed a targeted therapy for glaucoma by knocking down two genes associated with aqueous humor production (aquaporin 1 [AQP1] and carbonic anhydrase type 2 [CA2]) using Cas13 RNA editing systems. We demonstrate that hfCas13d-mediated knockdown of AQP1 and CA2 significantly lowers IOP in wild-type mice and in a corticosteroid-induced glaucoma mouse model. We show that the lowered IOP r
