Targeting AKT via SC79 for Photoreceptor Preservation in Retinitis Pigmentosa Mouse Models.

ABSTRACT: Background/Objectives: Retinitis pigmentosa is a degenerative retinal disease and a major cause of inherited blindness globally. The pro-survival kinase AKT is downregulated in degenerating photoreceptors in retinitis pigmentosa, and its activation has shown neuroprotective effects in retinitis pigmentosa and other neurodegenerative disorders. In this study, we evaluated the therapeutic potential of SC79, a pharmaceutical AKT activator, in two mouse models of retinitis pigmentosa, rd1.GFP and RhoP23H.GFP. Methods: SC79 was administered intravitreally at postnatal day 12 (P12) and analysis was conducted at P16. Results: SC79 at 10 µM was well tolerated in wildtype mice, with no reduction in retinal function or thickness. In rd1.GFP mice, SC79 partia
