Retinitis pigmentosa (RP) mouse cone transcriptom change with Txnip treatment
Purpose: To identifiy mRNA changes in retinitis pigmentosa (RP) cone photoreceptors with Txnip overexpression treatment, which improved RP cone survival and visual acuity. Methods: two RP mouse strains, rd1 and Rho-/-, were injected with AAV-Txnip or AAV-H2BGFP control subretinally at P0. Retinas were dissected out at P21 for rd1 and P90 for Rho-/-. 1,000 H2BGFP labeled cones per retina sample were FACS sorted out, and subject for RNA-sequencing. Results: >1,400 genes in P21 rd1 and >700 genes in Rho-/-  were found differentially expressed with Txnip treatment. Conclusions: 25 genes are in common between P21 rd1 and P90 Rho-/- with Txnip treatment. On this list, notably, three mitochondrial Electron Transport Chain (ETC) genes were up-regulated. Overall design: Cone photoreceptor mRNA profiles of 21-day old rd1 and 90-day old Rho-/- mice  with or without AAV-Txnip treatment.
