Inherited retinal degenerative diseases (IRD) are a group of disorders that lead to progressive deterioration of mainly the photoreceptors. Retinitis pigmentosa (RP) and cone-rod dystrophy (CRD) are two forms of IRDs. RP is the most common form of IRD and is due to rod photoreceptor degeneration followed by cone photoreceptor loss. CRD, on the other hand, is characterized by the loss of cones or the concurrent degeneration of both cones and rods. Both RP and CRD are presently incurable. More than 200 genes have been identified to cause IRDs and the functions of many of these genes remain unclear. Mutations in a novel gene, C8ORF37, were identified to cause recessive, severe, and early-onset RP and CRD. I, therefore, pioneered in characterizing the role of C8ORF37 in the retina.

520 $a Inherited retinal degenerative diseases (IRD) are a group of disorders that lead to progressive deterioration of mainly the photoreceptors. Retinitis pigmentosa (RP) and cone-rod dystrophy (CRD) are two forms of IRDs. RP is the most common form of IRD and is due to rod photoreceptor degeneration followed by cone photoreceptor loss. CRD, on the other hand, is characterized by the loss of cones or the concurrent degeneration of both cones and rods. Both RP and CRD are presently incurable. More than 200 genes have been identified to cause IRDs and the functions of many of these genes remain unclear. Mutations in a novel gene, C8ORF37, were identified to cause recessive, severe, and early-onset RP and CRD. I, therefore, pioneered in characterizing the role of C8ORF37 in the retina.
520 $a This dissertation is comprised of four chapters that is organized as follows: (1) summary of an ocular disorder (2) a genetic model of a retinal disorder (3) biochemical/proteomic analysis of C8ORF37 (4) potential clinical applications. A summary of ocular disorders is discussed in Chapter 1, with an emphasis on CRD. Chapter 2 focuses on the generation and characterization of C8orf37 mutant mouse models that recapitulate the retinal pathologies observed in human patients. In C8orf37 knockout retinas, the outer segment (OS) was nonuniform, swollen, and wider in width when compared to the controls. Moreover, many OS membrane proteins were reduced in the retina of C8orf37 knockout, including CNGB1 and RDS, proteins essential for OS disc morphogenesis and alignment. Our findings shed new light on the pathogenesis underlying retinal dysfunction and degeneration in C8ORF37-deficient patients.
520 $a To determine the function of a novel protein, a powerful approach is by identifying its binding partners. In Chapter 3, I discuss GST pull-down using bovine retinal lysates, yeast-two-hybrid, and immunoprecipitation with mouse retinal lysate in order to identify C8ORF37-interacting proteins. Our pull-downs identified KTN1, RAB28, UCHL1, and PSMD14 suggesting that C8ORF37 may have a role in protein homeostasis.
520 $a Chapter 4 concludes and discusses the impact of generating and characterizing C8orf37 animal models for future studies in understanding photoreceptor function and in the development of therapeutics against retinal degeneration.
