Genetic Approach to Retinal Vascular Disease

Development of novel molecular biology techniques in the 1970s and 1980s furnished scientists with new tools to advance the study and treatment of human disease. Progress in the understanding of bacterial and viral biology led to innovations in molecular cloning and chimeric plasmid construction. Advances in nucleic acid sequencing allowed researchers to gain a better understanding of genes and the ability to study gene mutations. Unraveling the minutiae of molecular events involved in gene transcription and translation furthered the analysis of cellular pathways and their complex interrelationships. Production of proteins ex vivo allowed physicians to treat diseases such as diabetes with synthetic human insulin, ending the dependency on animal sources.
