| Outline of Final Research Achievements |
Genetic and environmental factors are believed to be involved in the onset of age-related macular degeneration (AMD).We generated three mouse lines that overexpressed mouse HtrA1, human ARMS2 and ARMS2(A69S) throughout the entire mouse body. CNV similar to human AMD was observed progression in HtrA1 Tg mouse at 12-month-old. Exposure to mainstream cigarette smoke enhanced the CNV rate in HtrA1 Tg mouse. Our data suggested that HtrA1 overexpression alone is a strong risk factor for wet AMD, which is the predominant form of AMD in the Japanese population.
