Outline of Final Research Achievements

In the inherited lens rupture cataract mouse model derived from CF#1 mice (CF#1/lr mice), the white pin head opacity is the first sign of lens rupture. Then, the opacity becomes enlarged and finally results in an entirely white eye. The lens rupture is induced by abnormality of gene (Bcar3) related to the breast cancer. Although lens rupture is often complicated by endophthalmitis, CF#1/lr mice do not develop endophthalmitis. The levels of αB crystallin, one of the heat shock proteins protecting lens, and phosphorylated αB crystallin (PαB crystallin) which is increased by stress were decreased in the lens of CF#1/lr mice. This may be related to the characteristics of CF#1/lr mice do not develop endophthalmitis despite lens rupture.
