Abstract:
Inherited mitochondrial mutations can result in mitochondrial dysfunction or stochastic oxidative damage. Cumulative mitochondrial damage is an important factor in age-related disorders, such as cataracts and macular degeneration. Mfn2 mediates the fusion of mitochondria and contribute to the dynamic balance between fusion and fission that determines mitochondria morphology. We report here that conditional loss of Mfn2 function in the head surface ectoderm leads to a range of congenital eye defects, including small, opacified lens and small eyeball in the most severe phenotypes. The Le-Cre transgenic mouse line and Mfn2 flox mouse line were used in this study to generate Mfn2 conditional knockout mice. Our study revealed Mfn2 gene function in lens development and addressed the relationship between the mitochondria and lens transparency. Conditional loss of Mfn2 affected lens epithelium cell proliferation, apoptosis and ultrastructure of mitochondria. We conclude that proper development of the lens and lens transparency depend on normal Mfn2 gene function.
