Absence of S100A4 in the mouse lens induces an aberrant retina-specific differentiation program and cataract.

ABSTRACT: S100A4, a member of the S100 family of multifunctional calcium-binding proteins, participates in several physiological and pathological processes. In this study, we demonstrate that S100A4 expression is robustly induced in differentiating fiber cells of the ocular lens and that S100A4 ^(-/-) knockout mice develop late-onset cortical cataracts. Transcriptome profiling of lenses from S100A4 ^(-/-) mice revealed a robust increase in the expression of multiple photoreceptor- and Müller glia-specific genes, as well as the olfactory sensory neuron-specific gene, S100A5. This aberrant transcriptional profile is characterized by corresponding increases in the levels of proteins encoded by the aberrantly upregulated genes.
