Background: The visual cycle is an enzymatic cascade that regenerates the visual chromophore. Results: Visual cycle gene expression is regulated by SOX9 in combination with OTX2 or LHX2 and can be modulated by common microRNAs. Conclusion: A core transcriptional network involving SOX9 regulates visual cycle genes. Significance: Understanding visual cycle gene regulation may have implications for treating retinal degenerative diseases.
