Hypothesis
The transcriptional relationship among the three large maf genes and their roles in lens development remain to be elucidated.
Conclusion
Large Maf function is essential for chick lens initiation and development, with L-Maf positively regulating key genes in this process.
Supporting Evidence
- Maf proteins are crucial for lens development in vertebrates.
- L-Maf is expressed first, followed by c-Maf and then MafB.
- Misexpression of L-Maf and c-Maf affects the expression of gap junction genes.
Takeaway
Maf genes help the chick eye develop properly by controlling other important genes, like those that make the lens clear.
Methodology
Chick embryos were electroporated with maf genes, and gene expression was analyzed using in situ hybridization and immunostaining.
