Hypothesis
Is the abnormal lens development in the Iberian mole a result of degenerated or developmentally retarded visual system?
Conclusion
The lens development in the Iberian mole is incomplete, leading to a disorganized structure and loss of the anterior epithelial phenotype.
Supporting Evidence
- Lens fibre differentiation is not completed in the Iberian mole.
- PAX6 is not down-regulated in developing lens fibre nuclei.
- FOXE3-positive lens fibres continue to proliferate within the posterior compartment of the embryonic lens.
- Most anterior epithelial cells undergo apoptosis.
- β-crystallin and PROX1 expression patterns are abnormal.
Takeaway
The Iberian mole's eyes are not fully developed, which means their lenses don't work like normal lenses, leading to problems with vision.
Methodology
The study involved morphological analysis, immunohistochemistry, and TUNEL assays on various developmental stages of the Iberian mole.
Limitations
The study is limited by the availability of wild specimens and the challenges in obtaining fresh embryonic material.
Participant Demographics
The study analyzed 64 embryos, foetuses, infants, and adult Iberian moles.
