Hypothesis
Psf2 is necessary for normal eye development in Xenopus laevis.
Conclusion
Psf2 is crucial for the development of both the retina and lens, with defects in retinal development leading to lens issues.
Supporting Evidence
- Psf2 knockdown led to eye defects like microphthalmia and retinal dysgenesis.
- Co-injection of synthetic Psf2 RNA rescued some developmental defects.
- Significant increases in apoptosis were observed in retinal tissues after Psf2 knockdown.
Takeaway
Psf2 helps frogs' eyes grow properly, and if it's not working right, the eyes can be small or misshapen.
Methodology
Morpholino was used to knock down Psf2 in embryos, and effects on eye development were assessed through various assays.
Limitations
Not all tissues expressing Psf2 showed defects, indicating potential redundancy or differences in translation.
