Hypothesis
What are the effects of Cathepsin D knock-down on zebrafish development?
Conclusion
Cathepsin D is crucial for proper organ development and function in zebrafish, affecting the retina and swim bladder.
Supporting Evidence
- Zebrafish lacking Cathepsin D showed reduced body length and microphtalmia.
- Rescue experiments confirmed that the lack of Cathepsin D directly caused developmental anomalies.
- Cathepsin D is essential for the development of the retinal pigment epithelium.
Takeaway
Cathepsin D helps zebrafish grow properly; without it, they have problems like small eyes and no swim bladder.
Methodology
Zebrafish were injected with morpholino oligonucleotides to knock down Cathepsin D, and phenotypic alterations were assessed.
Potential Biases
Potential bias in interpreting phenotypic outcomes based on subjective assessments.
Limitations
The study primarily focuses on early developmental stages and may not capture long-term effects.
Participant Demographics
Zebrafish (Danio rerio) embryos and larvae were used in the study.
