Hypothesis
The absence of Crabp2 proteins affects germ cell proliferation and sex determination in zebrafish.
Conclusion
Crabp2 proteins are essential for germ cell proliferation and play a critical role in sex determination in zebrafish.
Supporting Evidence
- Crabp2 proteins are crucial for maintaining female sex determination in zebrafish.
- Loss of Crabp2 leads to a significant increase in male zebrafish.
- Exogenous retinoic acid treatments promote germ cell proliferation.
Takeaway
Some proteins help zebrafish grow their baby-making cells and decide if they will be boys or girls.
Methodology
The study used CRISPR-Cas9 to create loss-of-function mutations in zebrafish Crabp genes and analyzed the effects on germ cell development and sex determination.
