Implication
Randomized trial reveals miR-430's role in balancing Nodal agonist and antagonist, implying significance in physiological regulation.
Key Points
- The aim is to understand how miR-430 influences the expression of Nodal agonist squint and antagonist lefty in zebrafish.
- Developed target protector morpholinos to disrupt miR-430 binding to squint and lefty mRNAs.
- Protected squint or lefty mRNAs from miR-430 to analyze effects on Nodal signaling.
- Examined simultaneous protection of both mRNAs and its impact on signaling.
- Protection of squint mRNA enhanced Nodal signaling, while protection of lefty mRNA reduced Nodal signaling.
- Simultaneous protection caused an imbalance and reduction in Nodal signaling.
- miR-430 is crucial for dampening and balancing agonist and antagonist interactions.
