Intraflagellar transport (IFT) proteins regulate heart development by modulating YAP1, a key component of the Hippo pathway. This discovery reveals a novel mechanism linking cilia function to congenital heart disease pathogenesis.
Area of Science:
- Cardiovascular Biology
- Cell Biology
- Developmental Biology
Background:
- Cilia and intraflagellar transport (IFT) proteins are implicated in congenital heart diseases (CHDs).
- The precise molecular mechanisms connecting cilia, IFT proteins, and heart development remain unclear.
Purpose of the Study:
- To elucidate the molecular links between cilia, IFT proteins, and cardiogenesis.
- To investigate the role of IFT complex B proteins in regulating heart development.
Main Methods:
- Biochemistry
- Genetics
- Live-imaging in zebrafish and mouse models
- In cellulo experiments
Main Results:
- IFT complex B proteins (Ift88, Ift54, Ift20) modulate the Hippo pathway effector YAP1.
- This interaction is crucial for restricting proepicardium and myocardium formation.
- IFT88 and IFT20 interact with YAP1 in the cytoplasm, regulating its activity.
Conclusions:
- IFT complex B proteins play a noncanonical role in cardiogenesis.
- Ciliary proteins regulate YAP1 activity, providing a molecular link to congenital heart disease.
