Hypothesis
Species specific differences in TnT gene expression in teleosts underlies different larval muscle developmental programs.
Conclusion
Muscle organization in halibut remains symmetrical even after metamorphosis suggesting thyroid hormone driven changes are associated with molecular adaptations.
Supporting Evidence
- Five cDNAs for halibut TnT genes were cloned.
- THs modified the expression of halibut fTnT isoforms.
- Expression of red muscle specific genes did not change during metamorphosis.
- Muscle organization remained symmetrical before, during, and after metamorphosis.
Takeaway
This study looks at how a protein important for muscle function changes in halibut as they grow up, showing that their muscles stay balanced even when their bodies change shape.
Methodology
cDNAs for slow and fast TnT were cloned and their expression and tissue distribution was studied in relation to changing thyroid hormone concentrations and muscle development.
