Hypothesis
The study investigates the role of globin genes in the salinity adaptation of flounder.
Conclusion
The kidney is the major site of globin gene expression in flounder, with higher expression levels in freshwater-adapted fish compared to seawater-adapted fish.
Supporting Evidence
- Globin gene expression was significantly higher in the kidneys of freshwater-adapted flounder compared to seawater-adapted flounder.
- The kidney was confirmed as the major site of globin expression in flounder.
- Expression levels of α-globin and β-globin mRNA were higher in freshwater than in seawater.
- Total nitric oxide levels in the kidneys were double in freshwater-adapted fish compared to seawater-adapted fish.
Takeaway
Flounders have special genes that help them live in both fresh and salty water, and these genes work better when they are in fresh water.
Methodology
The study involved collecting flounder from different salinities, measuring blood samples, and analyzing globin gene expression using real-time PCR and other molecular techniques.
Limitations
The study may not account for all environmental factors affecting globin expression in flounder.
Participant Demographics
Flounder of mixed sex, weighing between 300 to 500 g.
