Hypothesis
What are the regulatory mechanisms of cold stress in red tilapia during overwintering?
Conclusion
Cold stress may promote apoptosis in red tilapia through the FoxO signaling pathway and affect amino acid metabolism via ABC transporters.
Supporting Evidence
- Cold stress led to significant changes in serum physiological parameters of red tilapia.
- Transcriptome sequencing and metabolome analysis revealed key pathways affected by cold stress.
- The FoxO signaling pathway was identified as crucial for regulating apoptosis under cold stress.
- ABC transporters were found to play a role in amino acid metabolism in response to cold stress.
Takeaway
When red tilapia get too cold, it can make them sick and even die. This study helps us understand how to make them stronger against the cold.
Methodology
The study involved dividing red tilapia into cold stress and control groups, measuring physiological parameters, and conducting transcriptome and metabolome analyses.
Participant Demographics
Red tilapia (Oreochromis spp.) with an initial weight of 72.71 ± 1.32 g.
