FADS2 and hyperlipidemia: Gene ontology enrichment analysis showed that genes associated with liver development, blood coagulation, triglyceride homeostasis and response to oxidative stress were altered, increased expression of genes associated with hyperlipidemia such as cyp 51, acox1, hmox1a, and fads2 as well as increase in the activity of signaling pathways associated with metabolic regulation in zebrafish on high fat diet.
