Study IDST000584
Study TitleFasting wildtype, tfeb -/- knockout, and lmna -/- knockout metabolite profiling of adult zebrafish
Study SummaryInhibition of mechanistic target of rapamycin (mTOR) activity exerts cardioprotective functions. We propose to assess the metabolite profile in zebrafish cardiomyopathy models to test the cardioprotective role of mTOR-TFEB-autophagy and mTOR-lmna- autophagy signaling in heart, liver, muscle, brain, and kidney tissue. In addition mTOR signaling among zebrafish 2 hour post feeding, 24 hour post feeding, and 48 hour post feeding will be profiled. These studes will be used as a baseline and for protocol development before we assess changes in DOX-induced cardiomyopathy.
