Description
Pure bred wild-type (129S1/SvImJ) and PPAR-null (129S4/SvJae) mice were treated for 6 hours with the synthetic triacylglycerols triolein [oleic acid (OA, C18:1)], trieicosapentaenoin [eicosapentaenoic acid (EPA, C20:5)] or tridocosahexaenoin [ocosahexaenoic acid (DHA, C22:6)], or the potent PPAR agonist WY14,643
Data processing
Expression estimates were calculated using GCRMA, applying the emperical Bayes estimate
