Both PPAR-alpha and PPAR-gamma mRNAs were detected in HAECs by using reverse transcription-polymerase chain reaction and a ribonuclease protection assay ; however, we have yet to determine which, if any, of the PPARs are mediating this process.
 ( RNA: PPAR-gamma mRNAs, None) , ( protein: PPARs, None) , ( protein: ribonuclease, None) , ( RNA: PPAR-alpha and PPAR-gamma mRNAs, None) , ( RNA: PPAR-alpha, None) , ( cell type: HAECs, None)
