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; protein: PPARs; protein: ribonuclease; RNA: PPAR-alpha and PPAR-gamma mRNAs; RNA: PPAR-alpha; cell type: HAECs
