To investigate the inhibitory mechanisms, we constructed a secreted-type placental alkaline phosphatase ( PLAP ) reporter gene whose transcription is controlled by a 1.4-kb human TNF-alpha promoter .
 ( protein: placental alkaline phosphatase, None) , ( DNA: secreted-type placental alkaline phosphatase ( PLAP ) reporter gene, None) , ( DNA: 1.4-kb human TNF-alpha promoter, None) , ( protein: PLAP, None)
