Using electrophoretic mobility shift assay, we demonstrated that a short treatment of human T lymphocytes with PGE2 induces specific binding activity to CRE and AP-2 , but not AP-1 , DNA elements .
 ( DNA: AP-1 , DNA elements, None) , ( DNA: CRE, None) , ( protein: AP-1, None) , ( DNA: AP-2, None) , ( cell type: human T lymphocytes, None)
