Interaction between protein kinase C ( PKC )- and glucocorticoid receptor ( GR )-mediated signaling is suggested by the ability of the PKC activating phorbol ester 12-O-tetradecanoylphorbol-13-acetate ( TPA ) to inhibit GR -dependent transcription of the mouse mammary tumor virus ( MMTV ) long terminal repeat ( LTR ).
