The ability of Jun proteins to cooperate with GR in T cells has been investigated after transfection of c-jun , jun-B , or jun-D expression vectors , which augmented GR -dependent transcription from either MMTV LTR or GRE .
 ( DNA: MMTV LTR, None) , ( cell type: T cells, None) , ( protein: GR, None) , ( DNA: GRE, None) , ( protein: Jun proteins, None) , ( protein: GR, None)
