Ed cells. Furthermore, TNF- stimulation led to the appearance of Sp1 and initiating RNAPII on the 5'LTR and additional enrichments of initiating and elongating RNAPII on the 3'LTR. These effects are most likely achieved through the activation of NF-B, which stimulates several steps of viral transcription including the PIC formation, transcription initiation and transcription elongation. Thus, our
