The effect of ADP-ribosylation on transcriptional activity in isolated nuclei from spleen of adult male rats irradiated with 8 Gy gamma-rays was studied. The results showed the activities of RNA pol(Ⅰ+Ⅲ) were all inhibited by ADP-ribosylation and this inhibition was lost in the presence of 3-AB, a specific inhibitor of ADPRT. It confirmed the effect of ADP-ribosylation. The fact that ADPRT activity decreased within 4 hours after irradiation and subsequently restored entirely after 18 hours showed irradiation of 8 Gy gamma ray inhibited the ADPRT activity and the effect of irradiation disappeared quickly.
