Surprisingly, although it is known that the expression of ADAR1-p150 is induced following interferon (IFN) treatment [25] (Fig. S1b, quantified in Fig. S1c), only the expression of ADAR1-p110, which was considered until now constitutive, significantly increased following HCMV infection (Fig. 1a, quantified in Fig. S1d). This evidence concerns the gene ADAR and cytomegalovirus infection.
