PDLIM7 and disease arising from reactivation of latent virus: Using RT-PCR, we detected EBV-related gene expression after infection, including expression of the pyrolysis-related protein EBV BZLF1(Zta) and expression of the early gene (EA), both of which appear during the hyperplastic cracking stage of infection,as well as of related genes such as LMP1, EBNA1 and EBNA2 that appear in the latent infection stage.
