We aim to detect differential expressions of LMP genes(LMP-1,LMP-2A,LMP-2B) in normal human lymphocytes and EBV-transformed lymphoblasts in vitro.Firstly,expression levels of LMP genes(LMP-1,LMP-2A,LMP-2B) in the two kinds of cells were detected by using real-time PCR.Then LMP-1 protein expression was detected by Western bolt in the normal lymphocytes and EBV-transformed lymphoblasts.It was found that LMP-1 mRNA expression was 863 times up-regulated in the transformed lymphoblasts,as compared with that in the normal lymphocytes(P 0.01).Co...
