M. Hayashi et al., ENHANCEMENT OF MESSENGER-RNA SYNTHESIS FROM MAREKS-DISEASE VIRUS GENOME IN THE LYMPHOBLASTOID CELL-LINE, MDCC-MSB1, BY 5-AZACYTIDINE, Journal of veterinary medical science, 56(2), 1994, pp. 287-291
Marek's disease virus (MDV) DNA in latently infected lymphoblastoid ce
ll lines is considerably methylated. A treatment of the MDV-derived ly
mphoblastoid cell line, MDCC-MSB1 (MSB1), with 5-azacytidine (5-AzC) r
esulted in a hypomethylation of MDV DNA and an increase in mRNA from c
ertain portions of the MDV DNA. These results suggest methylation of M
DV DNA as being one of the factors associated with a repression of tra
nscription of MDV DNA in the lymphoblastoid cell line, MSB1.
