Table 2.

The methylation ratio of CpG loci in BARF1p and BHRF1p before and after 5-aza treatment.

Cell line	Treatment	Methylation rate
		BARF1	BHRF1
B95-8	0 μmol/L 5-aza	46.7%∗ (140/300)	32.7%∗ (51/156)
	10 μmol/L 5-aza	0 (0/300)	0 (0/300)
GT39	0 μmol/L 5-aza	94.7%∗ (284/300)	99.4%∗ (155/156)
	10 μmol/L 5-aza	43.0% (129/300)	53.2% (83/156)
GT38	0 μmol/L 5-aza	95.3%∗ (286/300)	97.4%∗ (152/156)
	10 μmol/L 5-aza	75.0% (225/300)	52.6% (82/156)

^∗The difference of methylation rate is significant (P < 0.05).
