Figure 1. ITGA9 promoter is demethylated by demethylation reagent 5′-aza-C in NPC C666–1 cell line where its expression is also downregulated.
A. Methylation status of ITGA9 analyzed in control nasopharyngeal epithelium derived cell line NP69 and NPC C666-1 cell line treated with 5′-aza-C by MSP. B. mRNA expression status of ITGA9 analyzed in control nasopharyngeal epithelium derived cell line NP69 and NPC C666-1 cell line by Q-PCR.
