The analysis of SNCA promoter methylation level in LUAD. A The correlation analysis between the expression level of SNCA in LUAD samples and the methylation level of cg06632027 methylation site. B The analysis of methylation levels of four genomic fragments of SNCA promoter in tumor samples and normal samples in LUAD patient samples of the DiseaseMeth database. The expression level of SNCA methylation in LUAD patient samples downloaded from UALCAN database was analyzed with (C) sample type, (D) TNM stage, and (E) lymph node status. F After A549 and H1299 cells were treated with 5-aza-dC, the mRNA expression level of SNCA was detected by qPCR (* P < 0.05, ** P < 0.01, *** P < 0.001, **** P < 0.0001)
