From: Bronchial biopsy specimen as a surrogate for DNA methylation analysis in inoperable lung cancer
Relationship among methylation levels of 10 genes. a Protein-protein interaction was determined by the STRING protein interaction database (https://string-db.org/). b–d Correlation among methylation levels of genes for each of the three GO categories (transcription, cell signaling, and cell adhesion) was analyzed using Spearman’s correlation coefficient in 42 lung cancers. Magenta color indicates P < 0.05
