Role of Long Noncoding RNAs in Smoking-Induced Lung Cancer: An In Silico Study

Figure 2

Effects of smoking on lung cancer. (a and b) The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) datasets; each tree fork represents a collection of genes for which the band is a series of modules. (c and d) Relationship between gene modules and traits in the GEO and TCGA datasets; pink represents positive and green denotes negative relation between traits and genes. The two databases contain 44 genes that are positively (e) and 80 genes that are negatively (f) associated with smoking.
