Figure 2. Comparison of inferred lncRNA expression and actual lncRNA expression.

(A) Number of lncRNA regulons identified in 23 TCGA cancer types from the ARACne algorithm. Each regulon consists of a lncRNA and its associated protein coding genes. (B) Distribution of Spearman correlation coefficients from comparing inferred lncRNA expression with its actual expression using RNA-seq data from 23 TCGA cancer types.
