Figure 8From: Comparison and evaluation of pathway-level aggregation methods of gene expression dataExpression profiles of MAPK signalling pathway as an example of discordant pathway. Expression profiles of MAPK signalling pathway in the two cohort datasets of lung cancer grade are shown. (A) Expression profile of 244 member genes. (B) Pathway expression profiles aggregated by the six methods. In grade 3, the pathway shows an up-regulation in the Dana-Farber cohort but a down-regulation in the Michigan cohort.Back to article page
