Figure 2From: A systems biology approach reveals a link between systemic cytokines and skeletal muscle energy metabolism in a rodent smoking model and human COPDOverlap analysis of enriched KEGG pathways in guinea pig lung tissue. Rectangles coloured in green indicate pathways unique to a specific experimental condition (that is, CS, CH or CSCH). Grey-coloured rectangles indicate pathways that are regulated by more than one condition.Back to article page
