Cluster maps of genes in biological processes enriched in set of genes with consistent expression change ( ≥25%) in the majority of overweight subjects. Expression changes (2log ratio) of intervention spread versus placebo spread in eight overweight subjects were submitted to gene and sample clustering (using average linkage clustering and uncentered correlation as similarity metric). Red color indicates up-regulation of expression in response to intervention spread compared to placebo spread. Green color indicates down-regulation of expression in response to intervention spread compared to placebo spread. Asterisks are significantly different expression in overweight compared to lean subjects (BMI-effect) and expression changed in response to the intervention spread in direction of expression levels in lean subjects (colour in online)
