Fig. 1From: Artichoke phytocomplex modulates serum microRNAs in patients exposed to asbestos: a first step of a phase II clinical trialA Supervised hierarchical clustering representing differentially expressed miRNAs before (baseline) and after (treatment) artichoke leaf extract treatment. Red and green colours show high and low standardized expression levels, respectively. B Principal component analysis representation of samples before (baseline) and after (treatment) artichoke leaf extract treatment obtained from the 11 miRNAs signature. C-D Boxplot analysis representing the distributions of the 11 miRNAs signature. Differences in the miRNA expression are evaluated by Wilcoxon testBack to article page
